CVMCluster agent

The CVMCluster agent controls node membership on the cluster port associated with CVM. The CVMCluster resource requires the CVMVxconfigd resource and must be configured to depend on CVMVxconfigd. The CVMCluster agent executable is /opt/VRTSvcs/bin/CVMCluster/CVMClusterAgent. The type definition is in the /etc/VRTSvcs/conf/config/CVMTypes.cf file. The configuration is added to the main.cf file after running the cfscluster config command.
