Prerequisites

  Make sure that the volumes that are a part of the RVG are present on the shared storage.

  Make sure the disk group can be deported and imported on all the nodes in the cluster.

  VVR must use a virtual IP address for replication.

  All the nodes in the VVR cluster environment must use the same port number for replication. You can verify this by using the vrport command.

For more information on displaying and changing the port numbers, see section "Displaying and Changing the Ports Used by VVR" in the VERITAS Volume Replicator Administrator's Guide.
