mirroring and fault tolerant boot disk

by bradsayers . Updated 25 years, 7 months ago

I have a have a question that baffles me.

I installed a second hard drive (as a slave, primary IDE) in a NT 4 server (NTFS) and mirrored them.

The system boots fine and in disk manager, I can see both drives mirrored and in a healthy state.

The mystery is this: I cannot boot to the second drive with a fault tolerant boot disk. I have researched mirroring and performed all the following possible resolutions:

I have went back and deleted the partition on this new drive, then created and formatted it with NTFS according to Q117131, writing master boot record to shadowed partition. Then I established a mirror.

After mirroring, I updated the repair information (rdisk /s) then did a emergency repair process with the setup disks to write MBR info to the shadow disk, see:
(http://www.ntfaq.com/Articles/Index.cfm?ArticleID=14673).

After all this I made a fresh fault tolerance disk as follows:
ntldr, ntdetect and boot.ini.
Fault tolerant Boot.ini looks like this:
[boot loader]
timeout=15
default=multi(0)disk(0)rdisk(1)partition(1)\WINNT.SBS
[operating systems]
multi(0)disk(0)rdisk(1)partition(1)\WINNT.SBS=”BackOffice Small
Business Server” /NoSerialMice:COM1
multi(0)disk(0)rdisk(1)partition(1)\WINNT.SBS=”BackOffice Small
Business Server [VGA mode]” /basevideo /sos /NoSerialMice:COM1

The boot.ini on the server reads rdisk(0).

Whenever I boot from the FT disk, the boot process gets to the same point before failing. I believe this is where ntldr loads the ntoskrnl.exe. I get the blue screen which says Microsoft Windows NT (TM) Version 4 (build 1381), however the rolling dots underneath that sentence never come and I am sent back to a restart.

As I have indicated: Disk Manager reports ahealthy mirror.

But I really want a fault tolerant boot disk (AND to understand what is happening!)

Thanks for any help, Brad
