Replicated Data Set defined

Veritas Volume Replicator (VVR) replicates data from a Primary host, where the application is running, to one or more Secondary hosts. A Replicated Volume Group (RVG) on the Primary host and its counterparts on the Secondary hosts make up a Replicated Data Set (RDS). An RDS is not a Veritas Volume Manager object; it is a concept used in VVR. An RDS enables grouping of the RVG on the Primary host and its counterparts on the Secondary host.

VVR VEA operates on an RDS, that is, the Primary RVG and all the Secondary RVGs in the RDS. Using VVR VEA, you can perform tasks from any host in an RDS; VVR performs the same tasks on the required hosts in the RDS if appropriate.
