Overview of DD Management Center 9

About DD Management Center The DD Management Center product is a scalable, virtual appliance-based solution for centralized management of multiple Data Domain systems (DD systems).

DD Management Center provides capacity and replication resource management, health and status monitoring, template-based reporting of aggregated data, customizable grouping and filtering of managed DD systems via activity monitoring dashboards that support multiple user roles.

DD Management Center provides current and historical data for its managed objects, with subject presentation ranging from site-wide summaries to drill-down detail for a selected object.

DD Management Center is installed and runs on a VMware system (as described in the EMC Data Domain Management Center Initial Configuration Guide). It is released separately from the DD OS software and hardware releases.

DD Management Center can monitor all Data Domain platforms, with the exception of Global Deduplication Array (GDA) systems. DD Management Center can monitor systems running DD OS version 5.1 or later.

Note

For a complete list of new features, see the EMC Data Domain Management Center Release Notes.

DD Management Center Capabilities DD Management Center is a Rich Internet Application (RIA) comprised of a set of browser- based pages that allow you to monitor managed objects.

Some of the DD Management Center uses are to:

u Monitor the health and operation of managed objects on a user-defined dashboard u Display site-wide storage capacity, showing aggregated usage totals u Graph current and historical data about space usage, data consumption, and daily

written data trends u Monitor operational status of configured replications and set thresholds that

generate alerts when there are lagging replications u Estimate projected capacity needs based on historical trends, and pinpoint specific

dates (both past and future) for usage comparison u Generate usage and performance reports on demand or set up a schedule and email

list to facilitate proactive management u Manage user access through configurable Role Based Access Control (RBAC) settings

With DD Management Center, you can create custom groupings of DD systems, organized in ways that are meaningful to you. Applying groups and properties to managed objects customize the content displayed on pages for how objects are monitored and can be used to organize how the objects represent your infrastructure.

DD Management Center also allows some feature configuration for its managed systems, such as managing user access and upgrading the OS of a DD system or groups of systems.

From DD Management Center, a user can open a DD System Manager session for a managed system to provide full single-system management capabilities. In this way, DD

Overview of DD Management Center

10 EMC Data Domain Management Center 1.1 User Guide

Management Center provides both advanced multiple system management capabilities, and full single system management capabilities.

DD Management Center can process alerts from all of its managed DD systems, which are viewed from a single list.

How Does DD Management Center Differ from DD System Manager?

The EMC Data Domain System Manager (DD System Manager) is primarily a single system management tool that provides centralized monitoring and management for up to 20 systems. DD System Manager does not aggregate storage and/or performance data from multiple systems, nor can you compare operational information among systems, as provided by DD Management Center.

DD Management Center includes an embedded version of the DD System Manager that can be launched, providing convenient access to a managed DD system for further investigation of an issue or to perform configuration, if necessary. See Launching DD System Manager on page 36 for details.

Logging In and Out of DD Management Center Access to DD Management Center is through a supported browser from a workstation that has network access to the VMware server hosting DD Management Center.

Use one of these browsers for the operating system that is running on your workstation (see the EMC Data Domain Management Center Release Notes for most-recent supported browser and Adobe Flash versions):

u On Windows XP Pro: Internet Explorer 8, Firefox 7 and later, Google Chrome

u Windows 7: Internet Explorer 9, Firefox 7 and later, Google Chrome

u On Mac OS X: Firefox 7 and later, Google Chrome

To allow file downloads to show a prompt dialog in Internet Explorer, we recommend that the Security Zone in which the DD Management Center's hostname or IP address belongs has the Automatic prompting for file downloads option set to Enabled for that Security Zone.

To change this setting for a specific Security Zone:

1. Select Tools > Internet Options to see the Internet Options dialog.

2. Click the Security tab, then select the Security Zone that applies to the DD system.

3. Click Custom level... to open the Security Settings dialog, then scroll down to the Downloads section.

l For the Automatic prompting for downloads option, select the Enabled radio button, then click OK. If a prompt appears asking if you are sure you want to change the settings for the Security Zone, click Yes.

4. Click OK to exit the Internet Options dialog.

Note

If DD Management Center is not already installed on the VMware server, refer to the EMC Data Domain Management Center Initial Configuration Guide for instructions.

DD Management Center supports multiple simultaneous users.

Logging In to DD Management Center Procedure

1. Open a browser and enter the hostname or IP address of DD Management Center.

A Secure Login link is provided for establishing a secure connection over the network using HTTPS instead of HTTP. This option uses a self-signed certificate by default, which the user must accept, despite browser warnings.

2. In the login window, enter a user ID and password and press Enter or click Login.

Note

The initial login requires using the sysadmin user ID and the "changeme" password (which is the default password). You will then be prompted to change the sysadmin password. On subsequent logins, other users (that have been added to DD Management Center) with different roles can be used (see Manage Local User Access to DD Management Center on page 64).

Once you log into DD Management Center, the Dashboard displays showing the default set of monitoring widgets.

Logging Out of DD Management Center When you want to log out of DD Management Center, click the Logout button (right- pointing arrow on the right side of the banner) or use the standard Close button on the browser window (see Global Controls and Icons on page 82 for complete descriptions of GUI controls, including picture of the Logout button).

Note

Use the mouse to hover over any button or other graphical element to learn names of controls or see more details.

Continuing DD Management Center Configuration Once the installation procedure is complete, as described in the EMC Data Domain Management Center Initial Configuration Guide, the DD Management Center is running a basic configuration, but needs additional settings configured to be fully functional. The sysadmin may need to add licenses for additional DD systems, configure network settings and routing tables, set timezone configuration, and provide access for users. Procedures to perform all these and more is described in Performing Advanced Configuration on page 41.

Continue with the following sections to learn about how to use the features of the DD Management Center.

About the DD Management Center Page Elements The DD Management Center page is composed of the banner, navigation panel, work area, and the status bar.

Figure 1 DD Management Center Page Elements

Getting Started

Logging Out of DD Management Center 15

Unless the dashboard is maximized, the banner is visible at all times and provides controls to filter the scope of the work area's active page (the filter control only appears on monitoring pages), open the online Help, and log out.

The navigation panel is organized by modulesDashboard, Health, Capacity, Replication, Reports, Administration, and Inventory. Within each module, click on the name of a subject page to display it in the work area. Descriptions of all pages are provided in About the DD Management Center Interface on page 81.

The status bar shows the active user name and role, evaluation license expiration date countdown (including a pop-up with a link to register), date, and alerts notifications (click to see an informational pop-up with a link to the Alerts page).

