Stopping of a RAID group disk drive is scheduled using the disk control command of the Storage Cruiser. This command returns control after the end of the stopping schedule of the disk drive.
Refer to "Command References" in the Storage Cruiser Operation Guide for information on the command.
Note
Depending on the status of the back up destination RAID group, a disk drive may not stop immediately.
While OPC physical copying
If the OPC physical copy is in progress on the disk drive, the disk drive stops after a certain period once the physical copy is completed.
While the disk is being accessed
If the RAID group for backup destination is being accessed, for example when backing up to a tape, the drive stops after a certain period once the access is stopped.
Other than the above, there are cases that the disk does not stop. Refer to "storageadm spindle (Disk Control Command)" in the Storage Cruiser Operation Guide for information on the command.
