Chapter 5: VIA VT8237 SATA RAID Setup Guide
Rebuild Broken RAID 1 Array
When booting up the system, BIOS will detect if any member disk drives of
RAID has failed or is absent. If BIOS detects any disk drive failures or missing
disk drives, the status of the array will be marked as broken.
If BIOS detects a broken RAID 1 array but there is a spare hard drive available
for rebuilding the broken array, the spare hard drive will automatically become
the mirroring drive. BIOS will show a main interface just like a duplicated
RAID 1. Selecting Continue to boot enables the user to duplicate the array
after booting into operating system.
If BIOS detects a broken RAID 1 array but there is no spare hard drive available
for rebuilding the array, BIOS will provide several operations to solve such
1. Power off and Check the Failed Drive:
This item turns off the computer and replaces the failed hard drive with a good
one. If your computer does not support APM, you must turn off your
computer manually. After replacing the hard drive, boot into BIOS and select
Choose replacement drive and rebuild to rebuild the broken array.
2. Destroy the Mirroring Relationship:
This item cancels the data mirroring relationship of the broken array. For broken
RAID 1 arrays, the data on the surviving disk will remain after the destroy
operation. However, Destroy the Mirroring Relationship is not recom-
mended because the data on the remaining disk will be lost when the hard drive is
used to create another RAID 1 array.
