Overview of DD Management Center 11

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

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

Comprised of a set of browser-based pages, DD Management Center, a rich Internet application (or RIA), is installed and runs on a VMware system, as described in the EMC Data Domain Management Center Initial Configuration Guide.

DD Management Center can also configure and monitor secure multitenant DD Boost backup and replication storage on multiple DD systems.

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

DD Management Center Capabilities Using the robust features of DD Management Center, you can:

l Monitor the health and operation of managed objects on a user-defined dashboard

l Display site-wide storage capacity, showing aggregated usage totals

l Graph current and historical data about space usage, data consumption, and daily written data trends

l Manage the DD Secure Multitenancy (SMT) feature, especially to configure and monitor DD Boost access

l Monitor operational status of configured replications and set thresholds that generate alerts when replications lag

l Estimate projected capacity needs based on historical trends, and pinpoint specific dates (both past and future) for usage comparison

l Generate usage and performance reports, on demand, or set up a schedule and email list to facilitate proactive management

l Manage user access through configurable RBAC (role-based access control) settings

With DD Management Center, you can create custom groupings of DD systems, organized efficiently and intentionally. Applying groups and properties to managed objects lets you customize how content will be displayed, to best represent your infrastructure.

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

From DD Management Center, you can also open a DD System Manager session for each managed system to provide full single-system management capabilities. In this way, DD Management Center provides both advanced multiple-system management capabilities and full single-system management capabilities.

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

Overview of DD Management Center

12 EMC Data Domain Management Center 1.2 User Guide

Differences between DD Management Center and DD System Manager

The primary differences between DD Management Center and DD System Manager are the number of DD systems that each can manage, how these systems are managed (in an aggregated or non-aggregated manner), and whether storage is directly managed.

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. DD System Manager does directly manage storage (using VTL, CIFS, NFS, DD Boost, etc.).

DD Management Center provides centralized management for up to 100 DD systems, and you can perform the same task on all of these systems at the same time. Storage and performance data is aggregated for all systems, as well. Operational information can also be compared across systems.

You can launch DD System Manager from DD Management Center to get more information about, or to perform configuration for, a managed DD system.

Backing up and Restoring in a VMware Environment Any process that creates and restores a snapshot of your entire virtual machine can successfully protect your DD Management Center installation.

It is highly recommended that you perform a snapshot before doing an upgrading procedure.

DD Management Center does not depend on having any integration with the backup software.

After the snapshot is restored, DD Management Center automatically performs any necessary application recovery.

Suitable backup software choices would include VMware Data Recovery (VDR), EMC Avamar, etc.

As with any data protection software, make sure to test your setup after you have installed your chosen backup software.

Note

The use of cloning has not been validated.

Getting Started 15

Logging In and Out of DD Management Center DD Management Center is accessed by using a supported browser on a workstation that has network access to the VMware server hosting DD Management Center. DD Management Center supports multiple simultaneous users.

The following browsers are supported for use with DD Management Center:

l On Microsoft Windows Microsoft Internet Explorer 9, Mozilla Firefox 30 or later, Google Chrome

l On Apple OS X Mozilla Firefox 30 or later, Google Chrome

Other browser versions may also work. These are the versions that had been validated at the time of DD MC v1.2 product release. See the EMC Data Domain Management Center Release Notes for the most-recent supported browser and Adobe Flash versions.

To enable file downloads to show a prompt dialog in Internet Explorer, it is recommended 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 .

2. In the Internet Options dialog, select the Security tab, select the Security Zone that applies to the DD system, and select Custom level.

3. In the Security Settings dialog, scroll to the Downloads section.

l For the Automatic prompting for file downloads option, select Enable, and select OK. If a prompt appears asking if you are sure you want to change the settings for the Security Zone, select Yes.

4. Select 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.

Logging In to DD Management Center Initial login requires using the sysadmin user ID and the changeme password (the default password). You are then prompted to change the sysadmin password. After that, other users with different roles (that have been added to DD Management Center) may login.

To log into 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 select Login.

Results

After you log into DD Management Center, the Dashboard is displayed, showing the default set of monitoring widgets.

Logging Out of DD Management Center To log out of DD Management Center, select the Logout button (right-pointing arrow on the right side of the banner), or use the standard Close button on the browser window.

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

Continuing DD Management Center Configuration After 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 configure network settings and routing tables, set time zone configuration, and provide access for users.

DD Management Center Page Elements The DD Management Center page is composed of:

1. Navigation Panel

2. Banner

3. Widget (this is the Current Health Status widget)

4. Logout Control

5. Online Help Control

6. Module (this is the Replication module)

7. Work Area

8. Status Bar and Notification Area

Figure 1 DD Management Center Page Elements

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 appears only on monitoring pages), open the online help, and log out.

Getting Started

Logging Out of DD Management Center 17

The navigation panel is organized by module Dashboard, Health, Capacity, Replication, Reports, Administration, and Inventory. Within each module, you can select the name of a subject page to be displayed in the work area.

The status bar shows the active user name and role, date, and alerts notifications (which you can select 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 is displayed on pages with tables (sorting column content by ascending/descending controls, hiding/displaying columns).

Navigating the DD Management Center Page To navigate a DD Management Center page in order to change the focus and scope for the content displayed in the work area, you can use this procedure. In the illustration, 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, select a tab on the top right to change the content on the page (for example, in the screenshot, display capacity by Systems, not MTrees).

3. If included, select 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. Figure 2 Navigating the DD Management Center Page

Organizing the Dashboard The Dashboard holds widgets that you create from a set of monitoring functions. The Dashboard lets you quickly check important conditions, such as unreachable systems, active alerts, diminishing capacity, etc.

You can set up separate tabs on the dashboard and include specific widgets for each of those tabs. Suggested uses for tabs are to organize a set of systems based on group membership, location, OS version, data type, etc. Another suggestion is to organize by widget type, for instance, a tab containing Current Health Status widgets for all systems.

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

Getting Started

3. In the text field, enter the new name for the tab (typing over Copy of ...). .

4. If you want to change the number of columns, select the current number, and change it using the drop-down list.

5. If you want to change the placement of the new tab, use the Move Up or Move Down arrows.

6. Select Save.

Results

The new tab is displayed on the dashboard. You can open the widgets on the new tab to modify their properties.

Modifying Widgets You might want to modify widgets that were copied from a tab as a starting point for a new set. For example, you could change the filter properties to monitor a different group, set of systems, or rule.

To modify a widget, use the Edit widget icon on the title bar to change the name, settings (if available), and filtering.

Note

The widget type (as determined by the widget template) cannot be changed with the Edit function.

Organizing Managed DD Systems When you add a DD system to DD Management Center, the Add systems wizard includes options to assign it to a group, or groups, and to set properties for it.

As you organize and catagorize each system, be aware that:

l Groups can be applied only to DD systems.

l Properties can be applied to DD systems, MTrees, and replication contexts.

l A set of system properties (DD system model, DD OS version, domain name, and data center) is automatically assigned when a system is added, so you will need to set only custom properties.

After you create groups and properties, they can be assigned when you add a DD system, although you can also assign them at any time.

Creating Groups Groups are ways to organize Data Domain systems (DD systems) under a specific name, in a hierarchical structure created by the DD Management Center administrator. Groups are helpful for performing searches. When used by filters, groups reduce the number of systems returned. Groups can contain other groups and/or DD systems, after they have been added. A group can belong to only one group, but a DD system can belong to many groups. You start by creating one or more super-groups at the Groups level, and then add sub- groups and DD systems.

Getting Started

20 EMC Data Domain Management Center 1.2 User Guide

Note

DD systems cannot be added at the root Groups node.

Procedure

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

2. Enter the name for the group.

Note

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

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

The /newgroup is listed in the Groups panel.

