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 problem.
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
recommend because the data on the remaining disk will be lost when the hard
drive is used to create another RAID 1 array.
