VCS agents for VVR 

You can use the following VCS agents for VVR in a VCS global cluster setup: 

• RVG agent

  The RVG agent manages the Replicated Volume Group (RVG). Specifically, it brings the RVG online, monitors read-write access to the RVG, and takes the RVG offline. Use this agent when using VVR for replication.

• RVGPrimary agent

  The RVGPrimary agent attempts to migrate or take over a Secondary to a Primary following an application failover. The agent has no actions associated with the offline and monitor routines.

• RVGSnapshot agent

  The RVGSnapshot agent, used in fire drill service groups, takes space-optimized snapshots so that applications can be mounted at secondary sites during a fire drill operation.

See the Veritas Cluster Server Agents for Veritas Volume Replicator Configuration Guide for more information. 

VCS agents for third-party replication technologies 

VCS provides agents for other third-party array-based or application-based replication solutions. These agents are available in the Veritas High Availability Agent Pack software. 

See the Veritas High Availability Agent Pack Getting Started Guide for a list of replication technologies that VCS supports.
