Revision Date Description

02 March, 2016 Updated for DD9500.

01 December, 2014 Added information to the Utilities Menu section - erase NVRAM data and save support bundle to a USB key.

Overview and supported systems Data Domain provides both online and offline diagnostics for its systems:

l Online diagnostics are invoked on the Data Domain operating system (DD OS) command line. Some of these, such as system status and enclosure show all, which report the status of fans, power supplies, and temperature sensors, also run automatically in the background to monitor the system during runtime. Alerts are issued and emails are optionally sent when problems are detected.

l Offline diagnostics are run in response to customer problem reports, such as when a system cannot be booted to online operation, a card or disk is absent, or memory, connectivity, or configuration problems are suspected. Offline diagnostics check FRUs such as the system controller disks, motherboard, memory (DIMMs), NVRAM card(s), and other hardware.

Major differences in the use of online and offline diagnostics are:

l Offline diagnostics are used when the system is unable to come online.

l Offline diagnostics are used if the system is hanging frequently or has serious performance issues. These diagnostics can isolate performance problems to specific components.

l After online diagnostics detect a problem, offline diagnostics may be needed for further fault isolation or confirmation.

l Online diagnostics detect problems only when they access the part of the component that has the problem, whereas offline diagnostics test the full range of the component an entire disk, for exampleand can detect latent faults.

Data protection

Note

Diagnostics are run in offline mode and require a reboot to load.

In offline mode, the Data Domain file system is not running, and no customer data is flowing through the system. Tests are completely data-safe and non-destructive.

Supported systems The next table shows which diagnostic tests can be run on each supported Data Domain system (DDxxx[x]) and which FRU is tested. For test coverage information, see Diagnostic test descriptions on page 30.

Requirements

System controller boot disk or USB key with DD OS To boot offline diagnostics, you must have one of the following:

l A functional system controller boot disk with DD OS 5.5 (or a later version) installed.

l A dedicated USB 2.0-compatible key (a.k.a. keychain drive, thumb drive, or flash memory stick), 2 GB or larger, with DD OS 5.5 (or a later version) installed and inserted into one of the systems USB ports. USB keys must be formatted as FAT32 (Unix VFAT). Refer to the EMC Data Domain Operating System USB Installation Guide, available on the EMC Online Support site, to request and download a bootable DD OS USB image and install it onto a USB key.

Note

Starting with DD OS 5.5, you can run offline diagnostics from a USB key on systems running the same DD OS version or any of the previous four versions (DD OS 5.45.1). You can also run offline diagnostics on systems running later versions of DD OS, however diagnostic logs will be written only to the USB key and not to the system disk.

USB key (optional for saving logs) After running diagnostics, log files are automatically saved to the system boot disk and to an external USB key, if one is inserted. You can also insert a USB key and save logs to a USB key from the Main Menu after they are written to the system disk.

You may want to use a USB key to store log files if:

l Diagnostic logs cannot be written to the system disk. (You are prompted to insert a USB key, or cancel without saving logs.)

User's Guide

4 EMC DD OS 5.7.1 User's Guide

Note

If you are running offline diagnostics from a USB key on a system with a later version of DD OS, diagnostic logs will not be written to the system disk, but will be written to the USB key.

l You might not be able to reboot the system to online mode to access the offline diagnostics log file (a concatenation of all logs) on the system boot disk.

Requirements for the USB key are:

l FAT32 (Unix VFAT) format

l 10 MB of free space

For more information on viewing log files on the system or USB key after running offline diagnostics, Getting log information after running diagnostics on page 29.

Note

If you booted offline diagnostics from a USB key, you can use the same key to store log files if it has at least 10 MB of free space.

System downtime The typical time required to run all tests in the suite is 75 to 90 minutes, depending on the system type and configuration.

The next table shows the maximum possible run time, to the nearest minute, for each test in the offline diagnostics user interface. Maximum run time is the test execution time plus the time needed for the diagnostic to time out if it cannot complete. This is always greater than the test execution time.

12 EMC DD OS 5.7.1 User's Guide

Rebooting the system and running diagnostics Offline diagnostics are part of the DD OS software and can be run from:

l The system boot disk

l A USB key with a bootable DD OS image Refer to the EMC Data Domain Operating System USB Installation Guide, available on the EMC Online Support site, to download a bootable DD OS USB image and install it onto a USB key.

Note

In this section, you power up or reboot the Data Domain system. If the system is crashed or hung and cannot be powered up or rebooted, contact EMC Customer Service.

