Since Enterprise Vault requires the SQL database, if you cluster SQL Server using Symantec Cluster Server, Symantec recommends setting a service group dependency between the EV service group and the SQL service group.

In the disaster recovery environment with Volume Replicator replication, the EV Replicated Volume Group (RVG) should be linked as a parent to the SQL Server service group as a child. Set the same service group dependencies on the primary and secondary site clusters.

For the Volume Replicator environment, the DR wizard can configure DR only for a service group that has no child. Therefore, set service group dependencies only after running the DR wizard.

For more information on setting service group dependencies, see the Symantec Cluster Server Administrator's Guide.
