Veritas Volume Replicator (VVR) replicates data written to shared volumes from the primary site to the disaster recovery site. Likewise, Veritas File Replicator (VFR) replicates shared file systems. Configure VCS Global Cluster Option (GCO) to enable failover from primary to the disaster recovery (DR) site. When the primary site goes down or the network link fails, VCS Global Cluster Option (GCO) coordinates the failover of applications to the disaster recovery site.

The VVR agent automatically fails over the applications writing to the volume block devices. However, for file systems, you need to manually fail over the application writing to the file system to the DR site.

For more information on configuring VVR, VFR and VCS GCO, refer to the Veritas InfoScale™ Solutions Replication Administrator's Guide.