Standard global controls (add, edit, delete) allow interaction with the application and manage how information shows on pages with tables (sorting column content by ascending/descending controls, hiding/displaying columns), and are described in the section Global Controls and Icons on page 82.

Navigating the DD Management Center Page There is a sequence for navigating a DD Management Center page to change the focus and scope for the content displayed in the work area. The procedure illustrates this, as seen the related graphic, where the numbers correspond to the following steps:

Procedure

1. Select a module topic in the navigation panel.

The default view for the page opens in the work area.

2. If included, click a tab on the top right to change the content on the page (for example, in the screenshot, display capacity by DD systems, not MTrees).

3. If included, click a toggle button at the top right of the page to change the page view between a standard tabular list and a grouped tabular list.

For a page displaying groups, only the groups created by the user are shown.

Planning How Managed Objects are Organized When you add DD systems to DD Management Center, the wizard includes options to assign them to one or more groups and to set characteristic properties.

Getting Started

16 EMC Data Domain Management Center 1.1 User Guide

Therefore, before you start to add your DD systems into DD Management Center, it is helpful to plan how you want to organize and catagorize your managed objects (DD systems, MTrees, and replication contexts).

u Groups can only be applied to DD systems. For details on creating groups, see Creating Groups on page 17.

u Properties can be applied to DD systems, MTrees, and replication contexts. A set of system properties are automatically assigned when systems are added (DD system model, DD OS version, domain name), so only your custom properties need be assigned. For details on creating properties, see Creating Properties on page 18.

Once you create the groups and properties, they can be assigned as you add your DD systems, although doing so at this time it is not required.

Creating Groups Groups are logical containers for a collection of Data Domain systems under a name identifier, organized in a hierarchical structure that the DD Management Center admin user creates. Groups facilitate the management and monitoring of Data Domain systems and are helpful for performing searches. When used by filters, groups reduce the scope of objects that are returned. Groups can contain other groups and/or DD systems, once they have been added. A group can belong to only one group, but a DD system can belong to many groups.

Start by creating one or more super-groups at the Groups level, and then add sub-groups and DD systems.

Note

DD systems cannot be added at the root Groups node.

Procedure

1. From the Administration > Groups page, click Add.

2. Enter the name for the group, then click Save.

Note

Group hierarchy structures cannot be changed. They must be deleted and then re- created to change the structure.

3. To add additional groups at the root level, click Add. In the Add Group window, ensure only the / is in the Path text box. Enter a name for the new group and click Save.

The /newgroup is listed in the Groups panel.

4. To add a sub-group to a group, select the group from the Groups panel, click Add, enter a name for the group, then click Save.

The sub-group is nested under the parent group in the Groups panel.

5. Once DD systems have been added into DD Management Center, they can be added into a group. Select the target group from the Groups panel and click Add. In the Add Group window, select a DD system from the Available Systems panel, click > to move the system into the Systems in the group panel, then click Save.

The DD system displays in the Group "groupname" details" panel when the group is selected in the Groups panel. When a DD system resides in more than one group, hover the cursor on the Information icon to display the group assignments.

Getting Started

Creating Groups 17

After you finish

To manage groups, see Managing Groups on page 24.

Creating Properties Properties are a mechanism to annotate or tag something about a DD system (such as the type of data stored, the department or owner, or its location) to facilitate searching, filtering, and organizing.

Properties are useful to filter the contents of a tabular listing of objects (such as the list of DD systems in the Inventory > Systems page) and narrow the scope of output produced by a dashboard widget or generated report, for example.

Once the property is created, you can set a value for property. The value can be a string of words, a boolean expression, or a fixed value string.

A set of default administration properties are applied to a system when it is added into DD Management Center (the DD system's model type, OS version, and domain name). You can create and assign other properties as needed. For additional information on properties, see Properties on page 95.

To create properties:

Procedure

1. From the Administration > Properties page, select the tab for the type of object that you will assign the property to (System, MTree, or Replication) and click Add.

2. In the Add Property dialog, enter a name for the property and select its operation type:

l StringAllows a string of up to 256 characters to be set when assigning the property. The string is the property name, and you give it a value when you assign the property. For example, the string may be Location, and you can set a value to America, China, Japan, etc.

l BooleanCreates a condition where you can assign one of two values (for example, a value of True or False, or Yes or No).

l Fixed Value StringAllows you to set one or more strings (names) when assigning the property. Selecting the option Add Multiple Assignments allows you to assign more than one value to a property.

3. Click Add.

After you finish

After properties are created, you can assign them to an object (see Assigning Properties on page 22).

Adding Data Domain Systems Before you begin

To manage a Data Domain system, it needs to be added to the DD Management Center inventory with the procedure described in this section. A maximum of 75 Data Domain systems can be added to a DD Management Center, provided that licensing for that number of systems is in place. See Managing DD Management Center Licenses on page 42 if licensing is required.

Getting Started

18 EMC Data Domain Management Center 1.1 User Guide

Note

A Data Domain system can only be managed by a single DD Management Center. Once a system is in a DD Management Center's inventory, if an attempt is made on another DD Management Center to add the system, the attempt will only be honored by selecting the Override adding systems check box. When the Override checkbox is selected, the system is added to the new DD Management Center, and the systems status is changed to the unmanaged state on the original DD Management Center, where data collection is suspended for that system.

Use this procedure to add (register) DD systems to the DD Management Center. Groups of up to 20 systems can be registered at one time:

Procedure

1. From the Inventory > Systems page, click Add. Enter the following for the first DD system, then click Add to continue adding systems (up to 20 systems). Make sure there is a check in the box next to the system being added. Click Register to continue:

l Fully-qualified host name (use alphanumeric characters, dashes, periods, and underscores) or IP address (required)

l The sysadmin password used on the Data Domain system (required)

l Inbound and outbound IP address (or hostname) and port settings used by the firewall (optional). If this option is selected, and the port setting is not changed by the user, the default (3009) is used. If modified by the user, a port number must be between 1 and 65535. The default port settings allow the DD Management Center to communicate with the Data Domain system. If the ports have been changed on the firewall or the Data Domain system, they should be updated here as well.

l Check certificate information by clicking in the associated cells (optional). The Subject name in the DD Management Center CA certificate should match the DD Management Center hostname or SSL will fail the host verification.

2. A status page reports the success and failure of the additions. In the event of an error, click Back to return to the beginning of the wizard to display error messages and correct errors or delete the system. Once there are no errors, click Next to continue to the Properties page or Close to quit.

Note

On the Status page, the Next button is disabled until all errors are corrected.

