Veritas Volume Replicator (VVR) technology is a license-enabled feature of Veritas Volume Manager (VxVM), so you can convert VxVM-managed volumes into replicated volumes managed using VVR. In this example, the process involves grouping the Oracle data volumes into a Replicated Volume Group (RVG), and creating the VVR Secondary on hosts in another VCS cluster, located in your DR site.

When setting up VVR, it is a best practice to use the same DiskGroup and RVG name on both sites. If the volume names are the same on both zones, the Mount resources will mount the same block devices, and the same Oracle instance will start on the secondary in case of a failover.
