Road map for updating the NetWorker software Use this road map to update the NetWorker software from a previous release.
Procedure
1. Review the Introduction chapter for general information.
2. Review the Software Requirements chapter for general requirements and considerations.
3. Review the Updating the NetWorker software chapter for instructions on how to update the software. To update the NetWorker software by using Package Manager or to update from a 32-bit version of NetWorker to a 64-bit version, review the Updating Methods chapter.
4. Review the Post Update Tasks chapter to test the NetWorker software functionality.
5. (Optional) If you update the NetWorker software from 8.1.x or 8.2.x, review the Reviewing the Migration Status chapter for information about changes in NetWorker that occur after you update .
6. Review the Troubleshooting NMC GUI and NetWorker Server Connection Issues chapter for information about how to troubleshoot issues that you might encounter after the upgrade completes.
Introduction This guide provides you with the information to review before you upgrade a NetWorker host to 19.1 and provides detailed information about the update procedure on each supported operating system.
It is recommended that you update the hosts in the datazone in the following order:
1. NetWorker Server. On Linux, also configure NetWorker Authentication Service.
2. NMC Server.
3. All NetWorker Storage Nodes.
4. NetWorker Clients.
Before you upgrade the NetWorker Server, consider the following information:
l You can upgrade NetWorker Server that runs version 8.2.x, 9.0.x, 9.2.x or 18.x on a supported 19.x operating system directly to version 19.x.
l To upgrade a NetWorker Server that runs version 8.0.x on a supported 19.x operating system to version 19.x, update the NetWorker Server to version 8.2.x and then update the NetWorker Server to version 19.x.
This guide uses NetWorker_install_dir and NMC_install_dir variables to describe the installation directories. The default installation path for the NetWorker and NMC software on Windows changed in some releases. The update process does not change the directory location. The following table summarizes the default directory locations that the NetWorker_install_dir and NMC_install_dir variables represent.

Table 3 Default installation directories for NetWorker and NMC software
Earliest version of the installed software on the host
Default directory location that is used in the update process
NetWorker 8.0.x or earlier C:\Program Files\Legato\nsr
NetWorker 8.1.x, 8.2.x, 9.x and later C:\Program Files\EMC NetWorker\nsr
NMC Server 8.0.x or earlier C:\Program Files (x86)\Legato\Management \GST\
NMC Server 8.1.x, 8.2.x, 9.x and later
C:\Program Files\EMC NetWorker \Management
Interoperability and Backward Compatibility Before you update any host in the datazone, review information about the interoperability and backward compatibility. If you are updating the operating system on a host, update the operating system first, and then update the NetWorker software.
NetWorker supports Data Domain systems with a minimum version of DDOS 5.7. Before you update the NetWorker software on the NetWorker hosts, ensure that all Data Domain systems run a supported DDOS version. The NetWorker E-LAB Navigator provides more information about the supported DDOS versions, the NetWorker version interoperability and backward compatibility requirements
Note
l The module installation guides provide detailed information about how to upgrade NetWorker module clients, for example, NetWorker Module for Microsoft (NMM), NetWorker Module for SAP (NMSAP), and NetWorker Module for Databases and Applications (NMDA).
l If RPS cloning is enabled, then it is highly recommended to run NetWorker server and Storage Node on 19.1 version.
l NetWorker 19.1 supports storage node of NetWorker version 18.2, 18.1 and 9.2.2 with RPS disabled.
Clone performance considerations In NetWorker 19.1, Recover Pipe to Save (RPS) clone is disabled by default. When you update the NetWorker Server from 8.2.x to NetWorker 19.1, RPS is disabled. When you update the NetWorker Server from 9.0.x or 9.1.x to NetWorker 19.1, the updating process preserves the value that you defined for the Disable(RPS) Clone attribute.
To modify the RPS clone attribute, see the NetWorker Administration Guide for more information.
Note
When you perform a fresh installation of NetWorker Server 19.1, RPS cloning is disabled by default.

Interoperability and Backward Compatibility 21
NMC Client A NetWorker Management Console (NMC) client is any host in the environment that uses a web browser and NetWorker Runtime Environment or Java Runtime Environment (JRE) to display the NMC Server GUI. Multiple users can access the NMC Server GUI simultaneously, from different browser sessions.
NetWorker Daemons The NetWorker software uses processes on Windows or daemons on UNIX to control and manage NetWorker operations in the datazone.
This table lists the NetWorker daemons for each software component.
Table 4 Daemons on a NetWorker host
Software component Daemons
NetWorker Authentication Service java.exe (Windows), jsvc.exec (UNIX)
NetWorker Server nsrd, nsrexecd, nsrindexd, nsrmmdbd,

NetWorker Storage Node nsrexecd, nsrmmd, nsrlcpd, nsrsnmd
NetWorker Management Console server gstd, httpd, postgres, tomcat,
gstsnmptrapd (optional)
For more information about the NetWorker processes, review the following information:
l The nsrmmd daemon or the nsrmmd.exe process is present on a NetWorker Server or storage node that has one or more enabled devices.
l The nsrmmgd daemon or the nsrmmgd.exe process is present on the NetWorker Server when a media manager is enabled.
l The nsrlcpd daemon or the nsrlcpd.exe process is present on a NetWorker Server and storage nodes when an attached tape library exists.
l The nsrcpd daemon or the nsrcpd.exe process is present on the NetWorker Server during a Package Manager software upgrade.
The NMC Server daemon, gstd, starts these additional processes:
l postgres: The ProgreSQL database daemon on Linux. On Windows, the service associated with the postgres.exe process is EMC GST Database Service.
l httpd: The web server daemon on Linux. On Windows, the service associated with the httpd.exe process is EMC GST Web service. There are 2 or more httpd daemons.
l gstsnmptrapd: An optional daemon that is present on a Linux NMC Server when SNMP Trap monitoring is configured for a Data Domain system. On Windows, the
Preparing to Update the NetWorker Software
22 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
service associated with gstsnmptrapd.exe process is EMC GST Trap Handler.
Note
On Windows platform, after NetWorker server upgrade, the NetWorker services fail to start, and the daemon.raw logs a message notifying that RabbitMQ service failed to start. To fix this issue, you must delete the RabbitMQ folder located in C:\Windows \System32\config\systemprofile\AppData\Roaming file path and restart the services.
Dell EMC Licensing Solution NetWorker 9.0.x and later servers use the Dell EMC Licensing Solution.
The Dell EMC Licensing Solution is a licensing standard that stores all licensing information for the environment in one license file, which is stored on both the NetWorker server and, if using a served license, the License Server.
All new installations of NetWorker use the Dell EMC Licensing Solution. The chapter "Dell EMC Licensing Solution" in the NetWorker Licensing Guide provides information on how to implement the Dell EMC Licensing Solution for new and upgraded installations of the NetWorker software. The "Dell EMC Licensing Solution" chapter also describes the Dell EMC Licensing Server and the use of the license file.

Software requirements 25
NetWorker Server Upgrades Review this section for information about changes to operating system support and changes to the NetWorker Server functionality in that started with 9.0.x.
Changes in operating system support NetWorker 19.1 supports the installation of the NetWorker Server and NMC Server software on Windows x64 or Linux x64 only. You cannot update a pre-19.1 AIX, HP- UX, or Solaris NetWorker Server to NetWorker 19.1. Deploy a new NetWorker Server on a supported Windows or Linux operating system. The NetWorker Installation Guide provides the required steps to install the NetWorker software.
If you use an 8.1.x and 8.2.x NetWorker Server on an operating system that NetWorker 19.1 does not support, you have two options:
l Perform a cross platform migration of the NetWorker Server data to NetWorker 19.1 server on a supported Windows or Linux host. Contact Professional Services for more information about cross platform migrations of the NetWorker Server data.
l Install and configure the NetWorker 19.1 server software on a supported Windows or Linux host and maintain the NetWorker 8.1.x and 8.2.x server for recovery purposes.
The NetWorker E-LAB Navigator provides more information about the operating system versions that the NMC 19.1 server software supports.
Changes to NetWorker Server databases and resources The NetWorker 19.1 server uses a SQLite database to store information in the media database. When you update the NetWorker Server software to 19.1 from previous supported versions, the upgrade process automatically converts the media database.
In NetWorker 9.0.1, the format of the jobsdb changed from a SQLite database to a Postgres database. Previous versions of the jobsdb, including the 9.0.x version are not compatible with NetWorker 19.1. The update process does not migrate the jobsdb data. When you update from a previous release to NetWorker 19.1, the updating process renames the jobsdb and the NetWorker Server uses a new database. After you update the NetWorker Server, the following behavior is seen:
l When you update from NetWorker 8.x, you cannot view details about previously run groups. The NetWorker 19.1 resources associated with these backup groups report a status of never run.
l When you update the NetWorker Server from the 8.x or 9.0.1 versions:
n Details about the policy, workflow, and action resources will report a status of never run.
n Recovery resources created before the update appear as expired.
Note
When you update the NetWorker Server on a Windows or Linux host, to NetWorker 19.1, you cannot revert to NetWorker 8.2.x. Contact Customer Service for more information. If the NetWorker Server is reverted back and Customer Service attempts a rollback, there is no guarantee that you can recover the data that was backed up while the NetWorker datazone was running the NetWorker 19.1 software, but Customer Service will provide a commercially reasonable effort attempt.

