The VvrRvg agent represents the RVG and enables failover of the RVG between nodes in a cluster, thus making it highly available. The VvrRvg agent is installed and configured separately on the Primary and Secondary cluster. The agent enables replication between clusters by managing the Volume Replicator Primary node in one cluster and the Volume Replicator Secondary node in another cluster, each of which can be failed over in its respective cluster. In this way, the replication role between the Primary and Secondary is made highly available.

If your configuration uses a storage Bunker, then the action that the VvrRvg agent takes during failover depends on the replication status. If a storage Bunker is initially associated with SYS1 of the Primary cluster, then whenever the replication service group fails over to the other node SYS2 in the cluster, the storage Bunker disk group is also moved to the other node.

The following table provides some conditions that govern the failover to the other node.