4. To add a sub-group to a group, select a group (which will be the parent group) from the Groups panel, select Add, enter a name for the sub-group, and select Save.

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

5. After a DD system has been added to DD Management Center, it can be added to a group. Select the target group from the Groups panel, and select Add. In the Add Group window, select a DD system from the Available Systems panel, select > to move the system into the Systems in the group panel, and select 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 control to display the group assignments.

Adding Properties To help with searching, filtering, and organizing, you can add properties for DD systems, for MTrees, and for Replication pairs.

For example, you could assign properties to help filter the list of DD systems in the Inventory > Systems page and narrow the scope of output produced by a dashboard widget or generated report.

When a DD system is added to DD Management Center, a set of default administration properties (DD system model, DD OS version, domain name, and data center) is automatically added.

You can add and assign other properties as needed.

The following procedure describes how to add a property; there are other procedures for actually assigning the value to the property.

Procedure

1. Select Administration > Properties. At the top right, select one of the three tabs (System, MTree, or Replication), and select Add.

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

l String Allows a string of up to 256 characters to be set when assigning the property, for example, you could name the property Comments, and then someone could enter Waiting for Tom's response, Not ready yet, etc.

Getting Started

Adding Properties 21

l Boolean Creates a condition where you can assign one of two values, for example, you could name this property Restored?, and then the a value could be True or False, or Yes or No.

l Fixed-value String Lets you provide a name and specific values for the property, for example, Department could be the name, and then Finance, Human Resources, Marketing, etc., could be the values. Selecting the option Allow multiple types lets you assign more than one value for a property to a DD system, or MTree, or Replication pair.

3. Select Add.

After you finish

After properties are created, you can assign them to an object.

Adding (Registering) Data Domain Systems to DDMC Before you begin

Before you can manage a Data Domain system (DD system) in DD Management Center, you must add (register) it to the inventory with the following procedure.

A maximum of 100 DD systems can be added to a DD Management Center.

Groups of up to 20 systems can be registered at one time.

Procedure

1. Navigate to the Inventory > Systems page.

2. Select the Add (green + sign) control. Enter the following for the first DD system, then select Add to continue adding systems (up to 20 systems total). Make sure the box next to the system being added is checked. Select Register to continue:

l Host name (required) Enter the fully-qualified host name (use alphanumeric characters, dashes, periods, and underscores) or IP address. Ensure that the host name and the DNS name for the DD system match; a mismatch may cause problems with backup software.

l Sysadmin Password (required) Enter the sysadmin password used on the DD system (required).

l Firewalls (optional) Enter the inbound and outbound IP address (or host name) and port settings used by the firewall. If this option is selected, and you do not change the port setting, the default (3009) is used. If you do change it, the port number must be between 1 and 65535. The default port settings let DD Management Center communicate with the DD system. If the ports have been changed on the firewall or the DD system, they should also be updated here.

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

3. The status page reports the success and/or failure of the additions. In the event of an error, select Back to return to the first page to display error messages and correct errors, or to delete the system. When you have fixed all of the errors, select Next to continue to the Properties page or Close to quit. (The Next button will be disabled until all of the errors are corrected.)

Getting Started

7. Select 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.

After a DD system is added to DD Management Center, all historical information for that DD system is copied to DD Management Center. Then, anytime operational data changes on a DD system, the DD system notifies DD Management Center, which immediately polls the DD system to get the latest operational data.

Common Causes of Errors While Adding Systems The following checklist may help you resolve some errors that can occur when trying to add a DD system to DD Management Center:

l Make sure the DD system is online. A DD system must be online in order to be added to DD Management Center.

l If you specified a port number in the firewall settings, make sure it is correct.

l Make sure you have added the DD Management Center to the DD system as a host. Also, if the system is a DDVE, make sure the system has been added as a host on DD Management Center. (Log into the system, and in ddsh, use net hosts addIP hostname ).

l Make sure there are no networking issues preventing communication between the DD Management Center and the DD system.

l If you specified a host name for the DD system, make sure the host name can be resolved in your name space (DNS).

l Make sure the password entered for the system is correct.

l Make sure the DD OS version of the DD system is supported by your current version of DD Management Center (see the appropriate EMC Data Domain Management Center Release Notes).

l Make sure the DD system is not already managed by another DD Management Center. You can first delete the system from the original DD Management Center, or you can select the Override adding systems check box. The system will be added to the new DD Management Center, but the systems status will be changed to unmanaged on the original DD Management Center, and data collection will be suspended for that system.

Managing Groups Although group creation and modification can be performed only by the DD Management Center system administrator, any user can apply group designations to their DD systems, and can see the complete group structure, although RBAC (role-based access control) permissions control the systems that are displayed for each user.

Any permissions that are applied to a group affect all DD systems in that group. A lock image is added to the groups folder icon when permissions are directly applied to that group.

Use the Administration > Groups page to perform group management:

l Use Add to create groups or to add DD systems to existing groups.

l Use Delete to remove DD systems from the group-level organization. (You cannot use delete to remove systems from a group. But you can edit the group, and remove systems by selecting them in the right panel and selecting the left-pointing arrow)

l Use Edit on a selected group to modify the presence of DD systems within that group or the name of the group.

Note

Groups cannot be dragged and dropped into a different location; they must be changed with the Edit function.

Managing Replication Lag Threshold Policies Replication lag threshold policies warn you when replication pairs do not complete replication within a set amount of time.

By assigning a replication lag threshold policy, you are assured that notifications will be displayed in the Replication > Automatic page and the Top Replication Lags and Replication Lag Status widgets when the replication has not completed within the time periods you have set for Warning and Critical levels.

The default policy level for Warning is 24 hours, and the default for Critical is 48 hours.

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, or target the DD systems to be monitored for Dashboard Widgets. The Filter (funnel-shaped) control appears on pages and dialogs whenever a filter can be used. The drop-down menu on the Filter control allows you to select the groups, properties, DD systems, or rules to 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.

The Filter by rule option lets you 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 drop-down menu, select Filter by rule.

2. In the Filter by Rule dialog, provide a name for the filter.

3. Using the selection menus in the Match the following 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 (System, Group, Model, OS, Domain Name, etc.) and a logic condition (contains, does not contain, is, is not, etc.), 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 needed, add more statements with the Add row (+) control, or add conditions to the rule using the Block (...) control, which adds the choice of All or Any to the Match the following area), and create additional statements.

5. Select the Save (disk) control to make this filter available from the Filter menu list or select 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.

Monitoring Systems with DD Management Center 29

How DD Management Center Helps You Monitor Systems The monitoring tools of DD Management Center let you examine a wide array of operational information about managed Data Domain systems.

After a Data Domain system (DD system) is added to DD Management Center, all historical information for that system is copied to DD Management Center.

When operational data changes on a DD system, the DD system notifies DD Management Center, which immediately polls the DD system to get the latest operational data.

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 visual using charts, graphs, and color coding to help you interpret essential data points and easily notice alerts 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 and 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 and historical data and perform capacity predictions based on usage trends.

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

In addition to data provided on the 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 of interested parties.

DD Management Center Data Retention Policy DD Management Center maintains up to ten years of performance and capacity measurements for the DD systems it is monitoring. Data from the DD systems are consolidated into hourly sample points, generally collected at 30 minutes past the hour. The hourly samples are consolidated into daily samples, where a day is considered to run from Noon to Noon. Daily samples are further consolidated into weekly samples, where a week begins on Sunday.

To reduce the amount of space needed to store this historical data, DD Management Center periodically discards older samples. The number of samples retained depends on the nature of the data and whether the sample is hourly, daily, or weekly data. The following table shows the length of time that DD Management Center retains each sample.

Table 3 Data Retention Policy

Type of Data Keep Hourly Samples for

Finally, DD Management Center retains up to 2,000 historical alerts from each DD system being monitored.