3. Optionally, on the Properties page, select check boxes from the available properties list to assign properties to the DD systems and click Next to continue to the Groups page.

4. Optionally, on the Groups page, select check boxes from the available groups list to make all DD systems members of the selected groups and click Next to continue to the Thresholds page.

5. Optionally, on the Thresholds page, set warning and critical capacity thresholds for the DD systems (shown on capacity views and in reports).

6. Click Finish.

Results

A progress bar appears on the page showing the progress of the initial data synchronization for the newly added DD system(s). Additionally, the job progress details can be tracked on the Health > Jobs page.

Getting Started

Adding Data Domain Systems 19

Note

See About Communication Between the DD Management Center and DD Systems on page 97 if there are problems resolving the DD system hostname when trying to add the system.

Once a DD system is added to DD Management Center, all historical information for the DD system is copied to DD Management Center. Thereafter, DD Management Center retrieves operational data every 10-15 minutes and saves it to its database. DD Management Center monitoring tools draw on this data for current and historical reporting and for trend projections.

See the status icon section of Global Controls and Icons on page 82 for information about the various states a managed DD system can be in, and the probable causes for going into that state.

Changing DD System Configurations Once DD systems have been added into the DD Management Center, use the following procedure to change their configured settings:

Procedure

1. On the Inventory > Systems page, select one or more systems and click Edit to open the Edit Systems window.

Note

When more than one system is selected, if different values are configured for the same setting among selected systems, the field will show Mixed values. If the value is change, all systems receive the new value. A More Details control shows the saved value for the setting.

2. In the Edit System window, change any of the following settings on the appropriate tab (click Apply or change tabs to save the new settings and continue reconfiguration):

l ConfigurationAdd or change the inbound and outbound Firewall IP address (or hostname) and port settings. The firewall port is optional. If not entered by the user, the default (3009) is used. If entered by the user, it must be between 1 and 65535.

l PropertiesAssign a value to a property. A list of properties (default and user- created properties) are listed in this tab. You can assign properties to this system as needed. Default system properties (Model, OS, and Domain Name) are not editable.

l GroupsAdd or remove group assignments. Select or deselect group assignments for the system. Any number of groups and subgroups can be selected.

l ThresholdsChange configuration settings for warning and critical capacity thresholds for the system (shown on capacity views and in reports). Upon editing multiple systems with mixed warning thresholds, initially the warning value shown is zero.

Upon editing multiple systems with mixed critical thresholds, initially the critical value shown is 100.

3. Click OK to save and exit system reconfiguration.

Working with the Dashboard The Dashboard holds widgets that you create from a set of monitoring functions. Widgets can be organized on separate pages using tabs. Widgets can include specific systems or groups of systems that can be filtered by group, property, system, or custom rule.

Use the Dashboard to quickly check important conditions such as unreachable systems, active alerts, diminishing capacity, and so forth. See Check Dashboard Status Widgets on page 28 for more information about how to perform monitoring.

By default, each user is assigned a Dashboard with one tab, populated by one each of the supplied widgets, configured to cover all systems that a user is monitoring. You can modify, add to, or even delete this default Dashboard tab.

Organize the Dashboard with Tabs Widgets can be organized on separate tabs. A tab with all its widgets can be copied to a new tab and then edited. A maximum of 7 tabs are supported.

Some example uses for tabs can be to organize a set of systems based on group membership, location, OS version, data type, and so forth.

Another suggestion for organizations could be by widget type, for instance, a tab containing Current Health Status widgets for all systems.

Add Tabs Procedure

1. On the Dashboard > Monitoring page, click the Configure Tabs control (see Dashboard on page 84 for dashboard control details) and click Add.

2. In the highlighted text field, enter the name for the tab, choose the number of columns on the tab (more columns produce smaller widgets), and order the placement of the tab across the dashboard using the Move Up or Move Down controls.

3. Click Save.

Working with Filters Filters are used to selectively define the output of a DD Management Center function. For example, filters can be used to define the scope of elements that display on a page, tailor the output of a Report, and target which DD systems are monitored for Dashboard Widgets. The Filter global control appears on pages and dialog boxes whenever a filter can be used.

The drop-down menu on the Filter control allows you to select which groups, properties, DD systems, and rules can be used for filtering. When a filter is active on a page, the Filter control is highlighted in yellow. Filtering can be switched on or off using the Filter control as a toggle. See Global Controls and Icons on page 82 for more details.

The Filter by rule option allows you to create custom rules that can be saved for reuse or run in the current location. The rule can be built using any of the standard filter criteria (groups, properties, DD systems) along with any existing properties or groups that have been created. Controls for logic (is, is not, contains, does not contain, etc.) are provided and statements can be inclusive or selective. To create a custom rule:

Procedure

1. From the Filter menu control, select Filter by rule.

2. In the Name field, provide a name for the filter.

3. Using the selection menus in the Match the following rule area, create the criteria for your rule. The criteria consists of one or more statements.

Create the first statement by selecting an object from the first menu (for example, DD system, group, model, or existing property) and a logic condition (for example, contains, does not contain, is, is not), then the target (text you input or a menu selection, based on the previous selections). For example, a statement could be Model is DD880.

4. If necessary, either add more statements with the Add row control or add conditions to the rule using the Block control ("Match all or Any of the following rules") and create additional statements.

5. Click Save to make this filter available from the Filter menu list or click Filter to run the filter once and exit.

6. To remove the filter and return to unfiltered content, select Clear filter from the Filter menu.

Note that the filter may still be available with the Recent filters option on the Filter control list.

DD Management Center Licenses DD Management Center is introduced with a 90 day trial license for managing 5 DD systems, after which it must be updated with a purchased license key to operate.

Monitoring Systems with DD Management Center 27

Overview of Monitoring Systems The monitoring tools included in DD Management Center facilitate examining a wide array of operational information about managed Data Domain systems. Once a Data Domain system is added to DD Management Center, all historical information for the system is copied to DD Management Center, and every 10-15 minutes DD Management Center retrieves operational data and saves it to its database. DD Management Center monitoring tools draw on this data for current and historical reporting and for creating trend projections.

DD Management Center monitoring tools are highly visualusing charts, graphs, and color coding to help the user interpret essential data points and facilitate alerting for critical markers.

DD Management Center monitoring tools help you focus on areas of interest. They can show mile-high status checks of all managed DD systems, check a specific group of DD systems, as well as drill down to check the health or operational history of a single systems components. For capacity monitoring, you can easily check current operation, historical data, and perform capacity predictions that are based on usage trends.