26 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
Changes to NetWorker backup method Previous releases of NetWorker use group-based configurations to perform scheduled backup and clone operations. NetWorker 19.1 uses policy-based configurations to perform schedule backup and clone operations. When you upgrade the NetWorker Server, the upgrade process migrates resource configurations to new policy configurations. The Differences between NetWorker 19.1 and Previous Releases Technical Note on the Online Support website provides detailed information about the changes in method and resource configurations with NetWorker 19.1.
Changes in Savegoup attributes After policy migration: After upgrading the NW server from 8.x to 9.x , schedule and default pool values of savegroup will be changed to default in the migrated workflows, under Backup policy. However, these legacy values will be preserved with the client override behavior option Legacy Backup rules in the backup action.
Changes in cloning save sets with backup levels 29 NetWorker 19.1 does not support backup levels 29. Before you update the NetWorker Server, clone all backup level 29 save sets, if required.
NetWorker Authentication Service NetWorker 19.1 uses the NetWorker Authentication Service to authenticate NetWorker Management Console (NMC) and command line interface (CLI) users.
To use a Linux NetWorker Server, install and configure the NetWorker Authentication Service package on the NetWorker Server host before you install NMC Server software.
When you use a Windows NetWorker Server host, the NetWorker Server installation automatically installs the NetWorker Authentication Service software on the NetWorker Server host.
The NetWorker Authentication Service requires NetWorker Runtime Environment or 64-bit Java 8. Before you start the NetWorker Server installation, install the Java provided in NetWorker Runtime Environment or the latest version of the 64-bit Java 8 on the host.
Before you install the NetWorker Server software, ensure that an application does not exist on the NetWorker Server that uses an Apache Tomcat instance on port 9090. The NetWorker Authentication Service listens on port 9090 by default. The section "Troubleshooting NMC GUI and NetWorker Server connection issues" provides more information.
Note
If the installation does not detect NetWorker Runtime Environment, 64-bit Java 8 on the host, the installation will not continue.
Java Requirements for a NetWorker Server The installation for the NetWorker Server software and the Linux configuration script for the NetWorker Authentication Service software check for the required Java version on a host. When the process or script does not detect the minimum required Java version (64-bit) on the host, the installation cannot continue. Before you start the NetWorker Server installation, install the Java provided in NetWorker Runtime Environment or the latest version of the 64-bit Java 8 on the host.
The following sections describe how to ensure that you are using the correct version of the Java software on a Windows or Linux NetWorker server.
Software requirements
NetWorker Authentication Service 27
Note
To install or upgrade to NetWorker 19.1, you must have either have NetWorker Runtime Environment or latest version of 64-bit Java 8 or 9 installed on the system.
Set the JAVA_HOME environment variable to JRE 1.8 Before you install the NetWorker software, if NRE is not installed then set the JAVA_HOME environment variable to the directory for the 64-bit JRE software.
Procedure
1. Log in to the target host with a user that has administrator privileges.
2. Browse to Control Panel > System > Advanced System Settings.
3. On the Advanced tab, click Environment Variables...
4. In the System Variables section, click New.
5. In the Variable name field, type JAVA_HOME.
6. In the Variable value field, type the path to the Java directory.
For example, C:\Program Files\Java\jre1.8.0_xx 7. Click OK.
8. Click OK to close the Environment Variables window, and then click OK to close the System Properties window.
NMC server upgrades Review this section for information about changes to operating system support and changes to the NMC Server database in 19.1.
Updating the NMC Server A 19.1 NMC Server uses the NetWorker Authentication Service on a NetWorker 19.1 server for authentication. Before you update the NMC Server, update the NetWorker Server.
On a Linux NetWorker Server, ensure that you configure the NetWorker Authentication Service and start the NetWorker services on the NetWorker Server before you update the NMC Server.
Changes in operating system support NMC 19.1 only supports Windows and Linux NMC Servers. You cannot upgrade a pre-9.x AIX, HP-UX, or Solaris NMC Server to 19.1. Deploy a new NMC Server on a supported Windows or Linux operating system. The NetWorker Installation Guide provides the required steps to install the NetWorker software.
Note
The NetWorker E-LAB Navigator provides more information about the operating system versions that the NMC Server software supports.
Changes with the NMC database The NMC 19.1 server uses a PostgreSQL database to store NMC data. An 8.x NMC Server uses a Sybase database. As a result, after you update the NMC Server software on a Windows or Linux host to version 19.1, you cannot directly roll back an 19.1 NMC Server to a previous version of the NMC Server software.
Software requirements
28 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
Note
When you update the NetWorker Server on a Windows or Linux host, to NetWorker 19.1, you cannot revert to NetWorker 8.2.x. Contact Customer Service for more information. If the NetWorker Server is reverted back and Customer Service attempts a rollback, there is no guarantee that you can recover the data that was backed up while the NetWorker datazone was running the NetWorker 19.1 software, but Customer Service will provide a commercially reasonable effort attempt.
NetWorker Management Console( NMC) version 19.1 and above ships with Postgres version 11.xx which has a dependency on Microsoft Visual Studio 2015/2017 runtime. Ensure that the required runtime is installed before installing NMC server. Runtime installation is required on Windows Server 2012 R2. The runtime is included in Windows Server 2016 and 2019 and separate installation is not required. You can either get the latest windows updates or install the security updates and the Visual C+ + Redistributable for Visual Studio 2015 or 2017 in the following sequence:
1. KB2919442
2. KB2919355
3. KB2999226
4. Install Visual C++ Redistributable for Visual Studio 2015 or 2017
If the dependencies are not installed, then
l New installation of NMC server and an upgrade from NMC version 8.x fails.
l If you are upgrading from NMC version 9.x, then the installation retains Postgres version 9.2.xx.
Linux NMC server considerations
The NetWorker software package provides a utility called gstdbunload, which converts the NMC data from a Sybase database format to a platform independent format, called an Unload Database. Before you update the NMC Server software on Linux, convert the NMC database.
HP-UX, Solaris, and AIX NMC Server considerations
NetWorker 9.0.x does not support an NMC Server on the HP-UX, Solaris, and AIX operating systems.
The NetWorker software package provides a utility called gstdbunload, which converts the NMC data from a Sybase database format to a platform independent format, called an Unload Database. Use this utility to convert NMC data from a NetWorker 8.2.x and earlier AIX, HP-UX or Solaris server. Before you deploy a new NMC Server in your datazone, use the gstdbunload to convert the NMC data on the AIX, HP-UX, or Solaris NMC Server, and then copy the Unload Database to a location that is accessible to the new target Windows or Linux NMC Server.
The chapter Updating NetWorker for UNIX from 8.2.x provides more information about how to use the gstdbunload command on AIX, HP-UX, and Solaris NMC Server.
Windows NMC Server considerations
The updating process for Windows provides you with the ability to automatically convert the NMC database. When you update a supported Windows NMC Server, it is recommended that you allow the updating process to automatically convert the database. If your 8.2.x NMC Server is on a Windows operating system that NetWorker 19.1 does not support, you must use the gstdbunload utility
Software requirements
NMC server upgrades 29
included with the NetWorker 19.1 software package to convert the NMC database into a platform independent format. After you convert the database, you must copy the converted files to the Windows or Linux host that will become the new NMC Server.
NMC Server Features and System Requirements The NetWorker Management Console server (NMC Server) enables you to manage, monitor, and generate reports for multiple NetWorker Servers across multiple datazones and from a single host.
The NMC Server embeds the following software:
l Apache server, which downloads NMC jar files and starts the NMC Server daemons or services.
l PostgreSQL database, which stores reports and the NMC Server configuration information.
The NMC Server software package is supported on a Linux or Microsoft Windows host. The NMC Server software requires the NetWorker Client software.
You can install the NMC Server software on the NetWorker Server. The minimum system requirement for a NMC Server host is a 2 CPU processor and 8GB of RAM.
If NMC server is handling a large scale NetWorker server with a large number of users, then size the NMC server with 32 GB RAM and 8 core CPU, with greater than or equal to 1.5 GHz.
It is recommended that you install the NMC Server software on a host that is not the NetWorker Server in the following scenarios:
l When the NMC Server manages a NetWorker Server with 50 or more clients.
l When the NMC Server monitors multiple datazones.
NMC Browser and JRE Requirements An NMC client is any host in the datazone in which you use a web browser to connect to the NMC GUI to manage the NMC server and NetWorker servers.
The following table summarizes the supported Java (JRE) versions and browsers .
Table 5 Supported Browsers and JRE versions

Preparing the Linux host for a NetWorker software or NMC server software update
Before you update the NetWorker software or NMC server software on Linux, review the following information.
Preparing the NetWorker server Before you update the NetWorker server, ensure that the media database and client file indexes are in a consistent state, and that you have a backup of the databases.
Procedure
1. Connect to the NetWorker server as root on UNIX and administrator on Windows, and then open a command prompt.
2. Put the NetWorker databases in a consistent state:
nsrim -X nsrck -m nsrck -L6
3. Record the current location of the NetWorker client file indexes:
nsrls
4. Record the range of ports the NetWorker software uses:
nsrports
5. Perform a server backup by starting the Server backup workflow.

36 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
Ensure that the media pool associated with the backup action has appendable media available.
6. Record the latest bootstrap save set ID (ssid) including the file number, the record number, and the associated volume label.
For example:
mminfo -B
date time level ssid file record volume 10/11/11 16:29:40 full 4254377781 0 0 bootstrap_vol.001 In this example:
l The save set ID (ssid) is 4254377781.
l The file number is 0.
l The record number is 0.
l The label of the volume that contains the bootstrap save set is bootstrap_vol.001.
SuSE Package Requirements The NetWorker software has OS package dependencies. The default SuSE installation does not contain all the operating system packages that the NetWorker software requires.
When you use the rpm command to install the NetWorker software, the installation displays a list of missing required OS packages. You must install the required packages before you install the NetWorker software.
For example, when you run the rpm command to install the NetWorker software on a default installation, output similar to the following might appear:
rpm -ivh lgtoclnt-19.1-0.x86_64.rpm error: Failed dependencies: libcap.so.1()(64bit) is needed by lgtoclnt-19.1-0.x86_64 libstdc++.so.5()(64bit) is needed by lgtoclnt-19.1-0.x86_64 libstdc++.so.5(CXXABI_1.2)(64bit) is needed by lgtoclnt-19.1-0.x86_64 libstdc++.so.5(GLIBCPP_3.2)(64bit) is needed by lgtoclnt-19.1-0.x86_64 libstdc++.so.5(GLIBCPP_3.2.2)(64bit) is needed by lgtoclnt-19.1-0.x86_64 To resolve this issue, install the following OS packages, and then run the rpm command again:
l compat-libstdc++-33-3.2.3-68.1.x86_64.rpm l libcap1-1.10-47.1.x86_64.rpm
RHEL 7 and CentOS Package Requirements The NetWorker installation requires some packages that the default OS installation might not include.
Manually download and install the following Linux OS packages. The NetWorker installation fails when these packages do not exist on the host:
Updating NetWorker for Linux
Preparing the Linux host for a NetWorker software or NMC server software update 37
l ksh l glibc.i686 0:2.17-55.el7 or later l nss-softokn-freebl.i686 0:3.15.4-2.el7 or later
Note
For PowerPC (PPC) hosts, install the 32-bit Pluggable Authentication Modules (PAM) library, pam-1.1.8-12.el7_1.1.ppc or later, on the host. NetWorker requires the 32-bit package, even when the 64-bit PAM package exists on the host.
Updating the NetWorker software You can use the rpm -U command to update the NetWorker client, server, and storage node software without first removing the previous version of the software.
Before you begin
Before you remove the NetWorker software, remove the NetWorker module software. The NetWorker module software includes the NetWorker Module for Database Applications software. The appropriate module installation guide describes how to uninstall the module software.
Before you start the NetWorker Server update, install the Java provided in NetWorker Runtime Environment or the latest version of the 64-bit Java 8 on the host. Before you install the Java software, stop NMC and any running NetWorker Server daemons.
Procedure
1. Download the NetWorker software package from the Online Support website to a temporary location.
Ensure that there is sufficient disk space on the host.
2. Change to the temporary location that contains the software package, and then unzip and extract the files by typing the tar command.
For example:
tar -xzf file_name.tar.gz
3. Stop the NetWorker service.
4. Use the rpm -qa | grep lgto command to display the list of installed NetWorker packages.
5. From the directory that contains the latest version of extracted NetWorker software packages, type:
rpm -Uvh package [package]... where:
l package [package]... is a list of the software package for the installation type.
Note
The Block-Based Backup (BBB) package requires a different command. Do not include the package in the update command.
l You specify optional packages such as language packs and man pages in rpm command after the required packages for the installation type.

To resolve this issue, perform the following steps:
1. Determine the NMC installation path, by default the NMC installation path is /opt/lgtonmc.
2. Add the NMC odbc directory to the LD_LIBARARY_PATH variable. For example, when the NMC installation path is the default location, type the following command:
export LD_LIBRARY_PATH=/opt/lgtonmc/postgres/odbc 3. Initialize the NMC database, by typing the following command:
NMC_installation_path/bin/gstdbinit -U nsrnmc -n 5432 NMC_installation_path/nmcdbXX where: NMC_installation_path is /opt/lgtonmc by default and XX is a number that you specify to create a new subdirectory. For example, if the NMC server uses the default location and the /opt/ lgtonmc/nmcdb1 directory exists, type the following command: /opt/lgtonmc/bin/gstdbinit -U postgres -n 5432 /opt/lgtonmc/nmcdb2
4. Start the NMC database, by typing the following command:
NMC_installation_path/postgres/bin/pg_ctl -D NMC_installation_path/ nmcdbXX/pgdata -l logfile start where: NMC_installation_path is /opt/lgtonmc by default and nmcdbXX is the subdirectory that you created in the previous step. For example, if the NMC server uses the default location and the nmcdb directory nmcdb2, type: /opt/lgtonmc/postgres/11.1/bin/pg_ctl -D /opt/lgtonmc/nmcdb2/pgdata -l logfile start

Updating the NetWorker Management Web UI software The NetWorker Management Web UI, introduced in NetWorker 18.1, is a web-based management interface that provides support for the following NetWorker VMware integrated operations.
Updating the NetWorker Management Web UI software Procedure
1. You can upgrade the NetWorker Management Web UI software by running the NetWorker 19.1 NWUI rpm package.
Host Machine Procedure
NetWorker Server You must run rpm -Uvh lgtonwuiserv-*.rpm from the NetWorker 19.1 package.
Not a NetWorker Server
You must run rpm -Uvh lgtonwui-*.rpm from the NetWorker 19.1 package.
Updating NetWorker on CentOS, OEL, RHEL, and SuSE from NetWorker 8.2.x
Use the following procedures to update the NetWorker and NMC Serversoftware from version 8.2.x.
Preparing the Linux host for a NetWorker software or NMC server software update
Before you update the NetWorker software or NMC server software on Linux, review the following information.
Preparing the NetWorker server Before you update the NetWorker server, ensure that the media database and client file indexes are in a consistent state and that you have a backup of the databases.
To prepare the NetWorker server, perform these steps from a command prompt on the NetWorker server as root on UNIX or administrator on Windows.
Procedure
1. Put the NetWorker databases in a consistent state:
nsrim -X nsrck -m nsrck -L6
2. Record the current location of the NetWorker client file indexes:
nsrls
3. Record the range of ports the NetWorker software uses:
Updating NetWorker for Linux
46 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
nsrports
4. Perform a backup of the bootstrap, the client file indexes, and the resource database, type savegrp -O group_name where group_name is the name of a group that contains all the NetWorker clients in the datazone. If a group that contains all the clients does not exist, run multiple savegrp commands, specifying a different group each time. This will ensure that you back up the clients indexes for each client in the datazone.
Note
Ensure the media pool associated with the group has appendable media available.
5. Record the latest bootstrap save set ID (ssid) including the file number, the record number, and the associated volume label.
For example:
mminfo -B
date time level ssid file record volume 10/11/11 16:29:40 full 4254377781 0 0 bootstrap_vol.001 In this example:
l The save set ID (ssid) is 4254377781.
l The file number is 0.
l The record number is 0.
l The label of the volume that contains the bootstrap save set is bootstrap_vol.001.
NetWorker server only, back up the LDAP or AD configuration If the NetWorker datazone uses LDAP or AD to authenticate access to the NetWorker server and NMC server, create a copy of the configuration file, /opt/nsr/cst/ Config.xml.
SuSE Package Requirements The NetWorker software has OS package dependencies. The default SuSE installation does not contain all the operating system packages that the NetWorker software requires.
When you use the rpm command to install the NetWorker software, the installation displays a list of missing required OS packages. You must install the required packages before you install the NetWorker software.
For example, when you run the rpm command to install the NetWorker software on a default installation, output similar to the following might appear:
rpm -ivh lgtoclnt-19.1-0.x86_64.rpm error: Failed dependencies: libcap.so.1()(64bit) is needed by lgtoclnt-19.1-0.x86_64 libstdc++.so.5()(64bit) is needed by lgtoclnt-19.1-0.x86_64 libstdc++.so.5(CXXABI_1.2)(64bit) is needed by lgtoclnt-19.1-0.x86_64
Updating NetWorker for Linux

l compat-libstdc++-33-3.2.3-68.1.x86_64.rpm l libcap1-1.10-47.1.x86_64.rpm
RHEL 7 and CentOS Package Requirements The NetWorker installation requires some packages that the default OS installation might not include.
Manually download and install the following Linux OS packages. The NetWorker installation fails when these packages do not exist on the host:
l ksh l glibc.i686 0:2.17-55.el7 or later l nss-softokn-freebl.i686 0:3.15.4-2.el7 or later
Note
For PowerPC (PPC) hosts, install the 32-bit Pluggable Authentication Modules (PAM) library, pam-1.1.8-12.el7_1.1.ppc or later, on the host. NetWorker requires the 32-bit package, even when the 64-bit PAM package exists on the host.
Updating the NetWorker software You can use the rpm -U command to update the NetWorker client, server, and storage node software without first removing the previous version of the software.
Before you begin
Before you remove the NetWorker software, remove the NetWorker module software. The NetWorker module software includes the NetWorker Module for Database Applications software. The appropriate module installation guide describes how to uninstall the module software.
Before you start the NetWorker Server update, install the Java provided in NetWorker Runtime Environment or the latest version of the 64-bit Java 8 on the host. Before you install the Java software, stop NMC and any running NetWorker Server daemons.
Note
If the NetWorker server is also the NMC server, use the procedure described in Updating the NMC server on page 41 to update the NetWorker server.
Procedure
1. Download the NetWorker software package from the Online Support website to a temporary location.
Ensure that there is sufficient disk space on the host.
2. Change to the temporary location that contains the software package, and then unzip and extract the files by typing the tar command.
For example:
Updating NetWorker for Linux
48 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
tar -xzf file_name.tar.gz
3. Stop the NetWorker service.
4. Use the rpm -qa | grep lgto command to display the list of installed NetWorker packages.
5. From the directory that contains the latest version of extracted NetWorker software packages, type:
rpm -Uvh package [package]... where:
l package [package]... is a list of the software package for the installation type.
Note
The Block-Based Backup (BBB) package requires a different command. Do not include the package in the update command.
l You specify optional packages such as language packs and man pages in rpm command after the required packages for the installation type.
l You can use the rpm -U command to install new NetWorker package, for example the Extended Client software and the NetWorker Authentication Service software.
This table provides a list of the software packages that you are required to specify for each installation type.

6. After you update the NetWorker software, it is recommended that you delete the contents of the /nsr/tmp directory.
7. For a NetWorker server only, configure the NetWorker Authentication Service:
a. To start the NetWorker Authentication Service configuration script, type/opt/nsr/authc-server/scripts/authc_configure.sh.
b. At the Specify the directory where the Java Standard Edition Runtime Environment software is installed prompt, Press Enter to accept the default location, /opt/nre/java/latest.
c. The configuration process uses port 9090 for communication. If the configuration process detects that the port is in use, a warning similar to the following appears: Warning: Port 9090 is already in use.
Perform the following steps to specify a different port.
a. At the Do you wish to specify a different port number prompt, press Enter to accept the default response, Yes.
b. At the Specify the port that Apache Tomcat should use for communication? prompt, specify the port number.
Note
Valid port numbers are between 1024 and 49151. If the configuration process detects that the port that you specified is in use, a prompt asks if you want to select a different port number.
d. At the Specify the keystore password prompt, type the keystore password.
Specify a password that contains at least six characters and does not contain dictionary words.
e. At the Confirm the password prompt, type the keystore password.

g. At the Confirm the password prompt, type the password for the administrator account.
8. Start the NetWorker daemons: /etc/init.d/networker start When you start the NetWorker daemons on a NetWorker server, the process will migrate some NetWorker 8.2 resource attributes values to create new NetWorker 19.1 resources. The chapter Reviewing the Migration Status provides more information about how to review the results of the migration process.
9. Confirm that the NetWorker daemons have started, by typing the command below, based on the initialization system running on your Linux machine :
l sysvinit/etc/init.d/networker status l systemdsystemctl status networker
For a NetWorker server, the nsrctld daemon starts. The nsrctld daemon starts other processes that the NetWorker server requires. Output similar to the following example appears when the daemons are started:
+--o nsrctld (29021) +--o epmd (29029) +--o rabbitmq-server (29034) +--o beam (29038) +--o inet_gethost (29144) +--o inet_gethost (29145) +--o jsvc (29108) +--o jsvc (29114) +--o nsrd (29123) +--o java (29135) +--o nsrmmdbd (29828) +--o nsrindexd (29842) +--o nsrdispd (29853) +--o nsrjobd (29860) +--o nsrvmwsd (29968) +--o eventservice.ru (29154) +--o jsvc (29158) +--o jsvc (29159) +--o java (29838) +--o node-linux-x64- (29885) +--o nsrexecd (29004) +--o nsrlogd (29899) +--o nsrsnmd (30038)

Results
The startup process migrates the NetWorker Server media database to a new format. Messages similar to the following appear in the daemon.raw file when the migration completes successfully:
NSR Media database completed extended consistency checks. NSR Original media database has been renamed to 'NetWorker_installation_directory/mm/mmvolume6.Aug_11_15
Note
Do not perform any NetWorker commands while the media database conversion is in progress. The migration might fail and messages similar to the following appear in the daemon.raw:
NSR info Migration unsuccessful: Unable to rename original media database 'NetWorker_installation_directory\mm\mmvolume6': The process cannot access the file because it is being used by another process. (Win32 error 0x20)
If the migration fails, stop the NetWorker command, then stop and restart the NetWorker Server daemons to perform the media database conversion again.
If you update a NetWorker Server that is also the NMC Server and the update procedure fails, review the daemon.raw file to determine if the migration completed.
Updating the NMC server The NMC server uses the NetWorker Authentication Service on the NetWorker server for user access and user management. Before you update the NMC server, ensure that you update the NetWorker server software and start the NetWorker daemons on the NetWorker server.

The NetWorker E-LAB Navigator provides the latest information on supported NMC server operating systems.
Preparing the NMC server Before you update the NMC server software from an 8.1.x or 8.2.x release, perform a manual backup of the NMC server database, and then convert the NMC database.
Performing a manual backup of the NMC database
Perform the following steps to back up the NMC database.
Procedure
1. Set the LD_LIBRARY_PATH environment variable to NMC_install_dir/ lgtonmc/bin:NMC_install_dir/sybasa/lib.
The default NMC installation directory is /opt/lgtonmc 2. Use the savepsm command to perform the backup.
savepsm -I "NMC_install_dir" -b pool_name
where NMC_install_dir is the NMC server installation directory.
Updating NetWorker for Linux
Updating the NMC server 53
Note
If the installation directory path contains spaces, then enclose the path in quotations.
The NetWorker Command Reference Guide or the UNIX man pages provides information about the savepsm command.
Preparing the NMC database
The NMC database in 19.1 is a Postgres database. NetWorker server 8.2.x and earlier uses a Sybase database.
Perform the following steps to convert the Sybase database into an Unload Database. The upgrade process will prompt you for the location of the converted files, and then import the Unload Database into a Postgres database.
Note
To update the NMC server without converting the database, use the touch command to create the /opt/lgtonmc/logs/dbunloaded.tag file.
Procedure
1. Stop the NetWorker and NMC daemons, by typing the command below, based on the initialization system running on your Linux machine:
Initialization system Command
sysvinit /etc/init.d/networker stop
systemd systemctl stop networker
Initialization system Command
sysvinit /etc/init.d/gst stop
systemd systemctl stop gst
2. Copy the gstdbunload file from the directory to which you extracted the NetWorker 19.1 software, into the installation_path/bin folder on the NMC server. By default, the installation_path is in the following location:
l AIX, HP-UX, and Linux: /opt/lgtonmc l Solaris: /opt/LGTONMC
3. Create a directory that will contain the Unload Database files. Specify a location that has sufficient disk space to store the converted database. To store the Unload Database files, the conversion process requires free disk space equal to 1.5 times the size of the original database.
Updating NetWorker for Linux
54 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
Note
The update process creates a new user for the Postgres database, and uses this new user to read the contents of the directory that contains the Unload Database. Ensure that everyone has execute level permissions to the directory and the directory contents.
4. From a command prompt, in the installation_path/bin folder, type the following command:
./gstdbunload target_conversion_dir
where target_conversion_dir is the directory that you created in the previous step.
Note
If the the NMC daemons are running the database conversion process fails with an error messages similar to the following :
SQL error: Unable to start specified database: autostarting database failed. 139495:gstdbunload: Database unload failed. Please check /target_conversion_directory/ reload.log for any reported errors.
To resolve this issue, stop the NMC daemons and run the gstdbunload command again.
The status of the conversion appears in stdout and in the target_conversion_dir/reload.log file.
5. For pre-19.1 Solaris, HP-UX, and AIX NMC servers only, copy the target_conversion_dir to the target Windows or Linux NMC server.
Updating the NMC server software Use the rpm -U command to update the NMC server software without first removing the previous version of the software.
Procedure
1. Use the rpm -qa | grep lgto command to display the list of installed NetWorker packages.
2. From the directory that contains the latest version of extracted NetWorker software packages, type:
rpm -Uvh lgtoclnt-*.rpm lgtonmc*.rpm package [package]...
where package [package]... is a list of NetWorker 8.2.x optional software packages or additional NetWorker 19.1 packages.
For example:
l To update the NMC server, and install the optional man pages and install the Extended Client software, type:
rpm -Uvh lgtoclnt-*.rpm lgtonmc*.rpm lgtoman*.rpm lgtoxtclnt*.rpm
Updating NetWorker for Linux
Updating the NMC server 55
l To update an NMC server that is also the NetWorker server, type:
rpm -Uvh lgtoclnt-*.rpm lgtonode*.rpm lgtoxtclnt*.rpm lgtoauthc*.rpm lgtoserv*.rpm lgtonmc*.rpm lgtoman*.rpm
Note
A message similar to the following might appear during the update process: lgto_gst" deleted from file /root/.odbc.ini This is expected behavior and an informational message only.
3. When the NMC server is also the NetWorker server, perform the following steps to configure the NetWorker Authentication Service:
a. To start the NetWorker Authentication Service configuration script, type/opt/nsr/authc-server/scripts/authc_configure.sh.
b. At the Specify the directory where the Java Standard Edition Runtime Environment software is installed prompt, Press Enter to accept the default location, /opt/nre/java/latest.
c. At the Specify the keystore password prompt, type the keystore password.
Specify a password that contains at least six characters and does not contain dictionary words.
d. At the Confirm the password prompt, type the keystore password.
e. At the Specify an initial password for administrator prompt, type a password for the administrator user account. You will use this password to log in to the NMC Server.
Ensure the password complies with the following minimum requirements:
l Nine characters long
l One uppercase letter
l One lowercase letter
l One special character
l One numeric character
Note
You will use the administrator account to log in to the NMC Server.
f. At the Confirm the password prompt, type the password for the administrator account.
4. Start the NetWorker daemon on the Linux host:
/etc/init.d/networker start
Updating NetWorker for Linux
56 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
Configuring the NMC server When you update from 8.2.x, use the nmc_config command to configure the NMC server software and convert the NMC database from Sybase to Postgres.
Before you begin
Before you start the NMC configuration script, ensure that the nsrexecd daemon is running on the NMC host and the NetWorker daemons are running on the NetWorker Server. Use the /etc/init.d/networker status command in sysvinit or systemctl status networker in systemd to confirm that the daemons are started. If required, use the /etc/init.d/networker start command in sysvinit or systemctl start networker in systemd to start the NetWorker daemons. The configuration requires communication with processes on the NetWorker Server. When the NMC Server is not the NetWorker Server, ensure that the NMC Server can communicate with the NetWorker Server. Procedure
1. Start the configuration script, by typing the following command:
/opt/lgtonmc/bin/nmc_config
2. If the NetWorker services are not started on the NMC Server, the NetWorker services are not running on this host. Do you want to start them now? prompt appears. To start the NetWorker services, press Enter.
3. From the Specify the directory to use for the NMC database prompt, specify a path or press Enter to accept the default path /nsr/nmc/ nmcdb.
4. For updates from NMC 8.2.x, perform the following steps:
a. On the Do you want to migrate data from a previous LGTOnmc 8.x.x. release prompt, type y.
b. On the Specify the directory that contains the unloaded data prompt, specify the path to the directory that contains 8.x.x conversion files that are created by the gstdbunload command.
5. From the Specify the host name of the NetWorker Authentication Service host prompt, specify the name of the NetWorker Server that you want to use for NMC and NetWorker Server user authentication.
Note
If the configuration script does not detect the NetWorker Authentication Service on the host that you specified, or the authentication service does not use the default port 9090, a warning message appears. The configuration script prompts you to specify a different authentication server host. Type Y and when prompted, type the hostname and port of the NetWorker Authentication Service host.
6. When prompted to start the NMC Server daemons, type y.
7. Confirm that the daemons have started, by typing the following command: ps -ef | grep lgtonmc.
Output similar to the following appears when the daemons have started:

CHAPTER 4
Updating NetWorker for Windows
This chapter describes how to update the NetWorker software for Windows and includes the following topics:
l Updating NetWorker from 8.2.x on Windows.....................................................66 l Updating NetWorker from 9.x on Windows........................................................82 l Updating the NetWorker Management Web UI software................................... 95
Updating NetWorker for Windows 65
Updating NetWorker from 8.2.x on Windows Use the following procedures to update the NetWorker or NMC Server software.
l Updating the NetWorker software on page 66
l Updating the NMC server software on page 74
Note
If the NetWorker Server and the NMC Server are on different hosts, you must update NetWorker on the NetWorker Server host before the NMC Server host.
Updating the NetWorker software Follow these procedures to update the NetWorker software, which includes the NetWorker Server, Storage Node, and Client.
Note
The update process will only update existing NetWorker components. You cannot change the installation type during an update. The NetWorker Installation Guide describes how to change the installation type and how to add additional NetWorker components.
Updating the NetWorker Server from 8.2.x Follow these procedures to prepare and then update the NetWorker Server.
Preparing the NetWorker server
Before you update the NetWorker server, ensure that the media database and client file indexes are in a consistent state and that you have a backup of the databases.
To prepare the NetWorker server, perform these steps from a command prompt on the NetWorker server as root on UNIX or administrator on Windows.
Procedure
1. Put the NetWorker databases in a consistent state:
nsrim -X nsrck -m nsrck -L6
2. Record the current location of the NetWorker client file indexes:
nsrls
3. Record the range of ports the NetWorker software uses:
nsrports
4. Perform a backup of the bootstrap, the client file indexes, and the resource database, type savegrp -O group_name where group_name is the name of a group that contains all the NetWorker clients in the datazone. If a group that contains all the clients does not exist, run
Updating NetWorker for Windows
66 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
multiple savegrp commands, specifying a different group each time. This will ensure that you back up the clients indexes for each client in the datazone.
Note
Ensure the media pool associated with the group has appendable media available.
5. Record the latest bootstrap save set ID (ssid) including the file number, the record number, and the associated volume label.
For example:
mminfo -B
date time level ssid file record volume 10/11/11 16:29:40 full 4254377781 0 0 bootstrap_vol.001 In this example:
l The save set ID (ssid) is 4254377781.
l The file number is 0.
l The record number is 0.
l The label of the volume that contains the bootstrap save set is bootstrap_vol.001.
NetWorker server only, back up the LDAP or AD configuration If the NetWorker datazone uses LDAP or AD to authenticate access to the NetWorker server and NMC server, create a copy of the configuration file, C:\Program Files \EMC NetWorker\nsr\cst\Config.xml.
Updating the NetWorker server software
You can use the NetWorker-19.1.exe to update the NetWorker Server software without first removing the previous version of the software. When you install the NetWorker Server software, the installation also installs the NetWorker Client, Storage Node, BBB, NetWorker Authentication Service, and Extended Client software.
Before you begin
Before you start the NetWorker Server installation, install the Java provided in NetWorker Runtime Environment or the latest version of the 64-bit Java 8 on the host. All the clone names that use special characters must be changed to alphanumeric characters.
If the NetWorker Server is also the NMC server, update both options at the same time. Updating the NMC server on a NetWorker server describes how to update the NetWorker Server and NMC server software on the same host.

Updating the NMC server software Use the NetWorker-19.1.exe file to update the NMC server software and import the NMC database to the new Postgres format. When you update the NMC server software, the updating process will also update the NetWorker software.
Performing a manual backup of the NMC database Perform the following steps to back up the NMC database.
Procedure
1. Connect to the NetWorker server with the administrator account, and then open a command prompt.
2. Use the savepsm command to perform the backup.
savepsm -I "NMC_install_dir" -b pool_name
where NMC_install_dir is the NMC server installation directory.
Note
If the installation directory path contains spaces, then enclose the path in quotations.
The NetWorker Command Reference Guide or the UNIX man pages provides information about the savepsm command.
Optional, manually migrating the NMC database The NMC database in 19.1 is a Postgres database. NetWorker server 8.2.x and earlier uses a Sybase database.
When you update a Windows NMC server, it is recommended that you allow the migration process to handle the database migration. If your 8.2.x NMC Server is on a Windows operating system that NetWorker 19.1 does not support, you must use the gstdbunload utility included with the NetWorker 19.1 software package to convert the NMC database into a platform independent format. After you convert the database, you must copy the converted files to the Windows or Linux host that will become the new NMC Server. Perform the following steps to convert the Sybase database into an Unload Database. The upgrade process will prompt you for the location of the converted files, and then import the Unload Database into a Postgres database.
Procedure
1. Stop the NetWorker and NMC services.
2. Copy the gstdbunload file from the directory to which you extracted the NetWorker 19.1 software, into the installation_path\bin folder on the NMC server.
Updating NetWorker for Windows
74 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
By default, the installation_path is C:\Program Files\EMC NetWorker \Management\GST.
3. Create a directory that will contain the Unload Database files. Specify a location that has sufficient disk space to store the converted database. To store the Unload Database files, the conversion process requires free disk space equal to 1.5 times the size of the original database.
Note
The update process creates a new user for the Postgres database, and uses this new user to read the contents of the directory that contains the Unload Database. Ensure that everyone has execute level permissions to the directory and the directory contents.
4. From a command prompt, in the installation_path\bin folder, type the following command: gstdbunload target_conversion_dir where target_conversion_dir is the directory that you created in the previous step.
Note
If the the NMC daemons are running the database conversion process fails with an error messages similar to the following :

l Updating the NMC server on page 89
Note
If the NetWorker Server and the NMC Server are on different hosts, you must update the NetWorker software on the NetWorker Server host before the NMC Server host.
Updating the NetWorker software
On Windows, the procedure to update the NetWorker software depends on the version you are updating to and from.
Each NetWorker version consists of numerical values in the following versioning schema: major.minor.service_pack.hotfix. For example, the 6th cumulative build of NetWorker 9.1 is 9.1.0.6
Consider the following scenarios:
l When you update from a version of the NetWorker software that shares the same service pack number as the newer software version, first remove the older version of the NetWorker software. Once removed, install the new version of the NetWorker Server software. For example:
n When you want to update a NetWorker host from NetWorker 9.1 (9.1.0.0) to cumulative hotfix version 9.1.0.6.
n When you want to update a NetWorker host from cumulative hotfix version 9.1.0.1 to 9.1.0.6.
The NetWorker Installation Guide describes how to remove the previous version of the NetWorker software and install the new version.
Updating NetWorker for Windows
82 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
l When you update from a version of the NetWorker software that does not share the same service pack number as the newer version, you can use the installation command to update the NetWorker software, without first removing the previous version of the software. For example, when you want to update from NetWorker cumulative hotfix version 9.0.1.0 to NetWorker 9.2. (9.2.0.0).
To update the NetWorker software on a host to a version that does not share the same service pack number, review the following sections.
Note
The update process will only update existing NetWorker components. You cannot change the installation type during an update. The NetWorker Installation Guide describes how to change the installation type and how to add additional NetWorker components.
Follow these procedures to update the NetWorker software or the NMC Server software.
l Updating the NetWorker server software from 9.x on page 83
l Updating the NetWorker storage node software on page 70
l Updating the NetWorker Client software on page 71

Preparing the NetWorker server
Before you update the NetWorker server, ensure that the media database and client file indexes are in a consistent state, and that you have a backup of the databases.
Procedure
1. Connect to the NetWorker server as root on UNIX and administrator on Windows, and then open a command prompt.
2. Put the NetWorker databases in a consistent state:
nsrim -X nsrck -m nsrck -L6
3. Record the current location of the NetWorker client file indexes:
nsrls
4. Record the range of ports the NetWorker software uses:
nsrports
5. Perform a server backup by starting the Server backup workflow.
Ensure that the media pool associated with the backup action has appendable media available.
6. Record the latest bootstrap save set ID (ssid) including the file number, the record number, and the associated volume label.
For example:

Updating NetWorker Clients by using the Package Manager Feature 117
Introduction Package Manager is a feature that provides you with the ability to centrally manage software updates of the NetWorker software, including the NetWorker Module for Microsoft (NMM), NetWorker Module for SAP (NMSAP), and NetWorker Module for Database Applications (NMDA) software. In previous versions of the NetWorker software, this feature was also known as Client Push.
There are four main components of the Package Manager feature:
l Media Kit LocationA directory on a host that contains the source NetWorker software packages.
l Software repositoryA local directory on the NetWorker server that contains a copy of the NetWorker software packages from the Media Kit Location.
l Target hostsNetWorker hosts in the datazone that has a NetWorker software or module software version that supports a Package Manager update.
The following image provides a high level overview of how to use the Package Manager feature to update the NetWorker software on hosts in a datazone:
Figure 3 Package Manager overview
In this image, the following steps are performed:
1. Add the software to the Software Repository from the Media Kit Location.
2. Perform an inventory operation of the NetWorker hosts in the datazone, to gather information about the installed NetWorker software and NMDA software.
3. Push software updates to eligible target hosts.

Updating NetWorker Clients by using the Package Manager Feature
Package Manager requirements 119
Updating NetWorker by using Package Manager Use the software distribution feature, Package Manager, to update the NetWorker, NMM, NMSAP, and NMDA module software on NetWorker hosts in the datazone from the NetWorker server.
When you use this feature, you are not required to log in to each host manually to uninstall the old NetWorker software version, and then install the new NetWorker software version.
Preparing the Media Kit Location The Media Kit Location contains the source NetWorker software packages that are used to update the NetWorker target hosts. You can specify a Media Kit Location, which is a directory that contains the extracted software packages. Ensure that the path to the Media Kit Location does not contain spaces or the following special characters: ) ( , ' If you place multiple versions of the NetWorker software in the Media Kit Location, create separate subdirectories for each version to avoid overwriting files and directories.
Preparing the software repository Before you can use Package Manager to update the NetWorker software, add the information about the NetWorker packages from the Media Kit Location into the Package Manager software repository database.
Use the Hosts Task window in NetWorker Administration or the nsrpush program to prepare the software repository database.
Adding software to the repository by using the Hosts Task window Use the Hosts Task window in NMC to add software to the Package Manager software repository.
Before you begin
By default, NetWorker creates a directory in the default NetWorker installation location on the NetWorker server for the repository location. To use another location, create the directory before you perform the following steps.
Procedure
1. Login to the NMC server with a user that is both an NMC administrator and a member of the Application administrators user group on the NetWorker server.
2. Use NMC to connect to the NetWorker server.
3. On the EMC NetWorker Administration window, click Hosts.
The Hosts Task window appears with the Known Hosts button selected. The Known Hosts view provides a list of NetWorker hosts configured on the NetWorker server.
4. Click Software Repository.
The Repository window pane appears.
5. Right-click an empty area of the Repository window pane, and then select Add to repository.

where:
l Product_Name is the name of the product:
n NetWorker
n NetWorker Module for SAP
n NetWorker Module for Databases and Applications
Note
Product names are case sensitive and ensure that you enclose the module product names in quotation marks (" ").
l version is the version of the software product, for example, 19.1.
l platform is the operating system platform of the package, for example: win_x64 or linux_x86_64.
l -R repo_location specifies the path to the repository. When you do not specify the -R option, the repository is created in the following default locations:
n On Linux:/nsr/repository.
n On Windows: NetWorker_install_dir\repository l -U specifies a UNIX media kit and -W specifies a Windows media kit. Use the
appropriate option for the package that you want to add to the repository.
l -m media_kit_location is the path to the media kit.
Inventorying the target hosts for installed products Before you can update the NetWorker software on a host, you must inventory the host to determine the installed versions of NetWorker software.
Use the Hosts Task window in NMC or the nsrpush program to inventory the target hosts.
Inventorying installed products by using NMC Use Software Inventory in Hosts Task window to generate an inventory of the NetWorker software that is installed on the target hosts.
Procedure
1. On the NetWorker Administration window, click Hosts.
2. Select the hosts to inventory. Use the Control or Shift key to select multiple hosts. Right-click and select Perform Inventory.
The Software Operations window pane provides the status of the inventory job. When you inventory many clients, the operation might take awhile to complete.
If the inventory operation fails, perform one of the following:
Updating NetWorker Clients by using the Package Manager Feature
122 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
l Review the nsrcpd.raw file, located in the NetWorker_installation_dir/logs directory on the NetWorker server.
l Right-click the failed operation and select Restart to re-attempt the inventory.
3. Click Software Inventory.
The Software Inventory window pane displays information about the NetWorker software that is installed on known hosts in the datazone. The following figure provides an overview of the NetWorker, NMDA, and NMM software that is installed on the inventoried hosts. Figure 4 Software Inventory window
Inventorying installed products by using nsrpush Use the nsrpush command to generate an inventory of the NetWorker, NMDA, and NMSAP software that is installed on the target hosts.
To inventory hosts configured on the NetWorker server, type one of the following commands:
nsrpush -i -all nsrpush -i hostname1...hostnameX nsrpush -i -f hostname_file
where:
l -all queries and inventories every NetWorker client in the datazone.
l hostname1...hostnameX is a space-separated list of hostnames to inventory in the datazone.
l hostname_file is a text file that contains a list of the hostnames to inventory. Specify one hostname on each line.
Querying hosts for installed products
To query a host for a list of installed NetWorker products, type one of the following commands:
nsrpush -s [-t] -all nsrpush -s [-t] hostname1...hostnameX nsrpush -s [-t] -f hostname_file
where:
l -t is optional and when specified, displays the output in tabular format.
l -all queries each inventoried client.

l hostname_file is a text file that contains a list of hostnames to query. Specify one hostname on each line.
Updating NetWorker Clients by using the Package Manager Feature
Inventorying the target hosts for installed products 123
Updating all hosts on the NetWorker server After you add a NetWorker host to the Package Manager inventory, use the Hosts Task window in NMC or the nsrpush program to update the NetWorker host with a newer package that is stored in the software repository.
Updating NetWorker products on a user-specified host by using the NMC You can use the Package Manager to update the NetWorker software on certain hosts in a datazone.
Before you begin
Perform a client inventory operation before you upgrade the software on the client to ensure that NetWorker has an accurate inventory of the software that is installed on a host.
Procedure
1. On the Software Inventory view, select each host that you want to update. Use the Ctrl or Shift key to select multiple hosts.
2. Right-click and select Upgrade software.
3. In the pop-up window, click Yes, Continue to perform the software upgrade.
4. On the Upgrade Software window, a list of hosts and the installed products that are eligible for update appear. Select the hosts and products, and then click Upgrade.
When you update an NMDA or NMM client, you must update module and NetWorker products simultaneously. To select multiple products, hold the Ctrl key while you select a product.
5. On Monitor Activity window, review the status of the selected update job in the upper table and the status of each client update operation in the lower pane.
Note
The update operation performs software updates on each client sequentially and as a result an update job with many clients might take a while to complete. For example, a client update operation usually takes between 1-3 minutes. To update 300 clients, the update operation might take 5-10 hours or longer to complete.
If the update operation fails, review the NetWorker_Installation_dir/ nsrcpd.raw file on the NetWorker server for error messages. To try the update again, select the failed operation, and then click Retry client job.
6. Click Finish.
Updating NetWorker products on a user specified host by using the nsrpush command Use the nsrpush command to update the NetWorker software on certain hosts in a datazone.
Log in to the NetWorker server with the root user on UNIX or the administrator user on Windows and then type one of the following commands to update all inventoried hosts or selected hosts of the NetWorker server:
nsrpush -u -p product -v version [-Tp directory] [-To timeout] -all nsrpush -u -p product -v version [-Tp directory] [-To timeout]

To resolve this issue, provide the admin user on the NMC Server access to the NetWorker Server by typing the following command from a command prompt on the NetWorker Server:
nsraddadmin -u "user=username, host=NMC_server_hostname
Updating NetWorker Clients by using the Package Manager Feature
Troubleshooting Package Manager 125
Package manager inventory or update fails If the inventory or update operation fails, perform the following tasks.
l Try the inventory or update operation with the nsrpush command, which might provide more detailed errors messages and might make the cause of the failure more clear
l Review the contents of the nsrcpd.raw log for details. The default log location differs on windows and Linux:
n Windows: C:\Program Files\EMC NetWorker\nsr\logs\nsrcpd.raw n Linux: /nsr/logs/nsrcpd.raw
Updates performed with Package Manager time out By default each update operation is allocated 10 minutes to complete and an upgrade will usually complete in 1-3 minutes.
Some Windows clients might require additional time when multiple packages are being upgraded or when the network is slow. To allocate more time to the update process, use the -To option with the nsrpush command.
No available products were found for the selected clients in the software repository
This error message appears during an update operation in the following scenarios.
l When the software repository does not contain any software packages.
l When the required software is not in the software repository.
l When the version in selected client is more recent than the product version in the repository.
To resolve this issue, add software packages to the repository and ensure version compatibility.
NSR warning: Remote error running inventory scripts on client This error message appears when you try to update a Linux host that does not support software installation by using .rpm files, for example Ubuntu or Debian.
To resolve this issue, manually update Linux clients with operating systems that do not support .rpm files.
uasm: Unable to read checksum from save The following messages appear in the nsrpcd.raw file when Package Manager is unable to copy the installation package to the target host due to network bandwidth issues or high load on the host.
nsrcpd Retrying file send for 'C:\Legato\nsr\repository \NetWorker-19.1.0.1-win_x64\NetWorker.cps' due to 1 failure(s).
nsrrcopy failed with code 1. 5041:uasm: Unable to read checksum from save stream
Package Manager will retry the copy operation up to three times, and reports the number of blocks that are successfully sent to the client in the nsrcpd.raw file.
Updating NetWorker Clients by using the Package Manager Feature

For example:
nsrcpd Sent 20000 x 1024 byte blocks. nsrcpd Sent 30000 x 1024 byte blocks.
When the entire copy operation completes successfully, a message similar to the following appears:
nsrcpd File send succeeded after retry
If the copy operation does not complete successfully, retry the update operation at a time when there is sufficient network bandwidth to complete the file copy operation or when the host is idle.
NetWorker Server lacks sufficient file space to store repository in the default location
The Package Manager software repository stores copies of NetWorker packages. The NetWorker Server requires about 1 GB of free disk space for each stored package. If a large number of packages are in use or if the default location has limited available disk space, you can relocate the repository or remove packages from the repository. To change the repository location or remove software packages from the repository, use the Host Task window or the nsradmin program.

