The CP server service group (CPSSG) is a VCS service group. An I/O fencing configuration using CP server requires the CP server service group.

You can configure the CP server service group failover policies using the Quorum agent. CP server uses the Quorum agent to monitor the virtual IP addresses of the CP server.

See About the Quorum agent for CP server.
