Rebuilding Failed Disk Drives - LSI SCSI 320-0 Configuration

Rebuilding Failed Disk Drives

If a disk drive fails in an array configured as a RAID 1, 3, or 5 logical drive, you
can recover the lost data by rebuilding the drive. If a rebuilding spare fails, a
new rebuild is started using a second spare, if available. The capacity of the
second spare must be equal to or greater than the failed drive.
Rebuild Types The rebuild types are:
Type
Automatic If you have configured hot spares, MegaRAID automatically tries to use them to
Rebuild rebuild failed disks. 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 Manual rebuild is necessary if no hot spares with enough capacity to rebuild the
Rebuild failed drives are available. Select the MegaRAID Manager main menu Rebuild
option or the Rebuild option on the Objects/Physical Drive menu.
