Brings the RVG online, monitors read and write access to the RVG, and takes the RVG offline. This is a failover resource. The RVG agent enables replication between clusters. It manages the Primary VVR node in one cluster and the Secondary VVR node in another cluster. Each node can be failed over in its respective cluster. In this way, replication is made highly available.
The RVG agent manages the state of the RVG during local failovers. The RVGPrimary agent manages the role of the RVG during a wide area failover.
Using a VCS global cluster enables you to fail over the Primary role from a Primary VVR node to a Secondary VVR node.
The RVG agent includes the following key features:
Removes potential single points of failure by enabling Primary and Secondary VVR nodes to be clustered.
Enables you to bring a service group online to start VCS-managed applications that use VVR.
Continues replication after a node in a cluster fails without losing updates.
Ensures that VVR can be added to any VCS cluster by including the RVG resource type definitions.
