Drive Replacement (Rebuilding a Defunct Drive)
Drive Replacement (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.
Before you rebuild a drive, review the following
guidelines
