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.

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. The drive's capacity is subtracted from the Unconfigured Capacity node in the Logical View.

Unassigning a 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. The drive's capacity is added to the Unconfigured Capacity node in the Logical View.
