Use this option to assign a selected unassigned drive as a hot spare drive. A hot spare drive contains no data and acts as a standby in case any drive fails in a RAID level 1, 3, or 5 array on the storage subsystem. The hot spare drive adds another level of redundancy to the storage subsystem.
Important: You can only assign Optimal as hot spare drives.
To assign a hot spare drive:
1 |
Select one or more drives from the Physical View from the available unassigned drives. |
2 |
Select either the Drive >> Hot Spare >> Assign pull-down menu option, or Hot Spare >> Assign from the right-mouse pop-up menu. Result: The drive changes from unassigned to standby hot spare. |
Use this option to return a selected hot spare drive or drives to an unassigned state.
Caution:
To unassign a hot spare drive:
1 |
Select one or more standby hot spare drives from the Physical View of the Subsystem Management Window. |
2 |
Select either the Drive >> Hot Spare >> Unassign pull-down menu option, or Hot Spare >> Unassign from the right-mouse pop-up menu. Result: The drive changes from standby hot spare to unassigned. |
