CBR2107I Drive drive-name VARY OFFLINE failed.
Explanation
The operator has entered a command of the form:
VARY SMS,DRIVE(drive-name)OFFLINE
The attempt to VARY the specified drive drive-name offline has failed, for the reason noted in a previous message to the operator. The most likely reason for the failure is the inability to demount the volume which is currently mounted on the drive.
System action
The drive is left in the pending offline state; this means that no new work will be scheduled to the drive. If there is a volume which cannot be demounted, that volume is unavailable until the situation is corrected.
Operator response
Notify the service representative.
