4.9 Rebuilding Logical Drives

Depending on whether or not there is a spare drive, rebuilding is initiated automatically or must be started manually. In the presence of a spare drive, the system automatically rebuilds onto the spare drive. This process is done in the background, thus it is transparent to users.

In the absence of a spare drive, rebuilding must be initiated manually. Before initiating a manual rebuild, you must first replace the failed drive. If you install the replacement drive on the same connector (that is, the same channel and SCSI ID), then you can proceed with the rebuilding process; otherwise, you need to scan in the drive first.

To rebuild a logical drive

1. Display the Logical Drives window by clicking on the Logical View command button in the introduction or selecting Logical View from the RAID View navigation panel.

2. In the Logical Drives window, click on the degraded logical drive.

3. Choose the Operation tab and then the Rebuild sub-tab.

4. Choose a logical drive to rebuild. Logical drives in need of rebuilding will be marked "degraded" and will have darkened icons. Click OK. You will be prompted for a password. Enter it and click OK.

5. The Rebuild in Progress window will appear and show the percentage of rebuild progress until complete.

6. Once the logical drive has been rebuilt, the logical drive icon will return to its normal color and the Rebuild tab will no longer be available under Operation.
