mirror disk / boot

[Sandy]

ok - i've asked this before - and I thought I did
everything right - but yesterday one of my servers
primary harddrive died. The server was mirrored. I had an
emergency disk for the server which had:
boot.ini with the right scsi rdisk
ntldr and a commond file in the i386 directory.
I took the bad disk out
put the emergency repair disk in
and received could not find ntldr - and the computer
wouldn't boot - just sat there laughing at me.

we had to switch the controller cables to fake out the
drives so the system could boot.
configuration 2 channel scsi.
channel 1 had one drive
channel 2 had the other drive

why wouldn't the emergency disk work - shouldn't it had
booted?

thanks

The boot diskette would need the files boot.ini, ntdetect.com, ntldr and
possibly ntbootdd.sys (if the scsi() syntax is used in boot.ini. The
diskette must also be formatted from within Win2000 (I suppose this is your
operating system) in order to have the correct boot sector.

Also, your BIOS must be set to boot from diskette before hard disk.

that's interesting - ntboodd.sys - that isn't on the floppy.
OS is Win2k latest service pack/hotfixes.
floppy has: boot.ini (which references a scsi drive)
directory winnt\servicepacks\i386\
with ntldr and ntdetect in the i386 directory...

I created the emergency backup disk from the OS on the server that needed
help --- how would i tell it to load ntboodd.sys - or do i just copy it
over?

All of the files needs to be in the root of A:\, not in a folder.

If the ARC path in boot.ini starts with scsi() instead of multi()
ntbootdd.sys is automatically loaded from A:\. Ntbootdd.sys is just a copy
of your hard disk adapter driver.