Using the filtering and grouping options provided on monitoring pages, DD Management Center easily allows you to shape the data presentation so you can focus on viewing just the information you need.

In addition to data provided on the paged interface, you can generate reports to compile operational data that can be exported. Reports can be generated ad hoc or scheduled and emailed to a list interested parties.

Perform Daily Monitoring Using DD Management Center to perform daily monitoring of your site can help proactively check for any unusual activity before it can progress to become a serious problem.

The sections that follow describe tasks you should perform at least daily to get an overview of the operational status of your DD systems and data replications.

Check Dashboard Status Widgets The Dashboard > Monitoring widgets provide an overview of key performance indicators for your monitored DD systems. Widget functions allow you to check the health and status of DD systems, be alerted to storage capacity threshold warnings and replication lags or failures.

The graphs, dials, and color-coded alerting on the widgets make it easy to spot system operational anomalies. Many components on the widgets provide a link to the full- featured page for the function so you can drill-down to see complete information.

By default, one tab is provided named All Systems that is populated with one of each type of widget, configured to monitor all managed DD systems.

A Status button appears at the top right corner of a widget (except for the Alerts widget) if any of its monitored systems are not online. Clicking the Status button opens a panel showing the count of systems with connection issues. Clicking the Show Health Status link opens the Health > Status page, where a list of these systems displays.

Monitoring Systems with DD Management Center

u Clicking on the alert bar navigates to the Alerts page, filtered by the widgets configured filters and the type of alert category.

Check System Capacity Check the System Capacity widgets to spot shortfalls in overall managed storage capacity and to monitor managed systems storage usage.

Capacity Overview Check the Capacity Overview widgets to see if any systems are nearing warning or critical storage capacity levels.

Also, if configured, monitor the projected capacity usage for the upcoming selected interval.

Space Usage Check the Space Usage widgets to monitor aggregate totals of storage levels for the DD systems it is configured to manage. This widget monitors the total storage capacity of all systems (for space that is used and available) or a selected group if a filter is set. Check pre-compressed space usage and compression ratios to verify that deduplication is working as expected.

Check Replication Progress Check the Replication widgets for replication status, problems, and statistics.

Replication Status This widget highlights replications with performance problems for the widgets monitored systems. Also, if configured, shows total bytes written and total bytes replicated in the last 24 hours.

Top Replication Lags The Top Replication Lags widget shows source DD systems with replication pairs exhibiting critical and warning lag, ranked by severity (Critical, followed by Warning) and by longest delay. The lag time for the worst performing replication pair on the system is

Managing Data Domain Systems 35

Launching DD System Manager From some DD Management Center pages, there is a control to launch a DD System Manager session for the selected Data Domain system to perform configuration or troubleshooting. The launched version of DD System Manager actually runs on DD Management Center and not on the Data Domain system, thereby providing the user with centralized and secure administration for multiple Data Domain systems simultaneously.

To initiate a session, select an entry in a table listing (for example) and click the Launch DD System Manager control from any of the following DD Management Center pages:

u Health > Alerts

u Capacity > Utilization

u Capacity > Projected

u Replication Pair Details Lightbox

u System Details Lightbox

Note

Be sure the pop-up blocker on your browser is configured to allow pop-ups for DD Management Center.

The DD System Manager session that starts (in a new window) requires no login or logout and provides complete management of the Data Domain system. DD System Manager opens showing the corresponding area from where it was launched (for example, if the launch was from the Alerts view, the Alerts page on the Data Domain system is opened).

The launched DD System Manager appears the same as a native DD System Manager session except the navigation panel, Reports and Task Logs tabs are omitted. The banner shows the DD Management Center name, and for the DD system, name, OS release, model type and role of invoker.

For the launched DD System Manager:

u A user can only launch DD System Manager on a system for which he/she has an admin role.

u A permission is comprised of a managed object (system or group), a user (local or NIS) and a role.

l Admin role is required for replication configuration and IPMI configuration.

l The Security Officer role is not supported

u The inventory of Data Domain systems on DD Management Center are used.

l The Data Domain systems that are shown are based on the effective permissions of the user.

l Only the replication source and destination systems that are registered with the DD Management Center are shown.

u No additional firewall ports need to be opened for the session (that is, once a Data Domain system is added to DD Management Center, the existing port assignments are used for the DD System Manager connection).

Upgrading Data Domain System Software The DD OS on one or a group of Data Domain systems can be upgraded from DD Management Center. A user must have admin rights on the DD System to upgrade and manage upgrade packages.

The DD OS upgrade is comprised of these phases:

u Obtain a DD OS upgrade package, either:

l Download an upgrade package from the Data Domain Support Web Site

l Upload to the DD Management Center a previously obtained DD OS upgrade package that had been saved locally (via the browser)

u Perform the DD OS upgrade on the Data Domain systems.

Managing DD System Upgrade Packages You can create a collection of upgrade packages to use when upgrading the DD OS on managed Data Domain systems.

First you will download the upgrade package from the Data Domain Support Web Site to a locally-accessible drive and then add the package to the DD Management Center upgrade package collection.

Procedure

1. Navigate to the Inventory > Systems page.

2. Select the menu option Upgrade > Manage Upgrade Packages.

The inventory of upgrade packages that are installed on DD Management Center and ready for use are listed.

3. Select the appropriate option from the Manage Upgrade Packages window:

l Click the Data Domain Support Web Site link to obtain an upgrade package to store locally.

l To upload a package that has been stored locally to the DD Management Center inventory, click Add and browse to the local drive to select the package.

Results

Once the upgrade package has been uploaded to DD Management Center, it can be used to upgrade one or more DD systems.

Performing DD System Upgrades The DD OS on one or more Data Domain systems can be upgraded from DD Management Center with one upgrade operation.

Procedure

1. Navigate to the Inventory > Systems page.

2. In the Inventory table, select one or more target systems for the DD OS upgrade.

Ensure the OS column is visible.

3. From the Upgrade menu, select Upgrade.

4. In the Upgrade Systems window, select the DD OS version from the drop-down list.

Managing Data Domain Systems

Upgrading Data Domain System Software 37

Versions that display in the drop-down list reside on the DD Management Center; they have been either downloaded from the EMC Data Domain Support Web Site or uploaded from a local drive, as described in the previous topic.

The body of the window shows any warnings for replication dependencies. Errors such as version incompatibility (generally a maximum upgrade jump of two DD OS versions is allowed, with the exceptions allowing upgrades from DD OS 5.1 to 5.4 and DD OS 5.2 to 5.5) prevent the upgrade from completing.

5. Click Upgrade to upgrade the selected systems.

If systems are not in an acceptable managed state (unreachable, suspended, upgrading, for example) the upgrade action is unavailable.

Note

Depending on the number of DD systems selected for the upgrade and other factors, the upgrade may take a while. After the upgrade, each DD system automatically reboots. File access is interrupted during the upgrade. Progress for the upgrade can be tracked on the Health > Jobs page.

Creating Access for Users To allow a group of users to access DD Management Center:

Procedure

1. Go to Administration > Settings page and select the Access > Local Users tabs.

2. Click Create to add users and access groups (NIS and Active Directory) to DD Management Center.

User can now log into DD Management Center, but cant see any other system. Add permissions to view (user role), administer (admin role), or take snapshots (backup operator) for groups and DD systems.

Users and user groups have either admin or user roles. If a user or a user group has the admin role, they can view all DD systems by default; it is not necessary to set any other permissions for admin users and groups. For users and user groups with the user role, perform the next step to set permissions on DD systems so that these users may view the systems.

3. To add permissions, go to Administration > Permissions page and click Add.

For background information about Permissions, see Permissions on page 94.

4. Select where to add the permission:

l Add permissions to SystemsSelect this option, and from the list of managed Data Domain systems, click check boxes of the systems where the permissions are to be assigned.

l Add permissions to GroupsSelect this option, and from the list of groups, click check boxes of the groups where the permissions are to be assigned.

5. In the User area, click + (Add), select one or more users from the Select Users dialog box, and click Select.

6. Click in the Role field for the user, and select the access role: Administrator, Backup Operator, or User.

7. Click Add.

The users are given the assigned role (Administrator, Backup Operator, or User) for the selected systems or groups.

Tips

To simplify permissions manageability:

u Minimal use of the admin role for the DD Management Center is recommended:

l Have very few admin users of DD Management Center since this role can manage all DD systems in the DD Management Center inventory. In addition, the admin user for the DD Management Center configures the DD Management Center properties and groups, and assigns its permissions.

l Configure most logins for DD Management Center to have the user role on DD Management Center.

u Use NIS user groups for permissionsthis simplifies the process for adding, removing, and modifying users without changing the permission assignment.

u Use DD System Groups for permissions rather than assigning permissions to individual systems. By assigning permissions at the group level, policy-based permissions can be used with a union model that is applied to the entire group hierarchy.

To simplify permissions manageability:

u Start with lower level permissions at the top of the hierarchy:

l Assign lower level permissions towards the root of the Group hierarchy.

l Assign higher level permissions towards the leaf of the Group hierarchy.

l Use a union model, not an override model. This makes it easy to change permissions at lower levels without affecting the entire hierarchy.

Verify Changes:

u After assigning permissions or changing group membership, verify the change by looking at the Effective role for a system.

Use Central Administration:

u Use DD Management Center to centrally administer all systems, reducing the use of local accounts on each managed DD system. Turn off direct GUI access to DD systems that are managed by DD Management Center.

Managing DD Management Center Licenses DD Management Center is a downloadable product with an initial 90-day fully-functional evaluation license and evaluation serial number to manage 5 DD systems.

At any time during the trial period, you can convert from an evaluation to a permanent license and serial number. With a permanent license, you are able to add licenses to manage additional DD systems.

If the license is not converted before the trial period expires, data collection is paused. After applying a purchased license and serial number, data collection resumes, data is synchronized, and older data is available for view on historical views.

Note

During the evaluation period, alerts are sent as reminders when the remaining time reaches 60 days, 30 days, 7 days, and daily until expiration.

Configuring Routes Routes determine the path taken to transfer data to and from the localhost (DD Management Center) to another network or host.

DD Management Center does not generate or respond to any of the network routing management protocols (RIP, EGRP/EIGRP, and BGP) in any way. The only routing

Performing Advanced Configuration

50 EMC Data Domain Management Center 1.1 User Guide

implemented on DD Management Center is based upon the internal route table, where the administrator may define a specific network or subnet that a physical interface (or interface group) uses.

DD Management Center uses source-based routing, which means that outbound network packets that match the subnet of multiple interfaces will only be routed over the physical interface from which they originated.

Note

The routing for connections initiated from DD Management Center (such as for replication) depend on the source address used for interfaces using the same subnet. To force traffic for a specific interface to a specific destination (even if that interface is on the same subnet as other interfaces), a static routing entry between two systems can be configured and will override source routing.

View Route Information Procedure

1. Select Administration > Network > Routes.

Working with SNMP To monitor DD Management Center using SNMP, you will need to install the Data Domain MIB in your SNMP Management system. The Data Domain MIB can be obtained by following the instructions in Download the SNMP MIB on page 56. The Data Domain MIB will allow SNMP queries for Data Domain-specific information.

DD Management Center also supports the standard MIB-II so you can also query MIB-II statistics for general data such as network statistics. For full coverage of available data you should utilize both the Data Domain MIB and the standard MIB-II MIB.

DD Management Center supports SNMP V2C and/or SNMP V3. SNMP V3 provides a greater degree of security than V2C by replacing cleartext community strings as a means of authentication with user-based authentication using either MD5 or SHA1. As well, with SNMP V3, user authentication packets can be encrypted and their integrity verified with either DES or AES.

The default port that is open when SNMP is enabled is port 161. Traps are sent out through port 162.

Tips for Managing Access to DD Management Center Since mutual trust is established between the DD Management Center system and the registered Data Domain systems, DD Management Center users also have access to the Data Domain system.

If a user is added with admin level access, that user can also access the Data Domain systems (through ssh or by launching the DD System Manager GUI) to perform admin level operations. Furthermore, an admin level user can invoke an upgrade operation on a registered Data Domain system.

While this is not really a security issue, it should be noted that caution should be taken when adding users to a DD Management Center system treat it the same as you would for adding users to a Data Domain system.

The type of access role assigned to individual users or groups of users determine which DD Management Center functions they can use to access data about the managed system and its status.

About Access to DD Management Center Functions Many DD Management Center pages provide information about the Data Domain systems it manages. Other DD Management Center pages provide the ability to configure and manage aspects of the DD Management Center system itself. And some pages provide access to the managed Data Domain system.

Alerts 87

Jobs The Health > Jobs page displays information about jobs (also called tasks) that have been initiated from the DD Management Center, including jobs still in progress and jobs that have completed, whether successfully or not. Details of a task, including its subtask status are shown for a selected task in the Details panel.

When upgrading one or more DD systems, the progress of a selected In-progress task can be paused and resumed with the Status control.

