Multiple Failures in the Same Array
Except in RAID 6 and RAID 60 arrays (see
page 74
), 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
ICP Storage Manager
User’s Guide
or online Help.
Resetting the Controller
This section explains how to reset (or
flash
) your ICP RAID controller. You may want to do this
if the controller becomes inoperable, or if a firmware upgrade is unsuccessful.
To reset your ICP RAID controller:
1
Download the firmware version currently installed on your controller from
www.icp-
vortex.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 IFU.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 ICP RAID controller, see
the figures in
About Your RAID Controller
on page 15
.)
7
Reconnect the power cord, power on your computer, then boot to the floppy disk
containing the IFU.exe file (see
Step 3
).
8
At the prompt, type
a: \ifu update /c x
where
x
is the controller number.
9
Insert the other floppy disks when prompted.
10
When the flash is complete, power off your computer, disconnect the power cord, then
remove the jumper.
11
Close the computer cabinet, reconnect the power cord, then power on your computer.
The controller should boot correctly.
