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” on page 108 for
more information.)
To perform a Rebuild operation:
1. Select the DDD device on the Main screen of the
Administration and Monitoring Program.
2. Select Rebuild Device.
3. Select a RDY drive to use to reconstruct the data, or
click on OK to use the same drive slot and SCSI ID if
you have physically replaced the defunct drive.
4. The reconstruction begins automatically and reports
progress information on the screen.
Notes
1. The ServeRAID adapter or controller can perform
only one Rebuild operation at a time.
2. If the array contains a critical (CRT) logical drive,
the Rebuild operation changes the hard disk
drive state from DDD to RBL. After the Rebuild
operation completes, the hard disk drive state
changes from RBL to ONL. (If you rebuild to a
RDY drive, the DDD drive is removed from the
disk array and becomes a defunct hot-spare
(DHS).)
3. The hard disk drive being rebuilt must be the
same size or larger than the failed drive.
4. If a hot-spare (HSP) drive is available, a Rebuild
operation will start automatically.
5. If multiple hot-spare (HSP) drives are available,
the ServeRAID adapter or controller searches all
the drives on each channel for a hot-spare drive
of the appropriate size. The first appropriate
hot-spare drive found enters the Rebuild (RBL)
state.
Adapter administration:
This section provides instructions for copying the drive
configuration to the ServeRAID adapter or controller,
copying the ServeRAID adapter or controller configuration
to the drives, initializing the adapter or controller
configuration, and scanning for new drives.
Copying the drive configuration to the adapter:
