Bunker RVG

An RVG on the Bunker node that contains only a Replicator Log but no data volumes and has RLINKs to the Primary and Secondary. Under normal operating conditions this RVG will function as a Secondary. In the case of a disaster at the Primary, the Bunker RVG can act as a Primary and can be used to replay the pending writes from the Replicator Log on the Bunker node to the Secondary and thus bring the Secondary up-to-date with the original Primary.