Tasks can run on the DD Management Center alone or can run on the DD Management Center and a Data Domain system. For example, the Report Generation task runs solely on DD Management Center; other tasks, like Upgrade, run mostly on the Data Domain system, but a skeleton process on DD Management Center keeps track of its progress. And still other tasks run mostly on the DD Management Center (like Adding Systems), but have subtasks that run on the Data Domain systems.

Note

Tasks that run on DD System Manager (native to the Data Domain system) are not shown in the Jobs listonly those tasks initiated from DD Management Center are shown.

Additional job-status filtering controls for the table are located at the top left of the page, enabling the inclusion of jobs that have succeeded, failed, or are still in progress. If no selection is active, no jobs are shown.

The list of tasks that display is dependent on the role of the person: u A person with a User role on a system or DD Management Center only see the tasks

they initiated on that system or DD Management Center u An Admin on a DD system or DD Management Center sees all jobs on that DD system

or DD Management Center. For detailed information about roles and their management, see Tips for Managing Access to DD Management Center on page 73.

Capacity The Capacity module provides storage usage information for the Data Domain systems and MTrees being managed by DD Management Center. This includes an overview of both current and historical space consumption, as well as an estimate of projected future (12 month) storage needs.

Utilization The Capacity > Utilization page shows storage usage amounts, organized as a list of DD systems or MTrees. This page has controls for opening the System Details lightbox for examining in-depth information about a system, charting storage data history, launching a DD System Manager session, and exporting data to a CSV spreadsheet program for viewing or saving.

The System page can be filtered by viewing the tabular listing by system or group name. Clicking an entry in the systems table displays detailed connection status information in a notification banner below the table.

In the Capacity > Utilization page, when the System filter is selected, space usage amounts are shown for the current time and last 24 hours, Pre-comp used, and configurable columns showing Compression Factor, Cleanable, and Capacity Thresholds for Warning and/or Critical states (by default, thresholds are set to 80% for warning and

90% for critical; they can also be set from the Inventory > Systems page Edit control). The Warning and Critical Capacity Thresholds columns can be sorted by ascending/ descending controls and it can also filtered by an entered value (greater, lesser, or equal to entered value).

Selecting the MTrees view on the Capacity > Utilization page, displays the type of MTree (which can be sorted by ascending/descending and filtered by MTree or SU), space usage amounts for Current Pre-Comp Usage, Quota, Quota Available, Quota Used % are shown. The Space Usage area in the Details Panel shows Pre-Comp, Post-Comp, Comp Factor: Last 24 hours, Last Week, Last 5 week Avg. Properties viewing and setting is supported as well as charting historical storage data. Note that Post-Comp data for an Mtree can only be determined over a time interval (last 24 hours, last 7 days, etc.), not for a point in time.

Note

The Space Usage amounts may not exactly match capacity totals reported by the DD System Manager. Because of the polling delay of up to an hour, DD Management Center reporting will always lag. This is especially true if there is a lot of churn on the monitored system; the discrepancy will be more visible and there is a possibility that DD Management Center may never catch up with the DD System Manager capacity totals.

Aggregated totals of selected objects (Individual or aggregated systems or MTrees) in the master table (top) are shown below in the Space Usage details panel and graphed in the Charts and Trends panel. Detailed charting is shown for Space Usage, Consumed (Systems only), and Daily Written. Charting controls allow selectable time intervals by manipulating the slider to magnify an interval or clicking a fixed time range (1 day, 7 days, etc).

Note

This guide assumes you are familiar with the capacity terms, as introduced in the EMC Data Domain Operating System Administration Guide. Refer to that guide or the DD System Manager online help for explanations of the terms.

System Details Lightbox Use the System Details lightbox when you want to gather detailed operating information about specific components of a DD system.

The System Details lightbox is accessed from the Inventory > Systems, Replication > Overview, and the Capacity > Utilization and Capacity > Projected pages using the System details control. Open the System Details lightbox when in-depth information about the selected DD system is needed.

The Details page shows the operational status of various system components (such as the file system and protocols) using LED status indicators. Also provided are summaries of file system usage and capacity, and replication status and statistics for inbound and outbound replications. Charts for tracking space usage, consumption, and daily written data allow you to see historical usage trends.

The Charts page allows you to create charts to plot operational data about the system resources (CPU utilization or network throughput), file system and protocols activity, and replication data (viewable by automatic or on-demand type) for throughput, inbound, and outbound replications.

u The Stream Count chart shows the number of reopened read file streams in the past 30 seconds (r+), the number of active read streams (rd), the number of reopened write file streams in the past 30 seconds (w+), and the number of active write streams (wr).

About the DD Management Center Interface

Utilization 89

u The Protocol Processing chart shows the number of operations per second.

u The Protocol Throughput chart shows the protocol throughput (amount of data that the file system can read from and write to the kernel socket buffer) and the wait time (time taken to send and receive 1 MB of data from the file system to the kernel socket buffer).

Charting controls allow selectable time intervals by manipulating the slider or clicking a fixed interval (hours, 1 day, 7 days, etc).

Projected The Capacity > Projected page can help you plan future capacity needs:

u Predict when systems will run out of storage space

u Determine future capacity needs by projecting historical and current trends

u Estimate when a system will reach its system-specific warning/critical space usage thresholds

The Capacity > Projected page provides tabular information for monitored systems. Each entry shows the system name, model, OS version, and a connection status icon with pop- up containing a link to the Health > Alerts page). The space usage amounts (size, used, and free) for current, selected past and projected months are provided. A storage graphic depicts the system's capacity by percentage used, with color coding to show normal, warning and critical threshold levels.

Click on the timeline to select a specific month (past or future). This creates a date column for that date for comparison analysis. Projections are based on the historical data and require at least 15 daily data points to work. Informational messages are displayed if insufficient data prevents an accurate projection.

Insufficient data causes include the following:

Forecast Engine Output DD Management Center Message - - Insufficient capacity used The average space used in the last 7 days was less than

Replications The Replication pages provide status and performance details about the replication pairs on the managed Data Domain systems.

u The Replication > Overview > All Pairs page lists each monitored Data Domain system that has configured replication pairs. Expand a system entry in the table to see its inbound and outbound replications, and for these, expand to see the replication type: Automatic (DD system to DD system replications) and On-demand (client- initiated and controlled replication of DD Boost files), and expand those to see the pairs of that type. The Inbound and Outbound entries are shown only if there are configured replications for that direction type. Use the column selector to display columns for replication status, number of pairs (totals for systems, inbound, and outbound replications) and a selectable/ configurable time-interval for displaying historical replication data. Double-click a status error icon at the system level to open the System Details lightbox, where hovering over the Replication LED exposes a pop-up with a link to the Alerts page, filtered for the pairs in error. The Status error icon for a category (inbound, outbound, system) shows if any of its items has an error condition.