DD Management Center Space Projection Algorithm DD Management Center uses a sophisticated algorithm to project growth in space usage and to predict when a DD system will run out of space. This algorithm was developed and verified using years of autosupport reports and should be quite accurate.

The goal of the algorithm is to compute a linear projection of space growth using an optimal set of recent data points. The data history is scanned to find the projection with the best fit (that is to say, the regression with the highest R2 value). After the best fit is determined, the projection must pass these validation tests to ensure that the prediction is accurate:

1. DD Management Center must have at least 15 days of historical data.

2. The regression R2 value must be at least 0.9 or higher.

3. The slope of the regression must be positive (that is, space usage is growing, not shrinking).

4. Time-to-full must be less than 10 years in the future.

5. The DD system must be at least 10% full.

6. The most recent data sample must be within 5% of the projection.

Combining all of these validation criteria accounts for typical DD system usage behavior, such as space becoming free after a cleaning cycle, jumps in usage as new backup loads are stored on the DD system, and space becoming free when backups are deleted.

Performing Daily Monitoring Using DD Management Center to perform daily monitoring of your site lets you check for unusual activity before it becomes a serious problem.

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

Checking Dashboard Status Widgets The Dashboard > Monitoring widgets (Current Health Status, Active Alerts, etc.) provide an overview of key performance indicators for your monitored DD systems. Widget functions let you check the health and status of DD systems and alert you to storage capacity threshold warnings and replication lags or failures.

The graphs, dials, and color-coded alerts make it easy to spot system operational problems. 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.

Monitoring Systems with DD Management Center

DD Management Center Space Projection Algorithm 31

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

If any of its monitored systems are not online, a Status button appears at the top right corner of a widget (except for Active Alerts). Selecting this button shows the count of systems with connection issues. Selecting the Show Health Status link opens the Health > Status page, where a list of these systems is displayed.

Checking Health Status The Dashboard health status and alerts widgets highlight systems that are reporting major reachability or operational problems. And if there are problems, the widgets provide drill-down links to system details.

Current Health Status The Current Health Status widget highlights unreachable systems and systems having problems with file system and replication operation, alerts, and data transmission protocols. The widgets show All Normal or show a count of systems exhibiting problems.

l Selecting the system count for each category navigates to the Health Status page, filtered to display the status of only that widgets systems.

l Selecting the banner for unreachable systems navigates to the Health Status page to show the status of just the unreachable systems.

l The marker for All Normal status has no navigation or drill-down behavior.

Active Alerts The Active Alerts widget displays a tally of systems with outstanding alerts for Emergency & Alert, Critical & Error, and Warning, using color-coded bar graphs.

l The length of the bar shows the total number of alerts, while color and symbol provide visual clues.

l Selecting the alert bar takes you to the Alerts page, filtered by the widgets configured filters and the type of alert category.

Checking System Capacity The System Capacity widgets help you to spot shortfalls in overall managed storage capacity and monitor managed system storage usage.

Capacity The Capacity widget displays systems that are nearing warning or critical storage capacity levels.

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

Space Usage The Space Usage widget lets you monitor aggregate totals of storage levels for all of 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. You can also check pre-compressed space usage and compression ratios to verify that deduplication is working as expected.

Checking Replication Progress The Replication widgets provide replication status, problems, and statistics.

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

Monitoring Systems with DD Management Center

32 EMC Data Domain Management Center 1.2 User Guide

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 shown, along with the lag trend for that pair (increasing, decreasing, or holding steady). Select a system entry to open the Replication > Automatic page, showing all pairs originating from that system.

Replication Lag Status by Pairs The Replication Lag Status by Pairs widget shows the count of replication pairs exhibiting Critical, Warning, and Normal threshold levels, based on the assigned policies. Selecting a bar navigates to the Replication > Automatic page, showing all pairs with that severity.

Checking Alert Notifications For new, unacknowledged alerts on systems you are authorized to manage, always check the Notification Area, located in the lower left of the Status Bar (the bottommost border of the DD Management Center window).

This Notification Area is not constrained by filter settings that are active, that is, it displays notifications of alerts for all of the systems you are authorized to manage.

The New Alerts area shows the current unacknowledged Emergency, Error, and Warning level alerts. Click anywhere on the New Alerts area to display a pop-up reporting the severity, system name, and class of the new alert. After the pop-up has been displayed, the alerts notification is removed from the Alerts Notification area.

To see the alert details, select the Show me these alerts link to open the Health > Alerts page, where the table is filtered to show only the new alerts.

Checking Health: Status For operational problems, check the Health > Status page.

Use the Systems/Groups/Tenants icons at the top right of the page to toggle page content to show all DD systems and DD systems organized by group or tenant assignment.

Using Graphs to Chart Performance To chart historical activity for the CPU utilization and throughput of the file system, protocol, and replication activity of a Data Domain system (DD system), check the System Details > Charts page.

With this tool, you can graph a systems resources (CPU utilization and network throughput) to identify:

l whether a systems resources have been overloaded for significant time periods

l the time frames and systems to consider for a new backup or replication

l whether more systems are required

Checking System Bandwidth To see if a Data Domain system (DD system) is experiencing bandwidth related bottlenecks, go to the System Details > Charts page, and select the Network throughput chart.

Determine how much network bandwidth is being used by DD systems sharing the same subnet to see if any are using more than expected or allowed by IT departments.

Performing Capacity Monitoring Use the Capacity pages to view information about storage utilization, by toggling between the Data Domain systems and MTrees being managed by DD Management Center.

You can check the current and historical space consumption, as well as estimate projected near-term future storage needs.

Checking System Capacity Utilization The Capacity > Utilization page presents storage usage amounts for monitored systems (default), or their MTrees. These selections can be viewed either by system or MTree name or by configured group. Each row in the table shows usage levels for a managed system or MTree, and aggregated totals are presented as the last row of the table. Selecting multiple systems displays their aggregated details.

This information gives you the ability to:

l Monitor the capacity of logically grouped or single systems to track usage and identify the systems that are using capacity too quickly

l Identify systems that have used up all their storage space

l Identify systems that have deviated from their norm for compression ratio, etc.

l Identify systems as targets for new back ups, replication, and migration

l View how much data was written during a timeframe, such as a back-up cycle, and determine how much it has been compressed

l Identify when garbage collection runs and how much space is reclaimed

l For Extended Retention systems, identify how much space is available and used on the Archive and Active tiers, and how well it is compressed

Checking Disk Space Usage Trends To monitor disk space usage trends, check the Capacity > Utilization page.

The Space Usage and Consumption tabs in the Charts panel provide information about:

Monitoring Systems with DD Management Center

Performing Capacity Monitoring 35

l Systems that are consuming space at a rate significantly greater or less than their historical norm

l Total capacity, amount consumed, and compression ratio (aggregate) for a group of systems

l Data ingest rate for a group of systems, for example, the total data ingest rate for the last 24 hours

l Systems that are out of space or critically low on space

l The amount of data that was backed up the previous night (24 hour period), and the compression ratio for a group of systems

l The last time that garbage collection was run and how much space was reclaimed

Check the Capacity > Projected page to:

l Predict when systems will run out of storage space or reach a critically low point

l Determine future capacity needs by projecting historical and current trends

l Determine targets for migration by projecting the systems that are filling up versus the same model systems that will have space available

Performing Replication Monitoring The Replication pages let you check the status of managed Data Domain system (DD system) replication and file replications by viewing pairs, cascaded replications, and topology charts. You can:

l Find status problems by selecting Sort Descending on the Status column to bring replication pairs with errors to the top of the table.

l On the Replication Automatic page, select Sort Descending on the Lag and Lag Trend columns to bring replication lag trends and lag time over critical and warning thresholds on DD systems to the top of the table. If replication is not working because of an error, the lag trend value for replication will be empty.

l On the Replication Overview page, select the Topology tab to visually check the operational status of connections, clicking the color-coded status indicators of arrows between systems to view details; and hovering the mouse to view details. Use controls to zoom in and out, and expand and collapse the contents of configured contexts on systems.

l Drill down (double-click a pair) to see status and details for a replication pair on the Cascades view

Monitoring Status with Reports Reports compile information for areas of interest on managed systems and are generated based on three default template types (capacity, replication, and status) for DD Systems, and on two default template types (status and usage) for Secure Multitenancy (SMT).

