Physical Device Administration
Use the following information to set device states and rebuild devices.
Setting Physical Device States: The following table
shows the valid device states and valid alternative states.
Device Alternative States

To set or change the physical device state:
NOTE: If you set a DDD drive to ONL without performing a Rebuild (RBL) operation and that drive is part of a critical (CRT) logical drive, your system might lose data.
Rebuilding a Device: 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.)
To perform a Rebuild operation:
