About hybrid service groups

A hybrid service group is for replicated data clusters and is a combination of the failover and parallel service groups. It behaves as a failover group within a system zone and a parallel group across system zones.

A hybrid service group cannot fail over across system zones. VCS allows a switch operation on a hybrid group only if both systems are within the same system zone. If no systems exist within a zone for failover, VCS calls the nofailover trigger on the lowest numbered node. Hybrid service groups adhere to the same rules governing group dependencies as do parallel groups.

See About the nofailover event trigger.
