Rebuilding Failed Disk Drives
If a disk drive fails in an array that is configured as a RAID 1 or 5 logical drive, you can
recover the lost data by rebuilding the drive.
Table 9.8 displays the rebuild types.
Table 9.8 Rebuild Types
Type Description
Automatic Rebuild If you have configured hot spares, MegaRAID
automatically tries to use them to rebuild failed
disks, as long as the failed drives are smaller
than or equal to the hot spares in size.
Display the Objects->Physical Drive screen
while a rebuild is in progress. The drive
indicator for the hot spare disk drive has
changed to REBLD A[array number]-[drive
number], indicating the disk drive being
replaced by the hot spare.
Manual Rebuild Manual rebuild is necessary if no hot spares with
enough capacity to rebuild the failed drives are
available. Select Rebuild on the Management
Menu or the Rebuild option on the Objects-
>Physical Drive menu.
Manual Rebuild - Rebuilding an Individual Drive

2. Choose Physical Drive from the Objects menu.
A device selection window displays the devices connected to the current controller.
3. Press the arrow keys to select the physical drive to be rebuilt and press <Enter>.
The physical drive action menu displays.
4. Select Rebuild from the action menu and respond to the confirmation prompt.
Rebuilding can take some time, depending on the drive capacity.