Launching offline diagnostics from the system boot disk Procedure

1. Connect a console to the system, if not present, using one of these methods:

l Remote serial link: Use for a serial console or laptop with terminal emulation software such as Secure CRT, PuTTY, or HyperTerminal (required for running DD OS commands). A null modem cable with a DB-9 female connector is required. Laptops without a serial DB-9 connector should use a USB/Serial adapter (not included) with the null modem cable. Connect the console or laptop to the standard DB-9 male or micro DB-9 female port on the system.

l Direct connection: Use for a PS/2 or USB keyboard with a VGA monitor, or KVM console. Connect the P/S2 keyboard and mouse to the system's DIN-type ports, the USB keyboard to the system's USB-A port, and the VGA monitor to the system's DB-15 female port.

Note

KVM is not supported for DD2200, DD2500, DD4200, DD4500, and DD7200 systems.

l Remote IPMI/SOL link: Use any of the console types listed above. Connect to the system's RJ45 receptacle, as follows: For DD880 systems, use either of the built-in Ethernet ports; for other systems, use the Maintenance port.

Note

DD140, DD610, and DD630 systems do not support IPMI or SOL.

2. If the system is powered down, power it up as follows:

l If the system has a power button on the front, press it.

l If the system does not have a power button on the front, remove (if inserted) the AC power cords from the power supplies, wait until the power supply LEDs have turned off, then reconnect the power cords.

Skip to step 4.

3. If the system is powered up and there is a system prompt on the console, stop any backups that are running or wait until those backups are completed, then:

This feature collects a large subset of the DD OS state and log files which are normally collected when a support bundle can be gathered from a running DD OS system. The system saves the support bundle on the USB key in the following subdirectory: /mnt/diag-usbkey-mnt/diag_sub/sub-MM-DD-hh-mm/. The time of the support bundle is recorded in the directory name: MM is the month, DD is the day, hh is the hour, and mm is the minute. The support bundle is packaged in a tar file, compressed by gzip, and named: support-bundle.tar.gz. This feature is helpful:

When collecting data from appliances that cannot boot the Data Domain Operating System (DD OS), but can boot to Offline Diagnostics.

If LAN connectivity cannot be established.

l Settings - Specify your systems model from a list of supported models if it is not identified correctly at top of the Main Menu (see Bringing up the offline diagnostics main menu on page 33).

Click OK to continue to the Diagnostic Recommendations screen (Performing the recommended service actions on page 26).

Performing the recommended service actions If one or more diagnostics fail, the Diagnostic Recommendations screen displays service actions suggested by the failing diagnostics. Perform all recommended service actions before concluding that the FRU has failed.

CAUTION

Recommended service actions can include reseating and replacing cards and other components. These activities involve powering down the system and removing system covers for FRU access. Follow the FRUs installation guide to perform these tasks. These guides are available on the EMC Online Support site.

Using Log Files Most diagnostics contain several subtests that check different conditions and, upon failure, generate a different recommended service action for each. Recommended service actions appear on the console, but the conditions that generate them are recorded only in the full test log. Before performing the recommended service actions, you can display the full log file to get more information on the failing condition (see Viewing log files on page 27). You can also view log files after exiting diagnostics (see Getting log information after running diagnostics on page 29).

Viewing log files There are several ways to access log files:

l From the Diagnostics Recommendations screen, type L.

l After diagnostics have been run, you can return to the Main Menu at any time and select Examine Diagnostic Logs to see logs for all passed and failed diagnostics.

l To view logs after exiting diagnostics, see Getting log information after running diagnostics on page 29.

Logs for failed diagnostics include recommended service actions. Returning to the Main Menu also causes logs to be written to a USB key, if one is inserted. If you want to copy current logs to a USB key later, select Save Diagnostic Logs to USB Key in the Main Menu.

Note

All logs on a USB key are erased when a subsequent diagnostics run finishes and new logs are written. To preserve existing logs, copy them to another device before running diagnostics again.

Diagnostic Log Access Menu From the Diagnostic Log Access Menu, you can select and display logs for all tests run. If diagnostics are run more than once, all logs from the previous run are removed before the new logs are written.

Note

The navigation and selection keys available for a screen can be obtained by displaying the help window (press F1). These are also listed in Keyboard shortcuts for diagnostic screens on page 36.

Saving logs and exiting diagnostics

Saving Test Log Files to the System Controller Disk and a USB Key Exiting from the following windows results in log files being written to the system boot disk and to an external USB key (if one is inserted):

l Diagnostics Run screen with All tests PASSED (select OK, then press Enter)

l Diagnostic Recommendations screen (press the Esc key or the Q key)

l Diagnostic Log Access Menu (select Return to Main Menu, then press Enter)

Status screens appear while the required drivers are loaded and logs are written, then control is returned to the Main Menu.

