Veritas Volume Replicator (VVR) enables you to replicate data volumes on a shared disk group in Storage Foundation. In this environment, a two-node cluster on the primary site exists with a shared disk group. A two-node or single-node cluster exists on the secondary site; the disk group does not need be a shared disk group.
The VVR feature is provided with Storage Foundation. For configuring instructions for VVR:
See Configuring global clustering.
For complete details of VVR in a shared disk environment:
See the Veritas Volume Replicator Administrator's Guide.
