LSM configuration lost

Hello all,

I'm in a sticky situation with my LSM configuration on an Alpha800 with 4
drives and tru64 5.1
The drives dsk0 and dsk1 are a mirror and have everything on them, system
and user files, there's only one partition used on dsk2 and it's nothing
useful, then dsk3 was supposed to be a spare.
I recently had a drive failure on dsk1 (dsk3 was not there at the time to be
used as a spare), so the system kept on going on dsk0 until I replaced dsk1
and manually re-created the mirroring, then added dsk3 as a spare. However I
wasn't able to create extra LSM configuration copies and the only one was on
dsk0 and some glitch must have happened with dsk0 which caused a reboot.
The system tries to boot normally from dsk0 and then can't find osf_boot and
stops. I manually force a boot from dsk1 and it only boots to single user
and fails bcheckrc during the disk naming and LSM can't start because no
configuration copy can be found.
I can't mount and other filesystems, so I don't have access to any useful
utility to help fix this and no access to a saved LSM config copy. All I
have is the root filesystem available.
All drives are 18gigs and basically only dsk0 and dsk1 are used, what is on
dsk2 isn't vital and dsk3 is just a hot spare.
I tried a few things but none worked because I don't have access to most
commands.
What could I try to start restoring this???
