Inaccessible boot device

[Antony13]

Hi all,

I'm getting a problem where I'm attempting to carry out a DR test on one of my AD domain controllers. The system runs on a Dell PowerEdge 2550 and I'm trying to do a restore on a PowerEdge 6650 (as we don't have spare 2550s). After I've built the new machine in our test lab with same name, hard drive configuration etc. I then do a system state restore and on reboot, get an INACCESSIBLE_BOOT_DEVICE error (presumbably because the RAID controllers in it are different).

No matter what I do after this though, I can't get the thing to boot in any of the modes available. I've tried making an ERD before I do the restore and then running a repair from the 2000 CD with this ERD afterwards but it still doesn't fix the problem. I did the same test on another DC we have running on a Compaq Proliant restoring to a Compaq Deskpro and this worked fine.

Anyone got any ideas if anything else I can try?

Thanks, Antony

Hi guys,

Possible update on this - I've had someone else come to me about this with the same problem and they said they were restoring a DC from their root domain which worked okay but it was the restore of a DC from the child domain which failed which is exactly what I'm getting. Because one was running on a Compaq and the other a Dell for me, I assumed it was down to hardware but it's possible it's a problem with Active Directory restoring child domain DCs.

Has anyone had this problem?

Any suggestions appreciated.

Cheers, Antony

For anyone following this, the Microsoft article:

http://support.microsoft.com/default.aspx?scid=kb;en-us;263532

provides some good pointers, as does the AD Disaster Recovery document:

I've yet to complete this successfully, but got a lot further than I do before I read this and also think I know where i went wrong! As and when I do get it, I may well write an FAQ on it so keep your eyes peeled for this.

Cheers, Antony

If you are using a different scsi controller, you will need to update the driver (.sys file) on your boot partition in the root of the drive. If your scsi configuration of the drives is different (different LUN) you will need to update the boot.ini to point to the proper disk location.

Same problem with restoring the system on the same compaq hardware (diferent disk): "Inaccesible boot device".
The disappeard when we used a newer version of the raid-controler driver when installing the temporaraly Windows 2000.
After the restore is seems to use the old drivers, rather then the drivers on the tape.
Can anyone explain this?