The template configures the reports content, schedule, and email distribution.

The launched version of DD System Manager actually runs on DD Management Center and not on the DD system, thereby giving you centralized, secure, and simultaneous administration for multiple DD systems.

Note

Launching from DD Management Center, v1.2, will bring up DD System Manager, v5.5.0. Any new features introduced in releases later than 5.5.0 will not be displayed.

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

l Health > Alerts

l Capacity > Utilization

l Capacity > Projected

l Inventory > Systems

l Replication Pair Details Lightbox

l 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 DD 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 DD system is opened).

The launched DD System Manager appears the same as a native DD System Manager session, except the navigation panel and Reports and Task Logs tabs are omitted. The banner shows the DD Management Center name, and the DD System name, OS release, and model type, as well as your management role (admin, etc.).

Note the following about launching DD System Manager from DD Management Center:

l You can launch DD System Manager only for a system for which you have an admin role.

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

n The admin role is required for replication configuration and IPMI configuration.

n The Security Officer role is not supported.

l The inventory of DD systems on DD Management Center is used.

n The DD systems shown are based on your effective permissions.

n Only replication source and destination systems registered with DD Management Center are shown.

l You do not need to open any additional firewall ports for the session (that is, after a DD 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 (DD systems) can be upgraded from DD Management Center. You must have admin rights on the DD system to upgrade and manage upgrade packages, and you must have admin rights on DD Management Center to manage upgrade packages.

To perform a DD OS upgrade, you must

l Obtain a DD OS upgrade package, by downloading an upgrade package form the EMC Online Support site.

l Upload the DD OS upgrade package to DD Management Center using the Inventory/ Systems Manage Packages dialog.

l Perform the DD OS upgrade on the DD system.

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 (DD systems).

You first download the upgrade package from the EMC Online Support 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 a DD system or systems.

3. The banner will display Upgrade if the currently selected system(s) allow an upgrade. In this case, to manage packages, use the drop-down for Upgrade to select Manage Upgrade Packages. If the currently selected system(s) do not allow an upgrade, the banner will display Packages, and selecting this will present the Manage Upgrade Packages dialog.

4. Select the appropriate option from the Manage Upgrade Packages dialog:

l Select the EMC Online Support link to obtain an upgrade package to store locally.

l To upload a package to the DD Management Center inventory, select Add and browse to the local drive to select the package.

Results

After 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 (DD 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.

Managing Data Domain Systems

Upgrading Data Domain System Software 41

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

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

The body of the window shows any warnings or errors. All errors must be removed before the upgrade is allowed. Errors can be removed by removing the offending system from the list, or possibly by changing the target upgrade version. You may choose to correct the condition separately, and try again later. Warnings such as those for resulting incompatible versions in a replication pair will not disallow the upgrade.

Also, if there are no packages in the DD Management Center inventory, there will be a link above the table on the right that will take the user to the Manage Upgrade Packages dialog.

5. Select Upgrade to upgrade the selected systems.

If systems are not in an acceptable managed state (for example, unreachable, suspended, upgrading) 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 long time. 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 the Administration > Settings page, and select the Access > Local Users tabs.

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

These users can log into DD Management Center, but cant see any other systems. You can add permissions to view (user role), administer (admin role), or take snapshots (backup operator) for groups and Data Domain systems (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 these users may view the systems.

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

4. Select where to add the permission:

l Add permissions to systems Select this option, and from the list of managed DD systems, select the check boxes of the systems where the permissions are to be assigned.

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

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

Managing Data Domain Systems

42 EMC Data Domain Management Center 1.2 User Guide

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

7. Select Add.

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

After you finish

To simplify the management of permissions:

l It is recommended that the use of the admin role for the DD Management Center be minimal.

n The admin role can manage all DD systems in the DD Management Center inventory. In addition, the admin for the DD Management Center configures the DD Management Center properties and groups and assigns its permissions.

n Configure most logins for DD Management Center with the user role.

l Use NIS user groups for permissions this simplifies the process for adding, removing, and modifying users without changing the permission assignment.

l 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.

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

n Assign lower level permissions toward the root of the Group hierarchy.

n Assign higher level permissions toward the leaf of the Group hierarchy.

n 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:

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

Use Central Administration:

l 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.

How DD Management Center Helps You Monitor SMT DD Management Center can configure and monitor secure multitenant DD Boost backup and replication storage on multiple DD systems.

In a secure multitenant environment, storage administrators (landlords) and backup administrators (tenants) cooperate to allocate and manage storage, as follows:

1. The storage administrator creates tenants on DD Management Center. For example, the storage administrator in a corporate IT organization might create a tenant for the backup administrator in the finance department.

2. The storage administrator creates one or more Tenant Units on DD systems to serve as virtual containers for each tenant.

3. The storage administrator creates one or more MTrees and/or DD Boost Storage Units.

4. The backup administrator configures backup software to use the MTrees in the Tenant Unit as storage targets.

For additional information, see the Working with Secure Multitenancy chapter of the EMC Data Domain Operating System Administration Guide.

DD Secure Multitenancy Overview EMC Data Domain Secure Multitenancy (SMT) provides secure storage consolidation in Protection Storage.

Segregating, isolating, and protecting data of multiple customers on a single DD system is the main feature of SMT.

Multiple tenants can simultaneously reside on a single DD system, but the activities of one tenant cannot be detected by another.

Within an enterprise, a tenant may consist of one or more business units or departments on a DD system configured and managed by IT staff.

l For a business unit (BU) use case, the Finance and Human Resources departments of a corporation could share the same DD system, but each department would be unaware of the presence of the other.

l For a service provider (SP) use case, the SP could deploy one or more DD systems to accommodate different Protection Storage services for multiple end-customers.

Both use cases emphasize the segregation of different customer data on the same physical DD system.

SMT Components Defined This section provides definitions for some of the components in a Secure Multitenancy (SMT) environment.

MTrees MTrees are logical partitions of the Data Domain file system and offer the highest degree of management granularity, meaning users can perform operations on a specific MTree without affecting the entire file system. MTrees are assigned to Tenant Units and contain a Tenant Unit's individualized settings for managing and monitoring SMT.

Multitenancy Multitenancy refers to the hosting of an IT infrastructure by an internal IT department, or an external service provider, for more than one consumer/workload (business unit/

Administering SMT using DD Management Center

46 EMC Data Domain Management Center 1.2 User Guide

department/tenant) at the same time. Data Domain's Secure Multitenancy (SMT) feature enables data-protection-as-a-service.

Role-based Access Control (RBAC) Role-based Access Control (RBAC) offers multiple roles with different privilege levels, which combine to provide the administrative isolation on a multitenant DD system. (The next section will define these roles.)

Storage Unit A Storage Unit is an MTree configured for the DD Boost protocol. Data isolation is achieved by creating a Storage Unit and assigning it to a DD Boost user. The DD Boost protocol permits access only to Storage Units assigned to DD Boost users connected to the DD system.

Tenant A tenant is a consumer (business unit/department/customer) who maintains a persistent presence in a hosted environment.

Tenant Self-Service Tenant Self-Service lets a tenant log in to the DD system to access the Tenant Units assigned to him or her and perform their own administration and reporting for their own environments. Tenant Users and Tenant Admins will, of course, have different privileges, as described in the next section.

