Viewing Replication Information

You can get information about the VVR environment using the various views presented by VVR VEA. VVR VEA provides a tree view, which is a hierarchical top-level view for each VVR object. The tree view enables you to drill down to get detailed information for each VVR object. For each VVR object in the tree view, VVR VEA provides an associated view that consists of tabbed views containing related information about the selected node. You can display the VVR VEA views on any host in an RDS.

Viewing the RDSs Present on the Selected Host

When you click the Replicated Data Sets node in the tree view, the RDSs that are configured on the selected hosts are displayed in the tree view; the right pane displays the RDS List View, which consists of the Summary tab and the Configuration Errors tab.

  The Summary tab displays information about the RDSs present on the selected host, such as the number of RDSs of which the selected host is a part, name of the RDS, name of the Primary, Primary RVG state, number of Secondaries in the RDS, and the replication status of the RDS.

  To view configuration errors, if any, in the RDS use the Configuration Errors tab. Each configuration error in an RDS is displayed on a separate line. If multiple configuration errors exist in an RDS, the view displays multiple lines for that RDS.

  The Configuration Errors view is persistent across all the views in VVR VEA and displays configuration errors related to the object selected in the tree view. When the node selected in the tree view is the Replicated Data Sets node, the Configuration Errors view displays configuration errors for all the RDSs. Similarly, if the node selected in the tree view is an RDS, the Configuration Errors view displays errors related to that particular RDS only.

Using the RDS List View

• To display the RDS List View from any other view, click the Replicated Data Sets node in the tree view. You can go to the RDS View from the RDS List View, by double-clicking the RDS name or by clicking the RDS node in the tree view.

Information Displayed in the Summary View of the RDS List View

RDS Count	Displays the number of RDSs on the selected host.
RDS Name	Displays the name of the RDS and the RDS icon.
Primary	Displays the name of the Primary host.
Primary RVG State	Displays the state of the Primary RVG.
Secondaries	Displays the number of Secondary hosts in the RDS.
Replication Status	Displays the status of replication between the Primary and the Secondaries in the RDS.

Viewing RDS Information

The RDS view displays detailed information about the selected Replicated Data Set (RDS).

Using the RDS View

Use the RDS view to get detailed information about a selected Replicated Data Set (RDS). To display the RDS view, expand the Replicated Data Sets node and select the RDS name in the tree view. For example, expand the Replicated Data Sets node in the tree view, and then click the RDS name hr_rvg to display the RDS view for hr_rvg.

By default, the Summary tab displays information about the selected RDS. Select the Configuration Errors tab in the RDS view to check whether configuration errors exist for the selected RDS.

Information Displayed in the RDS View

The Summary tab in the RDS view displays the following high-level information about the Primary RVG in its top region:

Primary Replicated Volume Group:
Host	The name of the host on which the Primary RVG is present and the version of the operating system on the host.
Disk Group	The name of the disk group.
RVG State	State of the RVG, whether enabled or disabled for I/O.
Replicated Volume Count	Number of data volumes in the RVG.
Replicated Data Size	The sum of the sizes of each data volume in the RVG.
Checkpoints	Number of checkpoints.
RVG Version	The version of the RVG.

• The table in the lower region of the RDS View (Summary tab) displays the following details for each Secondary in the selected RDS:

Secondary	Name of the Secondary host.
Data Status	Status of replication on the Secondary. For example, consistent, up-to-date. For more information about the values of the data status, refer to Displaying Consolidated Replication Status.
Replication Status	Status of replication on the Secondary. For example, replicating (connected).
Current Mode	Displays the mode of replication, that is, synchronous or asynchronous.
Logging To	Indicates whether writes are being logged to the DCM or SRL.
Bytes in Log	The number of bytes in the SRL or DCM.
Updates Behind	Indicates the extent to which the Secondary is behind the Primary.

Viewing Information About RVGs

When you double-click the RDS name or click the plus sign next to the RDS name in the tree view, the names of the Primary host and Secondary hosts in the RDS are displayed in the tree view. VVR VEA displays the names of the Primary and Secondary hosts and not the names of the Primary and Secondary RVG because the names of the Primary and Secondary RVG are the same on all the hosts in the RDS. Also, the name of the RDS will be the same as the name of the Primary or Secondary RVG.

Use the RVG View to get information about a specific Replicated Volume Group (RVG). For example, if you click the Primary name seattle under the RDS hr_rvg in the tree view, the RVG view for the Primary seattle is displayed. The RVG view displays detailed information about the selected RVG.

Using the RVG Views

  To display the RVG view, do one of the following:

  Expand the RDS name node, and then select the Primary or Secondary host name in the tree view.

  In the tree view, double-click the RDS name, and then select the Primary or Secondary host name.

Viewing Information About the Primary RVG

  To display the Primary RVG view, do one of the following:

  Expand the RDS name node, and select the Primary host name in the tree view.

  In the tree view, double-click the RDS name and select Primary host name.

The Primary RVG view is displayed. For a description of the information displayed in the Primary RVG View, see Information displayed in the Primary RVG View and the Secondary RVG View.

Viewing Information About the Secondary RVG

  To display the Secondary RVG view, do one of the following:

  Expand the RDS name node, and select the Secondary host name in the tree view.

  In the tree view, double-click the RDS name and select Secondary host name.

The Secondary RVG view is identical to the Primary RVG view, except that the Secondary RVG view does not contain the Checkpoints tab in the top region and the Secondary column in the lower region. The Secondary RVG view displays the same information as the Primary RVG view. See Information displayed in the Primary RVG View and the Secondary RVG View.

Secondary RVG View

Information displayed in the Primary RVG View and the Secondary RVG View

The layout for RVG views is as follows.

• The upper region contains tabs in which related information about the selected RVG is displayed. The Summary tab displays information that is identical to that of the RDS view. For details, see Information Displayed in the RDS View.
• The table in the lower region of RVG View displays the attributes of replication to the remote hosts.

The information about the selected RVG that is displayed in the various tabs is as follows:

Summary tab	Displays the following information about the RVG: Host: Name of the host of the RVG. In the Primary RVG View, host name is the name of the Primary host.

Replicated Volume Count: Number of data volumes in the RVG Replicated Data Size: The sum of the sizes of the data volumes in the RVG. Checkpoint: Number of checkpoints. Version: RVG version. Note that the type of the view, Primary RVG view or Secondary RVG view, and the RVG name is displayed at the top of the view.
