Viewing information about the Secondary RVG
Prev	Interpreting the information in the Volume Replicator views	Next

To view information about the Secondary RVG, from the tree view in the left pane, expand the Replication Network node to view the RDSs on that host. Expand the required RDS node to select the appropriate Secondary RVG from the tree view of the left pane.

The right pane displays information about the Secondary RVG. The Secondary RVG view is similar to the Primary RVG view, except that it displays some additional information.

Figure showing Secondary RVG properties in the VEA console

Clicking the Secondary RVG tab in the right pane displays the following information in the upper part of the VEA window.

The following table describes the Secondary RVG fields.

Table: Secondary RVG information

Displayed Field	Description
Primary RVG	Displays the name of the Primary RVG.
Secondary Host	Displays the host name or IP address of the Secondary that is used for replication.
Dynamic Disk group	Displays the name of the dynamic disk group, whose volumes are a part of the RVG. If the RVG is part of a clustered disk group, then the disk group name is displayed with a Cluster tag against it.
Data Volumes	Displays the information about the number of data volumes that are associated with the Secondary RVG.
RVG State	Displays the state of the RVG.
Replicator Log Size	Displays the size of the Replicator Log.
Replication Mode	Displays the current mode of replication. The different modes are, synchronous, asynchronous, and synchronous override.
Replication Status	Displays the current status of replication.
Replicator Log Protection	Displays the value that has been set for Replicator Log protection, that is, Autodcm, DCM, Off, Fail, or Override.
Latency Protection	Displays the value that has been set for Latency protection, that is, OFF, FAIL, Override.
Protocol	Displays the protocol that Volume Replicator uses for sending data from Primary to Secondary during replication. UDP/IP is the default replication protocol. However, you can use either UDP/IP or TCP/IP. Displays STORAGE in the case of a Bunker Secondary where the storage on the Bunker Secondary is directly accessible from the Primary and STORAGE protocol has been used.
Packet Size (Bytes)	Displays the size of the packet that is used to send the data to Secondary when the UDP protocol is used.
Bandwidth (Mbps)	Displays the bandwidth that Volume Replicator uses. The default unit is Megabits per second (Mbps) and the minimum allowed value is 1 Mbps. If no value has been specified Volume Replicator uses the available bandwidth by default. In this case this field displays the Maximum Available value.
Compression	Specifies whether compression is enabled or disabled.
Replication Time Lag	Displays the exact number of hours, minutes, and seconds by which the Secondary is behind the Primary. The current time on the Primary is also displayed. Note that this field is displayed when the Primary becomes unavailable. This information helps you to decide which Secondary should take over the Primary role in a setup with multiple Secondaries, when a disaster occurs.

After this, the Secondary RVG view displays information about the RLINKs that are configured for the selected Primary RVG. This is similar to the Primary RLINK information.

The following table describes the fields that display the Secondary RVG data volume information.

Table: Secondary RVG data volume information

Displayed Field	Description
Data Volumes	Displays the names of the data volumes that are associated with the RVG.
Size	Displays the size of the data volumes.
Layout	Displays the type of volume layout, that is: Concatenated Mirrored Concatenated Striped Mirrored Striped Mixed For more information about the volume layout, see Storage Foundation Administrator's Guide.
DCMLog	Displays whether the DCM log is present. Valid values are: Yes Indicates that the volume has a DCM log. No Indicates that the volume does not have a DCM log.
Primary Volume	Displays the name of the corresponding Primary data volume.
