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: SCSI only—In a RAIDstation storage cabinet, drives

have hot swap (SCA-2) connectors so that failed drives can

be removed or replaced without software intervention. The

RAIDstation subsystem detects that a failed drive has been

physically replaced and the controller automatically starts a

rebuild operation.
