Table: CVMVolDg agent entry points

Entry Point

Description

Online

Imports the shared disk group from the CVM master node, if the disk group is not already imported.

Starts all volumes and volume sets in the shared disk group specified by the CVMVolume attribute.

Sets the disk group activation mode to shared-write if the value of the CVMActivation attribute is sw. You can set the activation mode on both slave and master systems.

Offline

Removes the temporary files created by the online entry point.

If the CVMDeportOnOffline attribute is set to 1 and if the shared disk group does not contain open volumes on any node in the cluster, the disk group is deported from the CVM master node.

Monitor

Determines whether the disk group, the volumes, and the volume sets are online.

The agent takes a volume set offline if the file system metadata volume of a volume set is discovered to be offline in a monitor cycle.

Note:

If the CFSMount resource goes offline and the file system on the volume set is unmounted, the agent retains the online state of the volume set even if the file system metadata volume in the volume set is offline. This is because the CVMVolDg agent is unable to determine whether or not the volumes that are offline are metadata volumes.

Clean

Removes the temporary files created by the online entry point.
