Replacing and rebuilding a drive

When a hard disk drive goes defunct, a Rebuild operation is required to reconstruct the data for the device in its respective disk array. The ServeRAID controllers can reconstruct RAID level-1 and RAID level-5 logical drives, but they cannot reconstruct data stored in RAID level-0 logical drives. To prevent data integrity problems, the ServeRAID controllers set the RAID level-0 logical drives to blocked during a Rebuild operation. After the Rebuild operation completes, you can unblock the RAID level-0 logical drives, and access them once again. But remember, the logical drive might contain damaged data.

To perform a Rebuild operation:

  1. Select the defunct physical drive Defunct physical drive from the Main Tree.
  2. Select Replace drive and rebuild from the Actions menu.
  3. Click OK to use the same drive slot and SCSI ID if you have physically replaced the defunct drive with a new drive.

Once you have replaced the defunct drive with a new drive, the ServeRAID Manager automatically starts rebuilding the drive. The Manager displays a progress indicator in the status bar.

Use this action on defunct drives that are part of a critical logical drive. If the defunct drive is not part of any critical logical drives, but is in the array, you cannot use this action. Use Set drive state to online instead.