Note

l You can run offline diagnostics on systems running later versions of DD OS, however diagnostic logs will be written only to the USB key and not to the system disk.

l If a core dump occurs while you are running offline diagnostics, the core file is written to the SUB area for analysis by EMC Customer Service. Core files are not saved to USB keys.

Saving Logs to a USB Key Only Logs cannot be saved to the system controller boot disk if:

l The current DD OS release, or one of the four previous releases is not installed.

l Disk hardware is not functional.

l The disk has been swapped out (serial number mismatch with system).

User's Guide

28 EMC DD OS 5.7.1 User's Guide

l A system controller upgrade was started, but did not complete.

If logs cannot be saved to disk and no USB key is present, you are prompted to insert a USB key. You can use any FAT32 (Unix VFAT) formatted USB key with at least 10 MB of free space. If you do not insert a USB key, no diagnostic logs are saved.

Note the following messages:

l No USB key present or not formatted correctly indicates that the inserted key is defective or not formatted properly. Verify formatting and try a different port or a different USB key.

l Could not write log files to USB key indicates that the key has less than 10 MB of free space.

After logs are successfully saved to the USB key, you are returned to the Main Menu.

Remove the USB key before exiting the Main Menu (and rebooting the system).

Continue to the next section, Getting log information after running diagnostics on page 29.

Getting log information after running diagnostics After running diagnostics, ASCII-format logs are:

l Concatenated and written to a single diag_log.sub file on the system disk.

l Written as separate files to a USB key (if one is inserted).

Viewing the log file on the system disk If you are able to reboot the system to online mode, you can get the logs from the last offline diagnostics run. These are concatenated into single file on the system boot disk: /ddr/var/log/debug/platform/diag_log.sub You can view this file using the DD OS log view command as follows:

# log view debug/platform/diag_log.sub

A diag_log.sub file is provided in Example system disk log file on page 41.

Viewing the log files on a USB key Log files are written to a USB key, if inserted, when you return to the Main Menu after running diagnostics or when you select Save Diagnostic Logs to USB Key on the Main Menu. These logs are displayed when running offline diagnostics.

The parent log directory /diag_logs is created off the USB root and a subdirectory / log-mm-dd-hh-mm is created (where mm = month, dd = day, hh = hour, and mm = minute the logs were saved). Individual diagnostic logs and a log of the diagnostic flow are saved in this subdirectory. These logs are saved in ASCII format for viewing on any Linux or Windows machine.

Note

All logs on a USB key are erased when a subsequent diagnostics run finishes and new logs are written. To preserve existing logs, copy them to another device before running diagnostics again. However, a support bundle gathered by the Support Bundle utility is not erased after the bundle is saved on the USB key.

A USB log file is provided in Example USB key log file on page 42.

System Inventory Displays information on system hardware. (See list on page 20.)

BBU Diagnostic Detects faults in the Battery Backup Unit (BBU) on system DD2200 that uses this module instead of NVRAM boards.

CPU MCE Test Decodes and prints the stored machine check record generated by a machine check event.

l Most errors can be corrected by the CPU using internal error correction mechanisms. Uncorrected errors cause machine check exceptions that may panic the system.

l The MCE error condition displayed by the test unambiguously identifies the faulty component.

CPU SSE Test Compares Adler and SHA1 checksums generated by SSE and non-SSE instructions for the same random data.

CPU Test Tests the processors ability to perform a Compress UncompressCompare operation sequence.

l An MD5 fingerprint is generated for the data file before it is compressed. The compressed file is then uncompressed and its MD5 fingerprint is compared against the one generated for the original file.

HDD Comprehensive Test Tests all system controller disks.

l Reads disk sectors and their SMART data.

HDD Quick Test Tests the system controller boot disk only.

l Reads disk sectors and their SMART data.

Memory Diagnostics Tests available free memory and reports any ECC errors (correctable and uncorrectable) detected by hardware.

l Identifies and reports a failing DIMM or DIMM pair.

l Reports a failing memory riser on DD880 and DD990 systems.

Motherboard PCIe Topology Test Checks that HBA cards (SAS, NIC, VTL, and NVRAM) conform to legal system model configurations and are in appropriate slots.

l PCIe interconnect tests exercise and verify the PCIe subsystem. They ensure the connectivity for all the PCIe-based controllers and other IO targets present on the motherboard.

l The tests scan the entire PCIe fabric, starting from the PCIe root and looking for expected PCIe topology. The tests indicate errors if an expected device or a set of devices is absent.

Network External Loopback Test Tests if the network controllers data path is functional through the NIC Tx and Rx ports. Built-in Ethernet and dual- and quad-port NICS can be tested; single-port NICs cannot be tested. This test generates and sends out packets, and expects to receive the same number of packets.

Note

l Before you run the Network External Loopback Test, loopback cables must be installed. For instructions, see Installing loopback cables on page 35. Installing loopback cables for the Network External Loopback Test does not affect running the Network Internal Loopback Test.

l If you previously enabled the old-style network port names option in DD OS, see Mapping to legacy network port names on page 38 for the corresponding new, slot-based port names used by Offline Diagnostics Suite.

Network Internal Loopback Test Tests if the network controllers data path is functional to the MAC layer. Loopback is through the internal loopback interface (MAC layer); packets do not leave the controller. This test generates and sends out packets and expects to receive the same number of packets.

Note

If you enabled the old-style network port names option in DD OS, see Mapping to legacy network port names on page 38 for the corresponding new, slot-based port names used by the Offline Diagnostics Suite.

NVRAM Card Test Performs the following tests and checks:

l Tests all partitions of NV memory on one or multiple NVRAM cards. Scans through the entire range to NV memory in each partition.

l Checks Memory ECC.

l Checks battery status.

l Checks battery state (enabled/disabled).

SAS Diagnostics Test Tests the SAS topology to determine the reliability of the connections:

l Pinpoints SAS connectivity problems to specific links.

EMC Data Domain Operating System Offline Diagnostics Suite Users Guide

Diagnostic test descriptions 31

Table 10 Offline Diagnostic Test Coverage (continued)

Test Name Coverage

l Tests each external SAS Host Bus Adapter (HBA) port and attached shelf chain.

l Generates read traffic to find errors that occur only under load.

Failures are reported by slot.

SAS HU Diagnostics Test Tests the SAS controller in the system controller.

l In the log and runtime display, lists all system controller disks present and which disks are used to exercise each SAS link.

l Generates read traffic to test the SAS links in the system controller and provides recommended service actions if there are connection problems.

SATA HU Diagnostics Test Tests the SATA controller in the system controller.

l Checks if the number of disks reported by the SATA hardware matches the expected configuration and generates a recommended service action if there is a mismatch or the SATA controller has failed.

SEL Log Scan Unlike other diagnostics that exercise specific hardware components, this diagnostic fetches runtime system event logs and filters them for possible system hardware and firmware errors, and other noteworthy events. This feature enables you to monitor the system and identify faults while in offline diagnostics mode. Errors must be resolved manually; no FRU-specific service recommendations are provided.

VTL Diagnostic Checks the following conditions:

l The FC link is up or down.

l A LUN has been assigned to the FC port.

l Link reception errors have occurred.

Failures are reported by slot and port number.

Note

The logic does NOT exercise the FC interface by reading or writing any data. This is because the VTL is a passive device and does not originate transactions. The diagnostic only gathers and interprets hardware state information.

Installing loopback cables Loopback cables must be installed when you run the Network External Loopback Test. You can use the cables currently installed on the system, or equivalents. Cross-over cables are not necessary. Using the wrong cable will cause the test to fail.

Note

Before removing or changing any cable connections, note or mark the connector and port locations, so that you can easily restore them after running diagnostics.

Loopbacks can be implemented between built-in Ethernet ports, or between ports on the same Ethernet card (NIC) as shown in the figure. Refer to the Hardware Overview or Installation and Setup Guide for your system to obtain the location of built-in Ethernet ports and optional NIC slot assignments.

Note

Do not make a loopback from the maintenance port or single-port cards, which are not supported for loopback testing.

Connect the loopback cables as follows:

l Built-in Ethernet (RJ45), Intel SFP+, or Chelsio: Connect the two ports.

l Other NIC copper ports (RJ45): Connect ports on the same card. (Rx and Tx are determined automatically.)

l Other NIC fiber ports: Each port has Tx and Rx connectors. Connect the Tx side of one port to the Rx side of the other port (on the same card).

Mapping to legacy network port names By default, DD OS 4.9 replaces the port names used in older releases with slot-based port names. While you can optionally use the legacy names in the current DD OS release, the Offline Diagnostics Suite uses only the slot-based names.

If you have legacy port names enabled (the default for many systems that have been upgraded from a previous version of DD OS), these names are used in system alerts, output from the net show hardware command, and in the Net show hardware section of ASUP reports, for example. You must consult the tables below to get the equivalent slot-based names.

Slot-based port names use the following syntax: eth slot_number port_letter In this syntax,

l slot_number is a system slot.

l port_letter is one of the ports of the named slot.

Example port names include eth0a, eth0b, eth2a, eth2b, and so on.
