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