Assigning a Hot Spare
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 unassigned drives as hot spare drives.
Procedure
To assign a hot spare drive, select one or more drives in the Physical View from the available unassigned drives; then, select either the Drive >> Assign Hot Spare pull-down menu option, or Assign Hot Spare from the right-mouse pop-up menu.
Result: The drive changes from unassigned to standby hot spare. The drive's capacity is subtracted from the Unconfigured Capacity node in the Logical View.
De-assigning a Hot Spare
Use this option to return a selected hot spare drive or drives to an unassigned state.
Caution:
Procedure
To de-assign a hot spare drive, select one or more standby hot spare drives in the Physical View; then, select either the Drive >> De-assign Hot Spare pull-down menu option, or De-assign Hot Spare from the right-mouse pop-up menu.
Result: The drive changes from standby hot spare to unassigned. The drive's capacity is added to the Unconfigured Capacity node in the Logical View.