Tenant Unit A Tenant Unit is the partition of a Data Domain system that serves as the unit of administrative isolation between tenants. Tenant Units are secured and logically isolated from each other, which ensures security and isolation of the control path when running multiple tenants simultaneously on the shared infrastructure. Tenant Units can contain one or more MTrees, which hold all configuration elements needed in a multitenancy setup. Users, management-groups, notification-groups, and other configuration elements are part of a Tenant Unit.

How Data Domain Uses RBAC in SMT Within Secure Multitenancy (SMT), the ability to perform a task depends on the role assigned to a user. Each user role has a unique set of permissions enforced at the infrastructure level by the DD system using role-based access control (RBAC).

Note

These roles, including Management Groups, are enforced by the Data Domain system, not DD Management Center.

admin role A user assigned the admin role has full access to the entire DD OS command set and can perform all administrative operations on a DD system. The admin can also perform all SMT administrative operations on a DD system, including setting up SMT, assigning SMT user roles, enabling tenant self-service mode, and others. SMT commands are included in the DD OS command set. In the context of multitenancy, the admin is typically referred to as the landlord. In DD OS, the role is known as the sysadmin.

tenant-admin role A user with a tenant-admin role can perform the designated operations only when the Self-Service option is enabled on the specific Tenant Unit. Responsibilities include scheduling and running a backup application for the tenant, and monitoring resources and statistics within the assigned Tenant Unit. Tenant-admins ensure administrative separation when tenant self-service mode is enabled. In the context of multitenancy, the tenant-admin role is typically referred to as the backup admin.

Administering SMT using DD Management Center

DD Secure Multitenancy Overview 47

tenant-user role The tenant-user role allows users to monitor the performance and usage of SMT components on their assigned Tenant Unit only, and only when tenant self-service is enabled. Tenant-users may run the show and list commands.

none role A user with a role of none is not allowed to perform any operations on a DD system other than changing their password and accessing data using DD Boost. However, after SMT is enabled, the admin can select a user with a none role from the DD system and assign them an SMT-specific role of tenant-admin or tenant-user. Then, that user can perform operations on SMT management objects.

management groups Backup service providers (BSPs) can use management groups defined in a single, external Active Directory (AD) or NIS to simplify managing user roles on Tenant Units. Each BSP tenant may be a separate, external company and may use a name-service such as AD or NIS.

With SMT management groups, the AD and NIS servers are set up and configured by the admin in the same way as SMT local users. The admin can ask their AD or NIS administrator to create and populate the group. The admin then assigns an SMT role to the entire group. Any user within the group who logs in to the DD system is logged in with the role assigned to the group.

When users leave or join a tenant company, they can be removed or added to the group by the AD or NIS administrator. There is no need to modify the RBAC configuration on a DD system when users who are part of the group are added or removed.

Use Cases for SMT The following use case examples summarize how Secure Multitenancy (SMT) can be deployed in protection storage infrastructures.

Local Backup In the local backup use case, a protection storage infrastructure is shared across clients and deployment is local to the enterprise. The on-premise IT staff uses each Tenant Unit to back up the data of a specific business unit.

Replicated Backup In the replicated backup use case, the tenant performs local backups at their physical site, but does not want to own or manage a remote site for disaster recovery purposes. For this type of tenant, service providers can host multiple tenants, each replicating to their own Tenant Unit, to provide replicated backup services on a shared Data Domain backup appliance platform.

Remote Backup In the remote backup use case, a client does not perform local backups at the physical site. Instead, the client performs direct backups over the WAN to a hosted backup IT environment managed by a service provider or a hosted provider. Remote backup is used for traditional client-based backup and application-direct backup.

Multi-User DD Boost and Storage Units in SMT Multi-User DD Boost refers to the use of multiple DD Boost user credentials for DD Boost Access Control, in which each user has a separate user name and password.

A Storage Unit is an MTree configured for the DD Boost protocol. A user can be associated with, or own, one or more Storage Units. Storage Units that are owned by one user cannot be owned by another user. Therefore, only the user owning the Storage Unit can access the Storage Unit for any type of data access, such as backup/restore. The number

Administering SMT using DD Management Center

48 EMC Data Domain Management Center 1.2 User Guide

of DD Boost user names cannot exceed the maximum number of MTrees (current maximum is 100).

Each backup application must authenticate using its DD Boost user name and password. After authentication, DD Boost verifies the authenticated credentials to confirm ownership of the Storage Unit. The backup application is granted access to the Storage Unit only if the user credentials presented by the backup application match the user names associated with the Storage Unit. If user credentials and user names do not match, the job fails with a permission error.

Managing Tenant Users and their Privileges There is no direct way to create a tenant user. The only way for a tenant to have users is by association with its Tenant Units. Tenant users are all users in their Tenant Units.

You can create a user with the DD System Manager (see the EMC Data Domain Operating System Administration Guide) or the Command Line Interface (CLI) (see the EMC Data Domain Operating System Command Reference Guide).

Adding a user with an association to DD Boost data access or tenant self-service using the CLI can be dangerous because of cross-tenancy issues. The CLI will not validate users belonging to other tenants when adding DD Boost data access users or tenant self- service users to the current tenant.

You can also create local users with DD Management Center. If you create a local user with a role of none using the DD System Manager or CLI, the user will appear in the DD Management Center list of available users to be added for DD Boost data access and/or tenant self-service.

Overview of Using SMT with DD Management Center In DD Management Center, the Secure Multitenancy feature is administered by selecting Administration > Multitenancy.

The Administration Multitenancy page shows a Tenant tree on the left, from which you can create and manage tenants, Tenant Units, and provisioned storage.

Above this tree are controls to Add (green +), Edit (pencil), and Delete (red X) tenants and/or Tenant Units (depending on what is highlighted in the tree), as well as a Tenant (Unit) Details (blue i) icon that displays the Tenant (Unit) Details Lightbox (again depending on what is highlighted). You can also right-click on each node in the tree to perform these functions, as well. All of these actions are controlled by RBAC (role-based access control).

Also in the tree, each node has a control to its left, indicating its Warning or Offline status. This status rolls up to the tenant and all tenant nodes. Additionally controls for creating, editing, or deleting states are displayed while each operation is in progress. Some actions may not be allowed, depending on the different state or status of the nodes. If there are Tenant Units under a tenant with the same name, an information icon is displayed for the tenant node.

The All Tenants node is always displayed and lets you create tenant objects.

The Unmanaged node is displayed only if there are unmanaged Tenant Units available. The only actions allowed on the Unmanaged node and the Unmanaged Tenant u=Units are Add all to Tenant and Add to Tenant, respectively, and are available only through the right-click context menus.

To the right of the tree is a summary.

When All Tenants is selected, the summary shows the total number of tenants, Tenant Units, and host systems. You can see if any of the tenants or Tenant Units are offline or

Administering SMT using DD Management Center

Managing Tenant Users and their Privileges 49

have configuration problems in different severity panels. You can also see the number of unassigned Tenant Units.

When you select a tenant or Tenant Unit, the summary includes (depending on the item) the name, status, administrator name and email, host systems, data center location, alerts, and MTree and storage information, DD Boost Users, Tenant Self-Service information, and Report schedule and recipients.

To generate reports about tenants or individual Tenant Units, select Reports > Management.

To see the general health for tenants and Tenant Units, select Health > Status, Health > Alerts, and/or Health > Jobs.

To changed a Data Center Location, select Administration > Properties and edit the Data Center property. Note that each DD system must explicitly be assigned a value for Data Center in Administration > Systems. If a DD system has a Data Center property assigned, it will be grouped under All in the Create Tenant Unit wizard.