Note

Use the right triangle System control at the top left of the table to expand the inbound and outbound tiers to see all Automatic and On-Demand replications (if the system entries have not been expanded yet), and likewise to collapse all expanded entries.

When the Topology page is active, the site replication pairs are shown on a topology map (see Topology on page 92).

u The Replication > Automatic page lists all monitored DD system replications for the types directory, collection, and MTree. The page banner displays the total count of monitored Automatic replications, and the table shows for each replication pair selectable columns for the status, source and destination systems, and performance data such as lag time (The lag cell shows red when the lag duration is greater than or equal to the Critical threshold and yellow for Warnings. Hover the cursor over the cell for detailed information about the lag threshold.), lag trend (increasingthe data cannot be replicated within the lag threshold), steady, decreasing, or no arrow if the pair is suspended or in error), time over threshold (hover the cursor to see policy settings), bytes remaining, and status message text. The page-specific controls includes Assign Properties (see Assigning Properties on page 22) and Lag Threshold Policy/Manage Lag Threshold Policies (to set/manage alerting for when an Automatic Replication lag time exceeds the set time limit for critical and warning levels; see Managing Replication Pair Lag Threshold Policies on page 25).

u The Replication > On-Demand page lists (DD Boost) file replications, showing for the pair: the last transfer status, source and destination storage units, and performance data for recent and completed replications. The table can organized by Pairs or Groups using the view option at the page top right.

u Historical data for completed replications can be by viewed for the past 24 hours, 7 days, 30 days, 90 days, or by setting a custom time frame. Details shown are for Pre- comp data replicated, completed and failed replicated files, percentage of failure, and the last error messages. For the group view, data for pairs are rolled up at each group level. Data for all pairs are summarized at the last line of the table.

About the DD Management Center Interface

Replications 91

Note

The number of completed and failed files can include file replications that the system retried up to four times due to generally-recoverable failures. Consequently, the sum of the completed and failed file replications can be greater than the total number of file replications that were initiated by the DD Boost applications on the replication pair.

Note

On-demand replication monitoring requires DD OS 5.3.1 or DD OS 5.4 software on the DD system. Replications between DD system running older software will not display On-demand replication associations between the source and destination systems on any of the On-demand replication reporting pages, widgets, or reports. If at least one endpoint of the replication is running DD OS 5.3.1 or later, DD Management Center can show the pair of systems but displays the storage unit name as Unresolved.

Note

If the source or destination fields show an IP address instead of a hostname, the DNS server configuration for the DD system should be modified. When configuring DD systems to monitor On-demand replication, ensure their DNS servers include configuration for both forward and reverse hostname lookup. Without proper DNS server configuration, DD systems will not be able to translate from IP addresses to host names and the source and destination paths will contain IP addresses rather than host names.

u The replication Pair Details control is active when a pair is selected, and shows a wealth of replication details (see Replication Pair Details Lightbox on page 93).

u The System Details control is active when a DD system entry is selected on the Overview page.

u The Export CSV file control sends the overview listing with performance data for last 7 days to a file with comma separated entries (for viewing in Excel, for example).

Pairs The Replication > Automatic Pairs view (default view) is a tabular listing of all replication pairs, sorted by either the source system or group name. The tabular columns are user selectable and can show the replication source and destination systems, lag time, lag trend (increasing, decreasing, or steady), threshold policy, bytes remaining, last sync time, and status message.

Cascades The Replication > Automatic Cascades view is a tabular listing of replication cascades. Expand and collapse a cascade to show or hide their pairs. The tabular columns are user selectable and can show the replication cascades status, source and destination, lag trend, threshold policy, bytes remaining, last sync time, status message, type (MTree, collection, or Directory), and estimated completion time.

indicators and other map controls to allow the user to easily locate and drill-down to investigate error conditions.

Use the Type menu to select the replication types that are shown in the map work area (MTree, directory, collection, and On-demand files). If a replication type has not been configured among the site's replications, its check box in the menu is disabled. If a type is enabled but de-selected, those node relationships do not show on the map.

A slider on the map controls the scope of replication contexts that are shown in the work area display.

The inset is a miniature representation of the map and its scope is controlled by the slider manipulation. The inset itself can be selected and moved around to include or exclude systems in the map work area.

Replications status between systems are shown with color-coded directional lines, which will show red if any of the replications are in error. Mousing over the line shows the number of replication pairs and a count for each status levels.

Use the plus and search controls on a system's icon to expand to show an in-depth view of all the replication pairs that are configured. The minus control collapses this view.

The right panel lists the replicated pairs (of highlighted systems in the map work area or all contexts is nothing is highlighted), showing the type of context, source and destination systems, status, with a link to additional details. Selecting a context activates the Pair Details control.

Replication Pair Details Lightbox Selecting a replication pair on any of the Replication pages activates the Pair Details control. Clicking Pair Details opens the Replication Pair Details lightbox, which shows a wealth of information about the replication pairlast transfer status, source and destination systems, settings such as encryption, operational status, and color-coded icons showing capacity levels. Below this area are charts for viewing historical activity for Pair Characteristics (plot performance factors such as pre-compression written, pre- compression replicated, replication compression factor, network bytes) and for all pairs except On-demand replications the Lag Trend (plot replication lag, replication lag thresholds, pre-compression written, and pre-compression remaining). Mouse over the Thresholds check box to display the lag threshold settings.

Note

If a Storage Unit for a DD Boost replication pair shows the message "SU is unresolved," one of the following may be the cause:

u The remote system is not registered with DD Management Center.

u Both systems are registered, but one is running a DD OS earlier than 5.3.1, and is not able to report the SU name.

u The remote host name is an IP address and cannot be matched to a registered host name.

Click the Charts tab to plot the elements of the selected replication (Pair Charts, System Charts and other Replications). Track pair characteristics, CPU utilization, data written, and network and replication throughput over time. Also available are options to track All Pairs Characteristics and Common Pairs Characteristics (which can show either Automatic replications only, On-demand Replications only, or All replication types). The All Pairs charts can show Incoming or Outgoing replication data for a system. The Common Pair Characteristics show a subset of data series that are common across both types of

charts. The charts are vertically aligned for source and destination systems by the same time interval, allowing comparisons for both systems at any point in time.

