You can manage drives to locate all of the drives that comprise a selected pool, volume group or SSD
Cache, remove capacity from a pool or SSD Cache, enable security, assign hot spares, and replace a drive.
Turn on locator lights in a pool, volume group, or SSD Cache
You can locate drives to physically identify all of the drives that comprise a selected pool, volume group, or SSD Cache. An LED indicator lights up on each drive in the selected pool, volume group, or SSD Cache.
Remove capacity from a pool or SSD Cache
You can remove drives to decrease the capacity of an existing pool or SSD Cache. After you remove drives, the data in each volume of the pool or SSD Cache is redistributed to the remaining drives. The removed drives become unassigned and their capacity becomes part of the total free capacity of the storage array.
Enable security for a pool or volume group
You can enable Drive Security for a pool or volume group to prevent unauthorized access to the data on the drives contained in the pool or volume group. Read and write access for the drives is only available through a controller that is configured with a security key.
Assign hot spares
You can assign a hot spare as a standby drive for additional data protection in RAID 1, RAID 5, or RAID 6 volume groups. If a drive fails in one of these volume groups, the controller reconstructs data from the failed drive to the hot spare.
Replace drive logically If a drive fails or you want to replace it for any other reason, and you have an unassigned drive in your storage array, you can logically replace the failed drive with the unassigned drive. If you do not have an unassigned drive, you can physically replace the drive instead.