Using DD Management Center as a Storage Administrator in a Multitenant Environment Storage administrators are the landlords for backup operators (tenants). Storage administrators install and configure DD system hardware and software and use DD Management Center to provision and assign storage to the tenants that they support.

Some of the tasks and goals of the storage administrator in a multitenant environment include:

l Migrate users from multiple small DD systems to one or more larger systems.

l Isolate each tenant's data from other tenants who share storage on the same physical DD system.

l Monitor and manage the space usage and performance of each system.

l Monitor and manage the space usage by, and performance provided to, each tenant. This ensures that the storage administrator meets the requirements of the service level agreement with each tenant.

l Group together tenants with similar characteristics on the same physical system to gain more cross deduplication.

l Charge tenants based on their space usage.

Using DD Management Center as Backup Administrator in a Multitenant Environment Backup administrators are the tenants in a secure multitenant environment. They are responsible for scheduling and managing backups and replication for their organization or department using the storage available in their Tenant Units.

Backup administrators can use DD Management Center to monitor the performance and resources of their Tenant Units, monitor replication, and generate reports.

Deleting Tenants When you no longer need to provide storage for an organization, you can delete the tenant that corresponds to that organization.

Before you begin

Navigate to the Administration > Multitenancy page.

To delete a tenant:

Procedure

1. Highlight the tenant in the tree, and select the Delete Tenant (red X) control at the top of the tree.

2. In the Delete Tenant dialog, you have two options:

l Remove all Tenant Units, which will preserve the data, so that the Tenant Unit may be assigned to another tenant. The Tenant Units will be moved to the Unmanaged Tenant Unit pool and will retain all MTrees/Storage Units associated with them.

l Destroy all Tenant Units, which will destroy all of the Tenant Units and any MTrees and Storage Units associated with them.

3. Select Yes.

NOTICE

Deleting a tenant cannot be undone from DD Management Center, so be very careful when performing this task.

Results

The tenant has been deleted from the tree.

What to do if delete Tenant fails When you try to delete a tenant, the operation may fail for a variety of reasons.

First, go to the Health > Jobs page, select the failed job, and observe the reason for the failure, which may include:

l The file system of one or more of the DD systems under the tenant is turned off.

l Some of the DD systems under the tenant are not reachable or are powered down.

l The DD Boost feature of one or more of the DD systems under the tenant is disabled or is not licensed.

You can manually fix these problems using both the DD System Manager and the DD Management Center command line interfaces (you need to fix them in both places, as they are DD system-related). Then, you can try to delete the tenant again using DD Management Center.

Creating and Managing Tenant Units This section describes how to create and manage Tenant Units.

Creating a New Tenant Unit with the Wizard You can create a Tenant Unit with the Create Tenant Unit Wizard.

Before you begin

Storage for a tenant is contained within a virtual partition called a Tenant Unit on a DD system. To assign storage to a tenant, you can use the Create Tenant Unit Wizard to

Administering SMT using DD Management Center

Deleting Tenants 53

create the Tenant Unit, provision storage, and assign the Tenant Unit to a tenant. You can also create an empty Tenant Unit for a tenant and provision storage later. Select Administration > Multitenancy. Then select a tenant, and the Add (green +) control.

You have three choices when creating a Tenant Unit:

l Create a Tenant Unit with manual provisioning, where you create/select the MTrees and Storage Units that will be associated with this Tenant Unit. You can also optionally create DD Boost Data Access users to go with the Storage Units.

l Create a Tenant Unit with automatic provisioning, where you can add new or existing DD Boost Data Access users to this Tenant Unit. This will allow backup software to create Storage Units that will be assigned to this Tenant Unit.

l Create an empty Tenant Unit, where you can provision the Tenant Unit later using the Edit Tenant Unit dialog.

Procedure

1. On the first page of the wizard, Identify Host System:

l For Tenant Unit name [which is required, as indicated with the asterisk (*)], enter a unique Tenant Unit name per system.

l For Administrator name (which is optional), enter the name of the backup administrator.

l For Administrator email [which is required, as indicated with the asterisk (*)], enter the email address of the backup administrator. This will be used to create a default Alert Notification list.

l For Datacenter location (which is optional), enter a location. The Tenant Unit will be created only on systems at this location. This is the same Data Center location from Administration > Properties. The administrator should populate the Data Center property with values (for example, Dallas, New York, etc.). When adding a system, this property should be set for the system, depending on its location (example, Dallas). After this value has been set for any system, it will show up in the drop-down list here (Create Tenant Unit). Selecting it will then filter and show all systems based on only that Data Center location property.

l For Size now (GiB) (which is optional), enter a number to filter systems that do not currently have sufficient storage capacity.

l For Size to grow (GiB) (which is optional), enter a number to filter systems that will not have sufficient capacity at a specified time in the future (set in the next field, Time to grow), based on capacity projections. The size to grow is actually the size to grow to by the specified time. For example, for a specified time of 6 months, if the size now is 1 GiB, and the size to grow is 2 GiB, in six months, the minimum capacity requirement would be 2 GiB.

l For Time to grow (which is optional), enter the time after which the Size to grow amount of capacity should be reached.

2. On the second page of the wizard, Select Host System, you will see systems that have enough logical capacity to host the Tenant Unit:

l Available now indicates systems that you can select now.

l Available in 6 months is displayed if you selected 6 months in the Time to grow field on the previous page, or did not explicitly select a value. Available in 12 months, Available in 18 months, or Available in 24 months is displayed if you selected those values in Time to grow. For example, for a specified time of 6 months, if the size now is 1 GiB, and the size to grow is 2 GiB, in six months, the minimum capacity requirement would be 2 GiB. Any system that has a lower projected capacity will be filtered from the list. Also, any system offline at the time, as well as any collection destination system, will be filtered from the list. Also, any

Administering SMT using DD Management Center

54 EMC Data Domain Management Center 1.2 User Guide

systems running a version prior to DD OS 5.5.x will be filtered from the list, that is, only systems running DD OS 5.5.x or later will be listed.

l Existing Tenant Units displays the current number of Tenant Units on this system.

l For systems with an information (blue i) control, you can hover to see a warning message explaining why a projection cannot be made.

l For the selected system, the charts at the bottom shows historical data, including throughput for selected connection port, CPU utilization for each system, and stream count. You can use this information to determine the best system on which to create the Tenant Unit.

3. The third page of the wizard depends on your previous choice. [Note that for Create an empty Tenant Unit, you will just go to the final page (step 4).]

a. For manual provisioning, you can create MTrees/Storage Units.

l MTrees/Storage Units can be added here, when creating a Tenant Unit with Manual Provisioning. You can also add then when editing a Tenant Unit.

l You can add new MTrees or Storage Units, or select from the Existing MTrees or Storage Units on the host system.

l You can also edit, unassign, or destroy MTrees or Storage Units from the same area.

l If an MTree or Storage Unit selection is disallowed, you can hover the mouse over it, to see more information.

b. For automatic provisioning, you can configure users for data access over the DD Boost protocol.

l You can add an existing local user or create a new local user and promote the local user to DD Boost user.

l You can delete the selected DD Boost User.

l The table contains DD Boost Data Access User names and the Storage Units count associated with the user.

l The information panel shows when one or more users is selected.

l The configuration is not changed until you select Create on the Summary page.

l If there are one or more local users in the list, the first local user in the list will be selected by default. If there are no local users in the list, the New local user will be selected. All selected users or newly created users will automatically be default Tenant Units.

l A warning will show if the current selected local user already has another Tenant Unit as their default Tenant Unit.

l The first entry in the Local user drop-down list is New local user, which lets you create a new local user and add it as a DD Boost Data Access user.

l When selecting New local user, the Add DD Boost Data Access User dialog will change to a create new local user form.

