Rebuilding a Degraded Array
When a drive in an array fails, and that drive is not protected by an
automatic hot spare, the array can be restored to Optimal status.
Note: You can select Rebuild even if the failed drive has not
been replaced and try using the drive again. If the rebuild
attempt is not successful, replace the drive before starting
another rebuild.
To rebuild an array, follow these steps:
1 Replace the failed drive according to the procedure in your
hardware documentation.
2 After the failed drive has been replaced, select
Logical Configuration View in Storage Manager.
3 Double-click the array group icon to open the Array Group
Information window.
4 Click Rebuild in the Array Group Information window to start
the rebuild process.
The drive displays a white flag to indicate that a rebuild operation
is in process. The array and LSU icons display yellow flags. The
percentage completion of the rebuild operation is displayed in the
Array Group Information window. When the rebuild is
successfully completed, the flags disappear and the array status
returns to Optimal.
Note: In a supported SAF-TE or SES enabled storage
enclosure, drives have hot swap (SCA-2) connectors so that
failed drives can be removed or replaced without software
intervention. The enclosure detects that a failed drive has
been physically replaced and the controller automatically
starts a rebuild operation.
Assigning Hot Spares
To assign a drive as a hot spare, click Make Hotspare in the drive’s
Device Information window. Click Remove Hotspare to reassign
an existing hot spare drive as a normal drive.
