The Monitor entry point of the disk group agent returns ONLINE even if the disk group is disabled

This is expected agent behavior. VCS assumes that data is being read from or written to the volumes and does not declare the resource as offline. This prevents potential data corruption that could be caused by the disk group being imported on two hosts.

You can deport a disabled disk group when all I/O operations are completed or when all volumes are closed. You can then reimport the disk group to the same system. Reimporting a disabled disk group may require a system reboot.


A disk group is disabled if data including the kernel log, configuration copies, or headers in the private region of a significant number of disks is invalid or inaccessible. Volumes can perform read-write operations if no changes are required to the private regions of the disks.