4. The fourth (final) page (third page for Create an empty Tenant Unit) of the wizard is a Summary, showing data from the previous pages.

l The Tenant Unit is not created until you select Create.

l You have the option to send an email to the Tenant Unit administrator on the successful creation of the Tenant Unit.

l Creating a Tenant Unit with any sort of provisioning (not empty) will automatically generate a pair of Report Templates (Status and Usage) and schedule them.

Creating a New Tenant Unit with the Wizard 55

l You may get one of two warnings: (1) You have not provisioned this Tenant Unit correctly. Add MTrees or Storage. (2) You have not provisioned this Tenant Unit correctly. Make this Tenant Unit the Default Tenant Unit for one of the DD Boost Data Access Users.

Results

The newly created Tenant Unit is added to the tree.

What to do if create Tenant Unit fails Creating a Tenant Unit may fail for a number of reasons.

It may fail for simple reasons such as a duplicate Tenant Unit name, or it may fail if there are network/connectivity issues, sudden system state changes, etc.

Within the create process itself, there may be failures where MTrees or Storage Units may fail to get created for one or more reasons, or DD Boost users may not get created.

Creating a Tenant Unit will succeed even if the configuration of an individual component like MTrees or DD Boost users fails. So, the final components of a newly created Tenant Unit might not match your specifications.

To see the success and/or failed information for each individual task, or if there is an inconsistency in what you expected and what was created, navigate to the Health > Jobs page, which has additional messages.

You must address the reasons for failure before trying to re-create a new Tenant Unit, or you risk seeing the same failure situations again.

l Destroy all storage, which deletes all MTrees and Storage Units associated with the Tenant Unit.

3. Select Yes to delete the Tenant Unit.

NOTICE

Deleting a Tenant Unit cannot be undone from DD Management Center, so be very careful when performing this task.

Administering SMT using DD Management Center

60 EMC Data Domain Management Center 1.2 User Guide

Results

The Tenant Unit has been deleted from the tree.

What to do if delete Tenant Unit fails When you try to delete a Tenant Unit, the operation may fail for a variety of reasons.

First, go to the Health > Jobs page, select the failed job, and observe the reason for the failure, which may include:

l The file system of the DD system on which the Tenant Unit resides is turned off.

l The DD system on which the Tenant Unit resides is not reachable or is powered down.

l The DD Boost feature of the DD system on which the Tenant Unit resides is disabled or is not licensed.

You can manually fix these problems using both the DD System Manager and the DD Management Center command line interfaces (you need to fix them in both places, as they are DD system-related). Then, you can try to delete the Tenant Unit again using DD Management Center.

Adding an Unmanaged Tenant Unit to a Tenant Working from the DD OS Command Line Interface (CLI), administrators can create Tenant Units without adding them to tenants. These Tenant Units are referred to as unmanaged. In DD Management Center, you cannot create an unmanaged Tenant Unit, but you can add an unmanaged Tenant Unit to a tenant.

Before you begin

Navigate to the Administration > Multitenancy page.

To add an unmanaged Tenant Unit (or Units) to a tenant:

Procedure

1. Select the Unmanaged node in the tree. A table is displayed on the right, which contains all unmanaged Tenant Units and the host systems on which they reside.

2. If you want to add all unmanaged Tenant Units to a tenant, right-click the Unmanaged node, and select Add all to Tenant. In the Add All Tenant Units dialog, select the tenant name, and select Add.

3. If you want to add only a specific Tenant Unit or Units to a tenant, go back to the table to select the check box or check boxes next to them. Or to select a single Tenant Unit, and see a summary about it, you can expand the Unmanaged list (if it is not already expanded), and select a single Tenant Unit.

4. At the top right, select the Add to Tenant link.

5. In the Add Tenant Unit(s) dialog, select a tenant name, and select Add. The Tenant Unit will be moved from the Unmanaged node to the selected tenant, in the tree.

After you finish

You may encounter a potential conflict when trying to assign a Tenant Unit. Suppose you have a DD Boost user, or tenant self-service user, configured under a current unmanaged Tenant Unit. If the same user is configured to the managed Tenant Unit of tenant T2, but you want to assign the Tenant Unit to tenant T1, this is considered a conflict and is not allowed.

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 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.

Viewing Route Information Procedure

1. Navigate to Administration > Settings > Network tab > Routes tab.

2. On the Routes page, view the configured static and dynamic routes (described in the following table), and create or modify routing information.

Table 7 Route Information

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 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 use 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. Also 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.

Checking SNMP Status and Configuration Navigate to the Administration > Settings > General tab > SNMP tab.

The SNMP page shows SNMP status and properties, and the SNMP V3 and SNMP V2C Configuration.

Managing Access to DD Management Center Access management includes viewing and configuring the services that provide administrator and user access to DD Management Center.

Roles Required for DD Management Center Tasks

Note

Since mutual trust is established between DD Management Center and the DD systems that it manages, if a user is added to DD Management Center with admin level access, that user can also access the managed DD systems (through ssh or by launching DD System Manager) to perform admin-level operations. Also, an admin-level user can perform an upgrade operation on a managed DD system. Therefore, you should give each new DD Management Center user the same consideration that you would a new DD System Manager user.

The ability to perform tasks on a DD Management Center page is role-based, and the roles available in DD Management Center are the same as those in DD System Manager:

l admin, that is, the DD Management Center Administrator. The admin can access all functions on a DD Management Center page.

l user, that is, a DD Management Center User. A user, which can be a stand-alone user or part of a group, has access to only certain functions on a DD Management Center page, based on the role assigned to that user or group.

The following table shows the actions available for each feature of DD Management Center. [This table is mainly provided to show when only the user role is required. The admin role can perform all tasks, as previously mentioned.]

Use the column controls to sort the alert list by severity, system name, post time, class, message text, and object ID. The System Name column includes a filter for entering system name text.

Alerts in the table can also be filtered by date controls (Last 12 hours, last 24 hours, last 7 days, last 30 days, all active alerts, and custom filtering).

Selecting an alert in the table shows descriptive information about the alert in the Details and the History panels.

To see a summary of the alert's history, select the More Details link to see a list of every occurrence of the alert at the site.

To investigate or resolve an alert on a DD system, open the DD System Manager by double-clicking the alert in the table, or use the Launch DD System Manager control, which is enabled when a Data Domain system alert is selected.

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 DD system. For example, the Report Generation task runs solely on DD

DD Management Center Graphics Reference

110 EMC Data Domain Management Center 1.2 User Guide

Management Center; other tasks, like Upgrade, run mostly on the DD system, but a skeleton process on DD Management Center keeps track of the task's progress. And still other tasks run mostly on DD Management Center (such as Adding Systems), but have subtasks that run on the DD system.

Note

Tasks that run on DD System Manager (native to the DD system) are not shown in the Jobs list only 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, have failed, or are still in progress. If no selection is active, no jobs are shown.

The displayed list of tasks is dependent on the role:

l A person with a User role on a DD system or DD Management Center sees only the tasks they initiated on that DD system or DD Management Center.

l An Admin on a DD system or DD Management Center sees all jobs on that DD system and DD Management Center.

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 by System (DD system) or MTree (tabs at top right). 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 Systems or Groups (toggle at top right). Selecting an entry in the systems table displays detailed connection status information immediately below the table.

When the Systems 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 can also filtered by an entered value (greater, lesser, or equal to entered value).

The MTree page displays the type of MTree (which can be sorted by ascending/ descending and filtered by MTree or Storage Unit), 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 be determined only over a time interval (last 24 hours, last 7 days, etc.), not for a point in time.

DD Management Center Graphics Reference

Capacity 111

Note

The Space Usage amounts may not exactly match capacity totals reported by 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 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 capacity terms, as introduced in the EMC Data Domain Operating System Administration Guide. See 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.

l 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).