Post Update Tasks
After you update the NetWorker and NMC Servers, review this chapter to ensure that you can connect to the NMC Server. If you updated the NetWorker software from 8.1.x or 8.2.x, this section provides detailed information about changes that occur in the NetWorker software.
This chapter contains the following topics:
l Verifying the variables in nssrc file....................................................................134 l Preparing to connect to the NMC server..........................................................134 l Improve clone performance.............................................................................. 136 l After upgrading from 8.2.x............................................................................... 136
Post Update Tasks 133
Verifying the variables in nssrc file Post upgrade, you must verify that the variables NSR_SHOW_LEGACY_DEVICES and NSR_SHOW_FSC_DEVICES are set to yes in the /nsr/nsrrc file.
Preparing to connect to the NMC server You cannot connect to the NMC GUI with any of the following, previously supported, operating systems:
l AIX
l HP-UX
l Solaris
Before you try to connect to the NMC server from a supported host, ensure that JRE is correctly configured.
Note
Post-upgrade, the maximum heap memory configuration resets to default minimum value of the NetWorker. For information on configuration for the scaled setup, see the Performance Optimization Planning Guide.
Clearing the Java cache Before you update the NMC server, review this section for information about NMC clients and how to clear the java cache.
The NMC server update process replaces the gconsole.jnlp file in the Java web Start cache on the NMC server. As a result, after an NMC server update, the NMC client fails to start the NMC GUI with an error message similar to the following:
Unable to launch NetWorker Management Console To prevent this issue, on each host that you use as an NMC client, clear the local java cache. This workaround enables the NMC client to download the new gconsole.jnlp file from the NMC server.
The procedure is different for UNIX and Windows.
Note
To clear the java cache for NetWorker Runtime Environment, see NetWorker Runtime Environment Readme Guide
UNIX Console client Use the following procedure to clear the java cache on a UNIX Console client.
Procedure

Configuring the NMC server to manage additional NetWorker servers The NMC Server can use only one NetWorker Authentication Service to provide authentication services. When the NMC Server manages more than one NetWorker Server, configure a trust between each NetWorker Server that the NMC Server will manage and NetWorker Server that will provide authentications services to the NMC Server. After you establish each trust, update the user groups on each NetWorker Server to include the users and groups that require access to the NetWorker Server.
Procedure
1. To establish the trust, type the following command on each NetWorker Server that is not local to the NetWorker Authentication Service that NMC uses for authentication:
nsrauthtrust -H Authentication_service_host -P Authentication_service_port_number
where:
l The location of the nsrauthtrust command differs on Linux and Windows:
n Linux/usr/sbin n WindowsC:\Program Files\EMC NetWorker\nsr
l Authentication_service_host is the hostname of the NetWorker Server that authenticates the NMC Server host.
l Authentication_service_port_number is the port number used by the NetWorker Authentication Service. The default port number is 9090.
For example:
nsrauthtrust -H nwserver.corp.com -P 9090
2. Grant the NetWorker Authentication Service user groups access to the NetWorker Server, by typing the nsraddadmin command:
nsraddadmin -H Authentication_service_host -P Authentication_service_port_number
For example:
nsraddadmin -H nwserver.corp.com -P 9090
The nsraddadmin command updates the following user groups:
l Application AdministratorAdds the distinguished name (DN) of the NetWorker Authentication Service Administrators group.
l Security AdministratorAdds the DN of the NetWorker Authentication Service Administrators group.
Post Update Tasks

l UsersAdds the DN of the NetWorker Authentication Service Users group.
3. (Optional) To add other users or groups from the NetWorker Authentication Service to the Application Administrator and Security Administrator user groups on the NetWorker Server, you must determine the DN for the user or group, and then use the nsraddadmin command with the -e option to add the user or group.
For example, to add a user to the Application Administrator and Security Administrator user groups on the NetWorker Server, perform the following steps:
a. Use the authc_mgmt command with the -e find-all-users option to display a list of users and the associated user ID in the local user database:
authc_mgmt -u administrator -p password -e find-all-users The query returns 2 records. User Id User Name 1000 administrator 1001 Patd
Note
The location of theauthc_mgmt command differs on Linux and Windows:
l Linux/opt/emc/authc/bin l WindowsC:\Program Files\EMC\Authc\bin
b. Use the authc_mgmt command with the -e find-user option to display user details for the administrator account, including the user DN:
authc_mgmt -u administrator -p password -e find-user -D user- id=user_id
where user_id is the user ID value for the Patd account.
For example:
authc_mgmt -u administrator -p 1.Password -e find-user -D user-id=1001
User Id : 1001 User Name : Patd User Domain : User First Name: Patrick User Last Name : Dunn User Email : Patd@local User Details : User DN : cn=Patd,cn=Users,dc=bu- iddnwserver2,dc=IddLab,dc=local User Enabled : true User Groups : [100, 101]
c. Use nsraddadmin command to add the user DN of the administrator account to the Application Administrators and Security Administrators user group on each remote NetWorker Server, that the NMC Server manages:
nsraddadmin -e user-dn

Configuring Force Backup Level NetWorker 8.1.x and 8.2.x provided the Force incremental option in the Group resource. The option provided you with the ability to schedule multiple backups for clients in a 24 hours period, but limit the number of full backups to the first scheduled backup. Each subsequent backup in the 24 hour period is an incremental backup. NetWorker 19.1 provides you with the ability to define a backup level for a backup action that differs from the scheduled level. NetWorker 19.1 does not migrate the value in the Force incremental option to the action resource.
For workflows that have more than one scheduled backup within a 24-hour period, use the Force Backup Level attribute to allow more than one backup to occur at two different backup levels in a 24-hour period. When you select a backup level in the Force Backup Level attribute, the first backup is performed at the scheduled backup level. Each subsequent occurrence of the backup action in the next 24 hours occurs at the level defined in the Force Backup Level attribute. For example, if the level defined by the schedule is Full and the Force Backup Level attribute is set to Incr, the first backup started by the action occurs at a level full and subsequent backups, within 24 hours of the start of the full backup are incremental. By default this option is cleared, which means that if the action runs multiple backup operations in a 24 period, all the backups occur at the scheduled backup level.
To define a level for multiple backups that occur in a 24 hour period, perform the following steps:
Procedure
1. In the Administration window, click Protection.
2. In left pane, expand Policies.
3. Expand the policy and then select the workflow.
4. In the Actions pane, right click the action that is schedule to run multiple times in a 24 hour period, and then select Properties.

NetWorker Server and resource migration After upgrading from NetWorker 8.2.x to NetWorker 19.1, when you start the NetWorker processes on the NetWorker Server, the process converts NetWorker 8.2.x resources to the new NetWorker 19.1 policy-based resources.
The following NetWorker 8.2.x resource types do not exist in NetWorker 19.1:
l Group, also referred to as the savegroup or save group
l Schedule clone
l VMware policy
l NAS Device
NetWorker migrates the configuration information for each resource into new resources, which support the NetWorker Data Protection Policy framework.
The migration process creates log files on the NetWorker Server, which provide information about the status of resource conversions. The log files are located in the /nsr/logs/migration folder on LINUX and the C:\Program Files\EMC NetWorker\nsr\logs\migration directory on Windows.
The following table describes the files thatNetWorker creates during the resource migration process.

Overview of protection policies A protection policy allows you to design a protection solution for your environment at the data level instead of at the host level. With a data protection policy, each client in the environment is a backup object and not simply a host.
Data protection policies enable you to back up and manage data in a variety of environments, as well as to perform system maintenance tasks on the NetWorker server. You can use either the NetWorker Management Web UI or the NMC NetWorker Administration window to create your data protection policy solution.
A data protection policy solution encompasses the configuration of the following key NetWorker resources:
Policies Policies provide you with a service-catalog approach to the configuration of a NetWorker datazone. Policies enable you to manage all data protection tasks and the data protection lifecycle from a central location.
Policies provide an organizational container for the workflows, actions, and groups that support and define the backup, clone, management, and system maintenance actions that you want to perform.
Workflows The policy workflow defines a list of actions to perform sequentially or concurrently, a schedule window during which the workflow can run, and the protection group to which the workflow applies. You can create a workflow when you create a new policy, or you can create a workflow for an existing policy.
A workflow can be as simple as a single action that applies to a finite list of Client resources, or a complex chain of actions that apply to a dynamically changing list of resources. In a workflow, some actions can be set to occur sequentially, and others can occur concurrently.
You can create multiple workflows in a single policy. However, each workflow can belong to only one policy. When you add multiple workflows to the same policy, you can logically group data protection activities with similar service level provisions together, to provide easier configuration, access, and task execution.
Protection groups Protection groups define a set of static or dynamic Client resources or save sets to which a workflow applies. There are also dedicated protection groups for backups in a VMware environment or for snapshot backups on a NAS device. Review the following information about protection groups:
l Create one protection group for each workflow. Each group can be assigned to only one workflow.
l You can add the same Client resources and save sets to more than one group at a time.
l You can create the group before you create the workflow, or you can create the group after you create the workflow and then assign the group to the workflow later.
Post Update Tasks
NetWorker Server and resource migration 157
Actions Actions are the key resources in a workflow for a data protection policy and define a specific task (for example, a backup or clone) that occurs on the client resources in the group assigned to the workflow. NetWorker uses a work list to define the task. A work list is composed of one or several work items. Work items include client resources, virtual machines, save sets, or tags. You can chain multiple actions together to occur sequentially or concurrently in a workflow. All chained actions use the same work list.
When you configure an action, you define the days on which to perform the action, as well as other settings specific to the action. For example, you can specify a destination pool, a retention period, and a target storage node for the backup action, which can differ from the subsequent action that clones the data.
When you create an action for a policy that is associated with the virtual machine backup, you can select one of the following data protection action types:
l Backup Performs a backup of virtual machines in vCenter to a Data Domain system. You can only perform one VMware backup action per workflow. The VMware backup action must occur before clone actions.
l Clone Performs a clone of the VMware backup on a Data Domain system to any clone device that NetWorker supports (including Data Domain system or tape targets). You can specify multiple clone actions. Clone actions must occur after the Backup action.
You can create multiple actions for a single workflow. However, each action applies to a single workflow and policy.
The following figure provides a high level overview of the components that make up a data protection policy in a datazone.

