About the CVMVolDg agent

The CVMVolDg agent represents and controls CVM disk groups and CVM volumes within the disk groups. The global nature of CVM disk groups and volumes requires importing them only once on the CVM master node.

Configure the CVMVolDg agent for each disk group used by an Oracle service group. Configure a disk group for only a single Oracle service group. If the database uses cluster file systems, configure the CFSMount agent for each volume in the disk group.
