HELP! - Corrupted Mirrored Root & Usr

Hello all,

I'm desperate for your assistance.

I have 4.0F with LSM mirrored root, usr, filesystem, and raw (used by
Informix) disks.

I tried to do a upgrade to 5.0A (destination 5.1) but it died with the
libx11.so error. Now the root and usr disks are corrupted with a dodgey 1/2
installed system. I did a restore of a tape from 2 nights ago of the root
and usr partitions by booting off the 4.0F CD and mounting them as rz0a and
rz0g. This failed to boot because the mirrors are out of sync.

I'm not concerned about the root and usr disks, but all the rest I am
desperate to save. The tape backup I made just before the shutdown is
corrupt.

I have a method to restore to a recent point but I want to see if I can get
it back to the exact point in time.

Thanks,
Damien.