Changes to the Client and Pool resources after migration NetWorker uses a number of attributes that are defined in multiple resources to determine which pool receives the data that is generated by an action task, and how NetWorker backs up the data. The migration process preserves the values that are defined for the attributes and introduces new attributes in the Action resource.
NetWorker provides the following attributes, which work together to determine how NetWorker manages a backup and determines which device to use to receive the backup data:
l Client resourcePools, Retention, Save set, and Level attributes on the General tab of the Client Properties window. The migration process retains the values in these legacy attributes.
Note
The Modify Client wizard does not display the Pools, Retention, Save set, and Level attributes.
l Action resourceDestination Pool and Retention attributes on the Specify the Backup Options and Specify the Clone Options wizard windows. The backup levels are defined for the action schedule on the Specify the Action Information wizard window.
l Pool resourceClients, Save sets, and Retention policy attributes on the Legacy tab. The values that appear in these attributes were defined in NetWorker 8.1.x and 8.2.x. After the migration completes, the NetWorker 19.1 server retains the values and these legacy attributes become read-only. You cannot modify the values in these fields after migration.
The Action resource includes an attribute that is called Client Override Behavior. The value that is selected for this attribute determines which resource attribute has precedence over the attributes in other resources that determine the same behavior. By default, the migration process enables Legacy Backup Rules on an Action

resource. Legacy Backup Rules allow NetWorker to use the values during the pool selection criteria process.
Note
By default, the NetWorker Administration window does not show the legacy attributes. To view the legacy attributes in the Client Properties window, go to the View menu and select Diagnostic Mode.
Pre processing and post processing script changes NetWorker 9.0.1 and later does not support the savepnpc command.
After you update the NetWorker server, clients that use savepnpc command to perform backups will fail to backup. Modify these client resources to customize the backup behavior by running pre processing and post processing commands. An error message similar to the following appears in the savepnpc.log file: pstclntsave: RAP query returned NULL worklist. To backup these clients in NetWorker 9.x, edit the Client resource, and perform the following steps:
l In the Backup command attribute, remove the savepnpc command.
l In the Pre command attribute, type the name of the script file that contains the commands to run before the start of the backup.
l In the Post command attribute, type the name of the script file that contains the commands to run after the backup completes.
The section "Backup command customization: in the NetWorker Administration Guide provides more about the Pre command and Post command attributes and how to configure a client that requires pre processing and post processing commands.

Client resource overrides NetWorker 19.1 enables you to define a schedule, destination pool, retention policy, and destination storage node for each backup action that you configure.
NetWorker 8.1.x and 8.2.x allowed you to define a schedule, destination pool, retention policy, and destination storage node value for each Group and Client resource.
When you assigned a value to any of these attributes in the Group resource, that value was applied to all data generated by each client in the group.
When you assigned a value to any of these attributes in the Client resource, that value was applied to all data generated by the client and took precedence over the value that was defined in the equivalent Group resource attribute.
The updating process retains these Client resource values but sets the attributes values to read-only.
The Client resource has the following attributes in common with the Action resource:
Post Update Tasks
162 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
l Schedule
l Pool
l Retention
l Storage Node
The NetWorker 19.1 Action wizard provides you with the ability to define which resource attribute takes precedence, the value that is defined in the Action resource or the value that is defined in a Client resource. The selection that you make in the Client Override Behavior list determines which attribute values take precedence. The following table summarizes each option.
Table 25 Client override behaviors
Option Behavior
Client Can Override The values in the Client resource for Schedule, Pool, Retention policy, and the
Storage Node attributes take precedence over the values that are defined in the equivalent Action resource attributes.
Client Cannot Override The values in the Action resource for the Schedule, Destination Pool, Destination Storage Node, and the Retention attributes take precedence over the values that are defined in the equivalent Client resource attributes.
Legacy Backup Rules This value only appears in actions that are created by the migration process. The
updating process sets the Client Override Behavior for the migrated backup
actions to Legacy Backup Rules.
This value handles the Schedule, Pool, Retention, and Storage Node values in the following way:
l If a value is defined in the Retention Policy attribute of the Group resource,
then the value that is defined in the Retention attribute of the Action resource takes precedence. If a value is not defined in the Group resource, then the attribute that is defined in the Client resource takes precedence.
l If a value is defined in the Schedule attribute of the Group resource, then the
value that is defined in the Schedule attribute of the Action resource takes precedence. If a value is not defined in the Group resource, then the attribute that is defined in the Client resource takes precedence.
l If a value is defined in the Pool attribute of the Client resource, the value that is defined in the Client resource is used. If a value is not defined in the Client resource, then the action sends the data to a pool that best matches the pool selection criteria.
Note
You can edit the Action resource and change the Client Override Behaviour attribute to Client Can Override or Client Cannot Override, but after you save the change to the Action resource, you cannot set the
attribute back to Legacy Backup Rules.
Post Update Tasks
NetWorker Server and resource migration 163
Changes to the schedule resource and levels NetWorker allows you to configure attributes in the Action resource that define the schedule for the task, and for a backup or clone task, the level.
When you configure an Action resource in NetWorker 19.1, the Action wizard provides you with the ability to define the schedule, schedule overrides, and level for the data that is generated by the task.
In NetWorker 8.1.x and 8.2.x, you assigned a pre-configured or user-configured backup schedule to the Group and Client resources. When you assigned the schedule or a level to the Group resource, the values were applied to all the backup and clone data generated by each client in the group. When you assigned the schedule or level to the Client resource, the values were applied to all the backup and clone data generated by the client and took precedence over the values that were defined in the Group resource.
The updating process migrates existing values in the Schedule and Level attributes in the Group resource to the Action resource. NetWorker 19.1 does not support backup levels 29. When the update process encounters a schedule with a backup level 29, NetWorker changes the level to 1. The update process retains the level and schedule attributes that were defined in the Client resource.
The Client resource overrides section describes how NetWorker 19.1 determines the schedule that a task uses when an action is performed on a client and both the Client resource and Action resource define a schedule.
Changes to save set policies NetWorker 19.1 does not separate the length of the browse time for a save set from the length of the retention time for a save set. Information about a backup or clone save set remains in the client file index and media database for the length of time that is defined by the retention policy.
When you configure an Action resource in NetWorker 19.1, the Action wizard provides you with the ability to define the retention policy for the data that is generated by the task.
In NetWorker 8.1.x and 8.2.x, you assigned a browse and retention policy to the Group and Client resources. When you assigned a browse or retention policy to the Group resource, the value that is applied to all the data that is generated by each client in the group. When you assigned a policy to the Client resource, the value that is applied to all the data that is generated by the client.
The updating process performs the following tasks:
l Migrates the existing value in the Retention Policy attribute in the Group resource to the Action resource.
l Modifies the browse time for all save sets in the media database to match the retention time.
l Modifies the Browse policy in the Client resource to match the existing value in the Retention Policy attribute, and make the attribute read-only.
l Retains the value that is defined in the Retention Policy attribute that was defined in the Client resource. The Client resource overrides section describes how NetWorker 19.1 determines the retention policy that a task uses when an action is performed on a client and both the Client resource and Action resource define a retention policy.

Changes to the save set expiration process NetWorker 19.1 expires save set information in the media database and client file index as a separate action, in the Server backup workflow, which is part of the Server Protection policy.
In NetWorker 8.1.x and 8.2.x, the NetWorker server ran an nsrim process once every 24 hours to remove information about eligible save sets from the client file index and mark eligible save sets as recoverable or recyclable in the media database.
NetWorker 19.1 creates a Policy resource that is called the Server Protection policy. The Server Protection Policy contains the Server Protection group. The Server Protection group is associated with the Server backup workflow, which starts the Expiration action daily at 10 a.m.
Expiration The expiration action expires save sets in the media database based on retention time of the save set. When the retention time of the save set has been reached, NetWorker uses the nsrim process to expire the save set. When a save set expires, the nsrim process performs the following actions:
l Removes information about the save set from the client file index. l If the save set data resides on an AFTD, removes the save set information from
the media database and removes the save set data from the AFTD. l If the save set data resides on a tape device, the nsrim process marks the save
set as recyclable in the media database. When all save sets on a tape volume have expired, the volume is eligible for reuse.
An expiration action is created automatically in the Server maintenance workflow of the Server Protection policy. An expiration action only supports Execute and Skip backup levels.
Changes to bootstrap and index backups NetWorker 19.1 performs a bootstrap and index backup as separate backup action in the Server backup workflow, which is part of the Server Protection policy.
In NetWorker 8.1.x and 8.2.x, NetWorker performs a bootstrap backup when the operations in a group that contains the NetWorker server completes. If the NetWorker server Client resource does not appear in an active Group resource, the bootstrap backup every time a group completes, even when the backup level is set to skip.
NetWorker 19.1 creates a policy resource that is called the Server Protection policy. The Server Protection Policy contains the Server Protection group. The Server Protection group is associated with the Server backup workflow, which starts the Server database backup action daily at 10 a.m.
Server database backup A server database backup action performs a bootstrap backup and can also include the client file indexes.
A bootstrap backup contains the following NetWorker server components:
l Media database l Server resource files. For example, the resource (res) database and the Package
Manager database (nsrcpd) l NetWorker Authentication Service database
NetWorker automatically creates a server backup action in the Server Backup workflow of the Server Protection policy. By default, a full backup of the media database, resource files, and the NetWorker Authentication Service database occurs

NetWorker Server and resource migration 165
daily. A full backup of the client file indexes occur on the first day of the month. An incremental backup of the client file indexes occur on the remaining days of the month. The default retention policy for the server database backup is one month.
The migration process may not assign the bootstrap backup to the pool that was configured in NetWorker 8.1.x and 8.2.x. You can edit the Server database action in the NetWorker Administration window and change the destination pool value or use the nsrpolicy command to update the pool. For example:
nsrpolicy action update server-backup -p "Server Protection" -w "Server backup" -A "Server db backup" --destination_pool pool_name
Changes to the NMC database backup NetWorker 19.1 performs an NMC database backup as separate backup action in the NMC Server backup workflow, which is part of the Server Protection policy. The NMC database backup action creates a staging directory for the database files, performs a backup of the staging directory, and then deletes the contents of the staging directory.
In NetWorker 8.1.x and 8.2.x, the NMC server configuration process created a Client resource for NMC database backups on the NetWorker server. The Client resource contained the following value in the Save set attribute:
NMCASA:/gst_on_server_name/lgto_gst
where server_name is the short name of the NMC server host.
When the update process detects a Client resource for the NMC backup, NetWorker migrates the Client resource, but does not add it to the Protection Group associated with NetWorker 8.1.x and 8.2.x Group resource that contained the NMC Client resource. The migration process makes the following attribute changes to the Client resource for the NMC server database backup:
l Updates the value in the Save set attribute. The Save set field for the client contains the path to the database staging directory. By default, the staging directory is in C:\Program Files\EMC NetWorker\Management \nmcdb_stage on Windows and /opt/lgtonmc/nmcdb_stage on Linux.
Note
The file system that contains the staging directory must have free disk space that is a least equal to the size of the current NMC database. The section "Changing the staging directory for NMC database backups" describes how to change the staging directory location.
The NetWorker Administration Guide describes how to change the staging directory
l Clears the values in the Level and Retention attributes.
When you log in to the NMC server for the first time after an update, the configuration wizard prompts you to define the NetWorker server that will backup the NMC database. When you configure the NMC database backup, the NetWorker server performs the following actions:
l Creates a group called NMC server.
l Adds the Client resource to the NMC server group.
l Creates a workflow that is called NMC server backup in the Server Protection policy. The workflow contains the NMC server backup action, which performs a full backup of the NMC server database every day at 2 P.M.

