Multiple Failures in the Same Array
Except in RAID 6 and RAID 60 arrays (see
), if more than one
disk drive fails at the same time in the same array, the data can’t be
recovered.
Correct the cause of the failure or replace the failed disk drives. Then,
restore your data (if available).
Note:
In some instances, RAID 10 and RAID 50 arrays may survive
multiple disk drive failures, depending on which disk drives fail. For
more information, refer to the Adaptec Storage Manager User’s Guide or
online Help.
Resetting the Controller
This section explains how to reset (or flash) your Adaptec RAID
controller. You may want to do this if the controller becomes
inoperable, or if a firmware upgrade is unsuccessful.
To reset your Adaptec RAID controller:
1
Download the firmware version currently installed on your
controller from
www.adaptec.com
.
2
Extract the downloaded files to a folder on your local hard drive (for
example,
C:\Download\Drivers
).
3
Create a bootable MS–DOS floppy disk and copy the
AFU.exe
file to
it. Copy the first firmware image to the same floppy disk.
4
Create additional bootable MS–DOS floppy disks and copy each
additional firmware image to its own floppy disk.
5
Power off your computer, disconnect the power cord, then open the
cabinet following the manufacturer’s instructions.
6
Disconnect all cables from the controller, then attach a shorting
jumper to the Mode 0 flash connector. (To locate the Mode 0 flash
connector on your Adaptec RAID controller, see the figures in
Your RAID Controller on page 18
7
Reconnect the power cord, power on your computer, then boot to
the floppy disk containing the
IFU.exe
