Certain practices should be followed when you create a Bunker RVG.
Best practices for creating a Bunker RVG are as follows:
The Bunker RVG must contain only the Replicator Log and no data volumes.
The Bunker Replicator Log must be of the same size and the same name as the Primary Replicator Log. Adding the Bunker to the RDS fails if the Bunker Replicator Log is not of the same size as the Primary Replicator Log. In the case of a storage Bunker, the Replicator Log name may be different.
Veritas recommends that you do not replicate to the Bunker using asynchronous mode as the Bunker node may not be up-to-date at all times. By default, replication to the Bunker node is in the synchronous override mode.