Procedure
1. In the NetWorker Administration window, click Protection.
2. In the left navigation pane, expand Policies, and then expand Server Protection.
3. In the right window pane, on the Actions tab, edit the NMC server backup action.
The Policy Action Wizard appears, starting with the Specify the Action Information window.
4. Specify a weekly or monthly schedule for the action:
l To specify a schedule for each day of the week, select Weekly by day.
l To specify a schedule for each day of the month, select Monthly by day.
5. Click the icon on each day to specify the backup level to perform. The following table provides details about the supported NMC server backup level that each icon represents.
Table 26 Backup levels
Icon Label Description
Full Perform a full backup on this day. Full backups include all files, regardless of whether the files changed.
Incr Perform an incremental backup on this day. Incremental backups include files that have changed since the last backup of any type (full or incremental).
Skip Do not perform a backup on this day.
Note
The NMC Server database backup only supports the full and skip backup levels. If you edit the NMC Server backup action and change the levels in the backup schedule to a different level, for example synthetic full, NetWorker performs a full backup of the database.
6. Click Next.
The Specify the Backup Options page appears.
7. From the Destination Storage Node box, select the storage node with the devices on which to store the backup data.
Post Update Tasks
NetWorker Server and resource migration 167
8. From the Destination Pool box, select the media pool in which to store the backup data.
9. From the Retention boxes, specify the amount of time to retain the backup data.
After the retention period expires, the save set is removed from the client file index and marked as recyclable in the media database during an expiration server maintenance task.
When you define the retention policy an NDMP client, consider the amount of disk space that is required for the client file index. NDMP clients with several thousands of small files have significantly larger client file indexes on the NetWorker server than a non-NDMP client. A long retention policy for an NDMP client increases disk space requirements on the file system that contains the client file indexes.
10. Click Next.
The Specify the Advanced Options page appears.
11. In the Retries field, specify the number of times that NetWorker should retry a failed probe or backup action, before NetWorker considers the action as failed. When the Retries value is 0, NetWorker does not retry a failed probe or backup action.
Note
The Retries option applies to probe actions, and the backup actions for the Traditional and Snapshot action types. If you specify a value for this option for other actions, NetWorker ignores the values.
12. In the Retry Delay field, specify a delay in seconds to wait before retrying a failed probe or backup action. When the Retry Delay value is 0, NetWorker retries the failed probe or backup action immediately.
Note
The Retry Delay option applies to probe actions, and the backup actions for the Traditional and Snapshot action types. When you specify a value for this option in other actions, NetWorker ignores the values.
13. In the Inactivity Timeout field, specify the maximum number of minutes that a job run by an action can try to respond to the server.
If the job does not respond within the specified time, the server considers the job a failure and NetWorker retries the job immediately to ensures that no time is lost due to failures.
Increase the timeout value if a backup consistently stops due to inactivity. Inactivity might occur for backups of large save sets, backups of save sets with large sparse files, and incremental backups of many small static files.
Note
The Inactivity Timeout option applies to probe actions, and the backup actions for the Traditional and Snapshot action types. If you specify a value for this option in other actions, NetWorker ignores the value.
Post Update Tasks
168 NetWorker 19.1 Updating to NetWorker 19.1 from a Previous NetWorker Release Guide
14. In the Parallelism field, specify the maximum number of concurrent operations for the action. This is applicable if multiple rollover is implemented at an action level.
For Direct-NDMP backups, set the parallelism value to the number of available NDMP drives.
If you set the parallelism attribute to a higher value, there will not be enough drives to support all the queued backup save sets. Large save sets might fail due to the inactivity timeout limit.
When NDMP groups back up simultaneously, divide the number of drives by the number of groups. Use this value for each of the parallelism attributes.
Setting the parallelism value for the group overrides the parallelism value that is defined for the NDMP clients.
15. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but continue with subsequent actions in the workflow, select Abort action.
Note
The Abort action option applies to probe actions, and the backup actions for the Traditional and Snapshot action types.
l To abort the entire workflow if there is a failure with one of the jobs in the action, select Abort workflow.
Note
If any of the actions fail in the workflow, the workflow status does not appear as interrupted or cancelled. NetWorker reports the workflow status as failed.

Troubleshooting authorization errors and NetWorker server access issues
This section provides a list of possible causes and resolutions for error messages that are related to NetWorker Server authorization issues.
Insufficient permissions This message is displayed when the user that you used to log in to the NMC server is a member of many operating system groups and you try to perform NetWorker operations.
When a user belongs to many groups, the total number of characters in the group names can exceed the buffer size that NetWorker allots for the group names. NetWorker excludes characters and group names that exceed the buffer size.
To resolve this issue, edit the Usergroup resource to which the user belongs, and then specify the DN for the user in the External Roles field.
Token has expired This message is displayed when the NMC GUI is open and the token expires for the authenticated user.
To resolve this issue:
1. Click OK. The Enter Credentials window is displayed.
2. In the Enter Credentials window, specify the user password, and then click OK. The NetWorker Authentication Service validates the user credentials and, if the validation succeeds, generates a new session token.
Unable to connect to server: Unable to set user privileges based on user token for SYSTEM: security token has expired This message is displayed when the NetWorker Administration window is open and the token expires for the authenticated user.
To resolve this issue:
1. Click OK. The NetWorker Administration window closes.
2. In the Console GUI, select the NetWorker server, and then select Launch NetWorker Administration. The Enter Credentials window is displayed.
3. In the Enter Credentials window, specify the password of the user, and then click OK. The NetWorker Authentication Service validates the user credentials and if the validation succeeds, generates a new token for the session.
Unable to query resource database: security token has expired This message is displayed when you run a CLI tool as an authenticated user but the user token has expired.
To resolve this issue, run the nsrlogin command to generate a new token for the user.
Unable to connect to server: Unable to authenticate with server "server-name": Authentication error This issue is seen if the NMC (gstd) service and NetWorker server (nsrd) service are installed on separate hosts. When you log in to NMC and click the tabs and options the error: Unable to connect to server: Unable to authenticate with server networker- server: Authentication error: why = Server rejected credentials is displayed. This issue arises due to peering conflict or incorrect permission settings.
To resolve the issue, clear the peering information:

nsrauthtrust -H nmc-server-name -P 9090 nsraddadmin -H nmc-server-name -P 9090
Troubleshooting NetWorker daemon or service startup issues
This section provides a list of possible causes and resolutions for error messages that are related to issues starting NetWorker processes.
Error spawning NetWorker_Installation_directory\rabbitmq- server-3.2.4\erts-5.10.4\bin\epmd -daemon (error 0) This error message appears in the daemon.raw file on a Windows NetWorker server when 8.3 filename support is disabled on the drive that contains the NetWorker binaries or the 8.3 short name for the NetWorker_installation_directory is absent.
By default, the NetWorker_installation_directory structure contains the EMC NetWorker directory, which Windows shortens to EMCNET~1. When 8.3 filename support is disabled on the drive that contains the NetWorker binaries or the 8.3 short name for the NetWorker_installation_directory is absent, Windows cannot find the path to the NetWorker binaries, and NetWorker services fail to start.
Use the dir command in the directory that contains the NetWorker_installation_directory, to determine if the 8.3 short name is absent for the NetWorker_installation_directory.
For example:
l The following dir output shows that the EMC NetWorker directory does not have an 8.3 name:
C:\Program Files>dir /x EMC* Volume in drive C has no label. Volume Serial Number is 5C7F-A00F
Directory of C:\Program Files
Troubleshooting NMC GUI and NetWorker Server connection issues
Troubleshooting NetWorker daemon or service startup issues 175

l The following dir output shows that the EMC NetWorker directory has the 8.3 name EMCNET~1:
C:\Program Files>dir /x EMC* Volume in drive C has no label. Volume Serial Number is 5C7F-A00F
Directory of C:\Program Files
05/02/2016 10:10 AM
To resolve this issue, enable 8.3 filename support, and then set the short name for the NetWorker_installation_directory:
1. Ensure that all NetWorker services are stopped.
2. From a command prompt, change to the root directory of the drive that contains the NetWorker installation files. For example, cd C:\
3. Use the fsutil command to enable 8.3 filename support. For example: fsutil behavior set disable8dot3 0
4. Use the fsutil command to set the short name of the installation directory to the actual name of the installation directory. For example to set the EMC NetWorker directory to the short name EMCNET~1, type: fsutil file setshortname "EMC NetWorker" EMCNET~1
5. Type the command "NetWorker_installation_dir\nsr\rabbitmq- server-3.2.4\bin\rabbitmq-server.bat" status, and then confirm that the output does not display the Error spawning message.
6. Start the NetWorker services.
Note
Check each directory name in the path to the NetWorker_installation_directory. If a directory name is not a valid 8.3 short name, you must set a short name for it.
Issues with GST Database Services In windows platform, if the GST database services are not running, then check for the following.
1. Check whether the nmcdb & nmcdb11 is present under
2. If the directories are present, then rename nmcdb to nmcdb_bkp & nmcdb11 to nmcdb.
3. Open the services window (services.msc), and then manually start the GST Database services.

This error message appears after an upgrade when you attempt to connect to the NMC Server.
The NMC Server daemons are not running and the following error messages appear in the gstd.log file when you start the NMC Server daemons:
gstd NSR error 111 Unable to get authentication service host name and port number. A valid host name and port number are required. gstd NSR error 118 Run the command 'gstauthcfg' in the Console bin directory to set the authentication service host name and port number. gstd NSR warning 39 wakeup error in ACM -- request shutdown gstd NSR warning 23 *** gstd stopping
To resolve this issue, perform the following steps on the NMC Server:
1. From a command prompt change to the directory that contains the NMC Server installation files. The default directory location is C:\Program Files\EMC NetWorker\Management\GST\bin.
2. Type the following command: gstauthcfg.exe -c -h authentication_host - p authentication_port where:
l authentication_host is the host name of the NetWorker Server that provides authentication services to the NMC Server.
l authentication_port is the port number used by the NetWorker Authentication Service on the NetWorker Server. The default port number is 9090.
3. Start the gstd service.
An error occurred while validating user credentials. Verify that NetWorker Authentication Service is running.
This error message appears when the NMC server cannot validate user credentials with the NetWorker Authentication Service.
This message can occur for more than one reason:
l The NetWorker Authentication Service daemon did not start on the NetWorker Server that authenticates the NMC Server because another application has started an Apache Tomcat instance on the same service port. In the situation, the following error message also appears in the Catalina log file: SEVERE: Failed to initialize end point associated with ProtocolHandler ["ajp-bio-8009"] java.net.BindException: Address already in use: JVM_Bind

n Linux: /nsr/authc/tomcat/logs/catalina.out n Windows: C:\Program Files\EMC NetWorker\nsr\authc-server
\tomcat\logs\catalina.date.log To resolve this issue, perform the following steps:
1. Use the netstat command on the NetWorker Server to determine which application is using the same port as the NetWorker Authentication Service:
n On Linux: netstat -anbo | grep port_number n On Windows: netstat -anp | findstr port_number
2. Remove the application that starts the other Apache Tomcat instance or change the listening port that the application uses.
3. Restart the NetWorker processes on the NetWorker Server.
l The firewall configuration prevents the NMC Server from contacting the NetWorker Authentication Service on the NetWorker Server.
To resolve this issue, ensure that the firewall rules allow communication between the NMC server and NetWorker server on the port that you configured for the NetWorker Authentication Service. The default port is 9090.
Tuning the JVM heap memory You must set the JVM heap memory to a maximum of 1 GB if you are using a 32-bit with a 32 bit JRE.
