The volume set represents a logical grouping of volumes from the application perspective. In order for VVR to replicate the volume set successfully, the same volume configurations must exist on the Primary and the Secondary. Commands that break the configuration consistency will fail.
VVR tracks which component volumes make up the replicated volume set, and ensures that the component volumes of the volume set remain consistent between the Primary and the Secondary. If a component volume is added or deleted to the volume set, VVR makes the corresponding change to the RVGs on each host of the RDS. The component volumes with the same names and lengths must already exist on each host.
Adding a volume to a volume set that is associated to an RVG.
All the component volumes of the volume set are internally associated to the RVG.
If the volume set is already associated to the RDS, but some component volumes are excluded, use this command to add the component volume to the RDS.
This operation fails if the volume set is not associated to the RDS.
All the component volumes of the volume set are removed from the RVG. The membership of component volumes in the volume set is not affected.
Deleting a volume from a volume set that is associated to an RVG.
Deletes the volume from the RDS but the volume will still remain associated with the volume set.
Caution
Deleting a volume this way means that the volume set is only partially being replicated.
