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.

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	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. In the Secondary RVG View, the host name is name of the Secondary host.  Disk Group: Name of the disk group. In a shared environment, indicates that the disk group is shared.  Replicated Volume Count: Number of data volumes in the RVG. This information is not applicable for bunker RVG.  Replicated Data Size: The sum of the sizes of the data volumes in the RVG. This information is not applicable for bunker RVG.  Checkpoint: Number of checkpoints. This information is not applicable for bunker RVG.  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.
  Data Volumes	Displays information about the data volumes associated with the selected Primary or Secondary RVG. Information includes:  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.  Volume Name: Name of the volume  Size: Size of the volume  Layout: Layout of the volume  Mirrors: Number of mirrors.  DCM: Indicates whether or not the volume has a Data Change Map (DCM) associated with it.   For a bunker Secondary, data volumes do not exist, and therefore the Data Volume tab does not display.
  SRL	Displays the following information about the SRL:   Name: Name of the SRL  Size: Size of the SRL  Layout: Layout of the SRL  Mirrors: Number of mirrors
  Checkpoints	In the Primary RVG view, the checkpoints are listed. If checkpoints do not exist, VVR VEA indicates that checkpoints are not found. In the Secondary RVG view and the bunker RVG view, the Checkpoints tab does not display. To get the latest checkpoints, click Get Checkpoints.
  Cluster Information  This tab appears only if the selected RVG has a disk group that is shared.	The following information is displayed if the disk group is shared:  Cluster Name: Name of the cluster.  Cluster Master: Name of the master node in the cluster.  Logowner: Name of the logowner of the selected RVG.  Cluster Members: Names of the nodes in the Primary cluster or the Secondary cluster.
  Configuration Errors	Display problems with the configuration, if any.

The table in the lower region of the Summary tab in the RVG Views displays the replication attributes to the remote host.

Secondary	In the Primary RVG view, the name or names of the Secondary hosts are displayed. If a bunker exists in the RDS, then the name of the bunker host is displayed.  In the Secondary RVG view, this column is not displayed.
RVG Role	Role of the host, that is, Primary, Secondary or Bunker.
Replication IP	The host name and IP address used for replication.
Replication Mode	Displays the mode of replication, that is, synchronous or asynchronous.
SRL Protection	Displays autodcm, dcm, override, or off depending on the chosen option.
Latency Protection	Displays override, or off depending on the chosen option.
Latency-Low Mark	Number of updates in the SRL before the latency protection becomes inactive and updates succeed.
Latency-High Mark	Specifies the maximum number of waiting updates in the SRL before the latency protection becomes active and updates stall or fail.
Protocol	Transport Protocol being used for replication.
Bandwidth Limit	Displays the bandwidth limit that has been set for VVR. Displays none if a bandwidth limit has not been set, that is, Bandwidth Throttling is disabled.