Note

The Pair Details and System Details options are also available by right-clicking a pair entry in the table.

Reports The Reports feature allows you to compile specific information about managed systems, based on three default template types (capacity, replication, and status). A wizard helps configure a template for the reports content, schedule, and email distribution. A report can be generated from a template ad hoc (the template is not saved) or saved (as a template) for generating reports for later use.

Note

If a user who is the owner of report templates is deleted from DD Management Center, the ownership of those templates is changed to the DD Management system administrator.

Note

DD Boost monitoring requires that DD OS 5.3.1 or DD OS 5.4 software is running on the DD system you are monitoring. Any DD system running older software will not display DD Boost replication pair associations between the source and destination systems on any of the file replication reporting pages, widgets, or reports.

See Creating a Report on page 33 usage information.

Management Configuring reports to notify recipients with information about managed objects reduces the need for users to log into DD Management Center to obtain status.

Use the Create Report Template wizard, which is started with the Add control, to create the template that is used to generate reports. See Creating a Report on page 33 for details.

Once the report template is created, it is listed in the table where it can be viewed, edited, deleted, renamed, downloaded and saved. The template can also generate a report at will.

Selecting a report in the table shows an historical listing of its generated output in the Details panel. These reports can be viewed, searched, edited and deleted.

Administration The Administration area is where settings for DD Management Center are managed. The Administration module includes sections for permissions, groups, properties and settings.

Permissions The Permissions views show what permissions are assigned to users of DD Management Center by assigned role.

About the DD Management Center Interface

94 EMC Data Domain Management Center 1.1 User Guide

Permissions are a triangle that involve three components:

u The managed object (groups or systems)

u The user (local, NIS, or Active Directory)

u The DD System Manager role (Administrator, Backup Operator, or User)

The Permissions pages are also used to add, modify, and remove permissions from groups and systems. See Creating Access for Users on page 38 for details.

Each of the views show the users, their assigned role and their effective role.

Groups The Administration > Groups page is where the DD Management Center system administrator creates groups in a tree-like hierarchy for logically organizing DD systems. Each tier of the hierarchy can contain one or more systems or subgroups. The Group page left panel shows the created group hierarchy; selecting a group in this panel shows its contents (which can be subgroups or systems) in the right panel. Groups are shown as a folder icon. An informational icon displays for systems that reside in more than one group, and these groups are listed.

There is only one root (/), but it can contain multiple groups (in the Add Group dialog box, set the Path to /, add the group name in the text field; the group created is directly under root). Groups can contain nested groups and DD systems.

The structure of the hierarchy or the contents of the groups are changed with the Group edit controls (Add, Edit, Remove, and Cut/Copy/Paste).

Group creation and modification can only be performed by the DD Management Center system administrator. Any user can apply group designations and see the complete group structure, although RBAC permissions control which systems are displayed for a user.

The Groups page includes the following icons:

Controls Name Description - - -

Group A group containing DD systems or other groups. When subgroups are present, the expander icon displays to the left of the folder. Clicking the folder displays the members of the group in the Group Details panel.

A group with permissions applied

This group is controlled by access permissions.

Membership details

Appears when a DD system belongs to more than one group. Click this icon to view the names of groups the DD systems is a member of.

Properties Properties are tags you create to classify systems and the data contained in MTrees and Replication Contexts for searching, filtering, and organizing. Properties can help filter the contents of a tabular listing of objects (such as the Inventory > Systems page) and change the scope of a dashboard widget or generated report. The value of a property can be a string, number, a boolean, or a fixed value string.

Properties are organized and managed by type (DD system, MTree, and Replication), and selecting a property type displays a catalog of its active properties.

Controls for adding DD systems, editing an existing DD system's settings, viewing a selected DD systems' details, upgrading DD systems, and launching the System Manager are included on this page.

About Communication Between the DD Management Center and DD Systems When adding a DD system to the DD Management Center, the IP address or hostname of the DD system you provide in the Add System wizard is used along with valid DNS entries to set up communication between the DD Management Center and the DD system. Once contact is established with the DD system, its hostname is used thereafter unless proxy settings were provided in the wizard.

If communication cannot be established because the DNS entry does not exist or is incorrect for either the DD Management Center or the DD system:

u Add or correct the DNS entry for the DD Management Center or the DD system, or

u If a proxy is not used between the DD Management Center and the DD system, use the proxy settings as a workaround for a missing or incorrect DNS mapping by providing the DD system IP address as the outgoing proxy address and/or the DD Management Center IP address as the incoming proxy address.

To troubleshoot communication with the DD system:

u Use the command net ping hostname from both the DD Management Center and the DD system. This command will report the problems that need to be fixed, but may not work if the firewall is causing the blocking.

u Use the command managed-system sync. All DD systems are synced with this command (but it will consume additional network bandwidth). Without this command, a sync is run automatically every hour.

Command-Line Interface 99

Overview of the CLI DD Management Center has a command-line interface (CLI) that was derived from the Data Domain Operating System (DD OS) and modified to support some management tasks and the virtual machine environment. This chapter describes the DD Management Center CLI.

Note

The main user interface for DD Management Center is the Web-based graphical user interface (GUI). In general, EMC Data Domain recommends that you use the GUI for system management tasks; however, a few system administration tasks for the DD Management Center system itself require that you use the CLI.

The DD Management Center CLI differs from the DD OS CLI in the following ways:

u Additional system management commands (managed-system and task) specific to DD Management Center that perform the basic registration, administration, and job management functions for the DD Management Center. The following sections describe these commands:

l DD Management Center managed-system Commands on page 100

l DD Management Center task Commands on page 104

u Some CLI system administration commands derived from the DD OS are modified to support DD Management Center. The command output for many of these commands omits information that is not applicable to the systems role as a management virtual appliance rather than a storage appliance.

u Some CLI commands derived from DD OS have limited arguments because a DD Management Center does not directly manage storage.

u Some DD OS commands that perform tasks for managing storage (and are therefore not useful or supported in DD Management Center) were removed.

For detailed information on any CLI command, start a secure shell session (ssh) and type ? at the CLI prompt to see the online help.

DD Management Center managed-system Commands The DD Management Center managed-system CLI commands let you add and remove systems from management, change their proxy host settings, and suspend, resume, or synchronize data collection.

Note

You can also use the Web interface to perform these actions.

managed-system add managed-system add [force] [inbound-proxy [inbound-proxy-port ]] [outbound-proxy [outbound-proxy-port ]] This command adds a Data Domain system into the set of systems that are managed by the current DD Management Center. The command prompts you to:
