This chapter explains how to use Veritas Volume Replicator (VVR) for off-host processing on the Secondary host. You can use the In-Band Control (IBC) Messaging feature with the FastResync (FMR) feature of Veritas Volume Manager (VxVM) and its integration with VVR to take application-consistent snapshots at the replicated volume group (RVG) level. This lets you perform off-host processing on the Secondary host.

This chapter also explains how to perform off-host processing operations using the vradmin ibc and vxibc commands.