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

l 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, by:

DD Management Center Graphics Reference

112 EMC Data Domain Management Center 1.2 User Guide

l Predicting when systems will run out of storage space l Determining future capacity needs by projecting historical and current trends l Estimating when a system will reach its system-specific warning/critical space usage

thresholds

This page also provides tabular information for monitored systems. Each entry shows the system name, model, OS version, and a connection status icon with a 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.

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

Table 29 Insufficient Data Messages

Forecast Engine Output DD Management Center Message

Insufficient capacity used The average space used in the last 7 days was less than 10%.

Negative slope There was a large recent drop in the amount of space used.

Date column data (Current, and those selected using the timeline) can be sorted by amount of Used Space, Free Space, % Used, and Size in ascending or descending order.

Use the slider controls on the timeline to increase or decrease the date span.

Highlighting a system in the list activates controls for examining system details and launching the DD System Manager.

Replication The Replication pages provide status and performance details about the replication pairs on managed DD systems. l The Replication > Overview > All Pairs page lists each monitored DD system that has

configured replication pairs. Expand an entry 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 applicable replications. 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

DD Management Center Graphics Reference

Replication 113

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.

l 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 is red when lag duration is greater than or equal to the Critical threshold and yellow for Warnings; hover over the cell for detailed information about the lag threshold), lag trend (increasing the 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 to see policy settings), bytes remaining, and status message text. The page-specific controls include Assign Properties 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.

l 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 (toggle at top right).

l 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.

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

For DD Boost (on-demand replication) monitoring, the DD system must be running DD OS 5.3.1 or later. 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.

DD Management Center Graphics Reference

114 EMC Data Domain Management Center 1.2 User Guide

Note

If the source or destination fields show an IP address instead of a host name, the DNS server configuration for the DD system must be modified. When configuring DD systems to monitor DD Boost (on-demand replication), ensure their DNS servers include configuration for both forward and reverse host name 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 instead of host names.

l The replication Pair Details control is active when a pair is selected and shows a lot of replication detail.

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

l The Export CSV file control sends the overview listing with performance data for the 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.

Topology When the Topology view is selected on the Replication > Overview page, it shows the relationships of the site's configured replication contexts and uses color-coded status 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.

DD Management Center Graphics Reference

Pairs 115

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. Selecting Pair Details opens the Replication Pair Details lightbox, which shows a lot of information about the replication pair last transfer status, source and destination systems, settings such as encryption, operational status, and color-coded icons showing capacity levels.

At the bottom of the page 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). Hover 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, here are some possible reasons:

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

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

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

Select 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.

Reports The Reports feature lets you compile specific information about managed systems, based on three default template types (capacity, replication, and status) for either System or Multitenancy.

A wizard helps configure a template for the reports content, schedule, and email distribution. A report can be generated directly from a template ad hoc and not saved, or it can be saved as a template for generating reports for later use.

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.

DD Management Center Graphics Reference

116 EMC Data Domain Management Center 1.2 User Guide

Note

For DD Boost (on-demand replication) monitoring, the DD system must be running DD OS 5.3.1 or later. 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.

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

Use the Create Report Template wizard, which is started with the Add control, to create a template to generate reports.

After 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 a 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 pages (Assigned, Groups, Systems, Users) show the permissions of DD Management Center users by assigned role.

Permissions are a triangle of three components:

l The managed object (groups or systems)

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

l 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.

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

Groups On the Administration > Groups page, 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 Groups 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 information icon is displayed for systems that reside in more than one group; when you hover over it, the groups are listed.

There is only one root (/), but it can contain multiple groups (in the Add Group dialog, 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.

DD Management Center Graphics Reference

Management 117

The structure of the hierarchy or the contents of the groups are changed with the Group edit controls (Add, Edit, and Delete).

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.

Table 30 Groups Page Icons

Controls Name Description

Group Symbolizes a group containing DD systems or other groups. When subgroups are present, the expander icon is displayed to the left of the folder. Selecting the folder displays the members of the group in the Group Details panel.

Group with permissions applied

Indicates that this group is controlled by access permissions.

Membership details Appears when a DD system belongs to more than one group. Hover to view the names of groups of which this DD system is a member.

Properties Properties provide information to help you classify systems and the data contained in MTrees and Replication contexts for searching, filtering, and organizing.

For example, you could assign properties to help filter the list of DD systems in the Inventory > Systems page and narrow the scope of output produced by a dashboard widget or generated report.

Properties are organized and managed by type (System, MTree, and Replication), and selecting a property type displays a catalog of its active properties. The value of a property can be a string, a number, a boolean, or a fixed-value string.

Select Administration > Properties to see a list of all assigned properties for System, MTree, and Replication.

The following table shows the controls for the different types of properties.

Systems The Inventory > Systems page lists the DD systems being managed by DD Management Center. The columns show the system's host name, status, model, and OS. You can customize the display of these columns using the Show Columns control, at the right. If properties have been created for a system, you can also add those as columns.

Selecting the system status icon for a system with a connection issue produces a detailed status notification panel at the bottom of the systems list.

Selecting a DD system in the table provides additional details for the system at the bottom of the page. They include: l Configuration Shows the system's host name, time zone, inbound and outgoing

firewall IP address and port settings, as well as warning and critical threshold level settings for the system's storage capacity.

l Properties Shows the properties assigned to the system and their values. To assign a property or change an existing property's value, select Edit, then the Properties tab, and enter the value in the property field.

l Groups Shows the names of groups of which this system is a member. To assign a group to this system or remove the system from a group, select Edit, then the Group tab, and select/deselect the group name.

Note

If the table is empty, you need to add systems to the DD Management Center.

For any icon for systems exhibiting abnormal status, select the icon or system entry to see a status banner detailing the problem.

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 also included on this page.

Communication Between 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.

DD Management Center Graphics Reference

Settings 119

After contact is established with the DD system, its hostname is used from that point onward, 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:

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

l 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:

l Use the command net pinghostname 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.

l 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.

DD Management Center CLI Reference

This appendix provides a reference for the CLI (command-line interface) of the DD Management Center.

DD Management Center CLI Reference 121

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 section describes the DD Management Center CLI.

The main user interface for DD Management Center is the web-based graphical user interface (GUI). It is recommended 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:

l 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.

l 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 instead of a storage appliance.

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

l 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 hostname [force] [inbound-proxy proxy-host [inbound-proxy-port proxy-port]] [outbound-proxy proxy-host [outbound-proxy-port 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:

1. Verify that the certificate obtained from the host is valid.

2. Enter the sysadmin password for the system being added to management.

DD Management Center CLI Reference

122 EMC Data Domain Management Center 1.2 User Guide

Argument Definitions

force If the system is already being managed by another DD Management Center, the current DD Management Center assumes management of the Data Domain system from the other DD Management Center, and the Data Domain system entry in the other DD Management Center is placed in the unmanaged state. If the system is already being managed and you omit this argument, the command fails.

hostname The hostname of the system.

inbound-proxy proxy-host Inbound proxy hostname if the incoming connection from the Data Domain system is through a proxy.

inbound-proxy-port proxy-port Inbound proxy port number if the incoming connection from the Data Domain system is through a proxy.

outbound-proxy proxy-host Outbound proxy hostname if the connection from the DD Management Center to the Data Domain system is through a proxy.

outbound-proxy-port proxy-port Outbound proxy port number if the connection from the DD Management Center to the Data Domain system is through a proxy.

Note

The proxy options are equivalent to the firewall options in the graphical user interface.

Example # managed-system add host1234.mycompany.com The SHA1 fingerprint for the remote host's CA certificate is XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX Do you want to trust this certificate? Are you sure? (yes|no) [no]: yes ** Once added, all "admin" role users on this management center will operate on "host1234.mycompany.com" system with "admin" role.
