The ClusterService group must be configured with the Application (for the wide-area connector), NIC, and IP resources. The service group may contain additional resources for Authentication Service or notification if these components are configured. The ClusterService group is configured automatically when VCS is installed or upgraded.

If you entered a license that includes VCS global cluster support during the VCS install or upgrade, the installer provides you an option to automatically configure a resource wac of type Application in the ClusterService group. The installer also configures the wide-area connector process.

You can run the Global Cluster Option (GCO) configuration wizard later to configure the WAC process and to update the ClusterService group with an Application resource for WAC.
