Volume Manager Diskgroup (VMDg) agent
The Volume Manager Diskgroup agent imports, monitors, and deports a cluster disk group configured using Storage Foundation. The agent makes the disk group highly available. The Volume Manager Diskgroup agent supports Dynamic Multi-Pathing (DMP) and works in a SAN environment. The agent is represented by the VMDg resource type.
This agent supports intelligent resource monitoring and uses Intelligent Monitoring Framework (IMF) for resource state change notifications. The agent relies on the disk group related PnP notifications raised by Storage Foundation (SFW). For example, SFW raises PnP notifications for disk group import and deport state change and for disk group access state change (read-only, read/write).
For more information about IMF, refer to the Cluster Server Administrator's Guide.
Note:
Use this agent to manage volumes on disk groups configured using Storage Foundation. Do not use this agent if you use other software to manage shared storage.
