About resource groups and Enterprise Vault service resources in a Microsoft cluster

Before configuring an Enterprise Vault server as a server with cluster support, you must create a cluster resource group, which will become the Enterprise Vault virtual server. The Enterprise Vault Configuration wizard adds the following Enterprise Vault service resources to the resource group, to control and monitor the equivalent Enterprise Vault services on the active node:

The Configuration wizard also adds one more resource to the group: an Enterprise Vault Server Instance resource. All the other Enterprise Vault resources in the group are configured to be dependent on this resource, directly or indirectly. Its purpose is to prevent failovers to nodes already running Enterprise Vault, avoiding an active/active operation mode.
