Use the Associate Volume task to associate a volume to an Replicated Data Set (RDS) even when replication is in progress. This command associates a volume to all the RVGs of the RDS.
Ensure that volumes of the same name and same length exist on the Primary and all the Secondaries of the RDS. You must create volumes of the required layout on the Primary and the Secondary.
Caution Failure to meet the following prerequisites may result in the Secondary data volumes having unusable data.
Prerequisites for associating a volume to an RDS
Ensure that volumes of the same name and length as the Primary volumes exist on all the hosts in the RDS. If not, create them.
Verify that the volume to be added is inactive.
Synchronize the volume using the
syncvol command from the command-line interface (CLI).
Note By default, the Associate Volume task associates Data Change Maps (DCMs) to the volumes being added to the RDS, if DCMs have not been associated already. If any of the data volumes contains a DRL, this operation removes the DRL before associating the DCM to the volume.
