Rebuilding a Defunct Drive

Rebuilding a Defunct Drive

When a hard disk drive goes defunct (DDD), a Rebuild operation is required to reconstruct the data for the device in its respective disk array.
The ServeRAID adapters and 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 adapters and 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.
(Refer to 'Unblocking Logical Drives' for more information.)

Before you rebuild a drive, review the following guidelines and general information.
