Resource ownership must be set up correctly to avoid problems when configuring Enterprise Vault in a cluster. The Configuration wizard only lists a resource group for selection if every resource in the group has the node on which you are running the wizard listed as a possible owner.
Resource ownership and resource dependencies must also be set up correctly to ensure failovers work as planned.
The Enterprise Vault Configuration wizard sets up the dependencies for the Enterprise Vault service resources and the Server Instance resource when it adds them to the resource group.
If you add a shared disk to an existing cluster you must ensure you set up the disk resource and dependencies correctly.
