Reinstalling RAID Drivers


D

DSt

Hi all,

I have a Dell PowerEdge 2500 server, which has a PERC 3Di RAID
controller in it, attached to two 36G drives, which are mirrored,
running Windows 2000 SBS.

We have been having problems lately, where one drive has been going
offline - so the other day, we tried to install some of Tools from the
Dell website, for diagnosis - unfortunately, one of them, it would
appear, has somehow deleted or replaced the correct driver - after
restarting (to complete an install of one of the tools), we now get a
STOP Error: INACCESSIBLE_BOOT_DEVICE.

The drives are online at the moment, the array is intact and the data
seems to be on the disk (I've used a boot CD to get in and check the
data) - so I'm thinking this must be a driver issue - especially given
the nature of the stuff we were installing at the time.

So my question: How do I get the correct driver installed if I can't
get into Windows? I have the 2000 SBS install media, so I can run
Recovery Console. I also have a valid, full, NTBACKUP backup of the
system, again if that's any good (I was going to restore System State
- but again, I can't get into Restore Mode because it won't boot).

HELP!

Thanks in advance,
DSt.

Try loading the controller driver from floppy. For the floppy to
successfully boot Windows 2000 the disk must contain the "NT" boot sector.
Format a diskette (on a Windows 2000 machine, not a DOS/Win9x, so the "NT"
boot sector gets written to the floppy), then copy ntldr, ntdetect.com, and
boot.ini to it. Edit the boot.ini to give it a correct ARC path for the
machine you wish to boot.

In order for this to work you'll want to change the arc path in boot.ini
from multi syntax to scsi syntax to indicate that Windows 2000 will load a
boot device driver and use that driver to access the boot partition. Then
also copy the correct manufacturer scsi driver to the floppy but renamed to
ntbootdd.sys


Something like this below;


[boot loader]
timeout=10
default=scsi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
scsi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows 2000 0,1"
scsi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows 2000 0,2"
scsi(0)disk(1)rdisk(0)partition(1)\WINNT="Windows 2000 1,1"
scsi(0)disk(1)rdisk(0)partition(2)\WINNT="Windows 2000 1,2"

Dave,

Many thanks for taking the time to reply, but I've just fixed this
issue, and it turns out it wasn't a driver issue. It was the problem
as described here: http://support.microsoft.com/kb/822052#6b.

I got the system up using bcd4win, and deleted the reg entry it
referred to, and voila!

Thanks anyway,
DSt.
