All systems are clones of an original, so all device assignments in
Linux are the same across systems. Here is my ZIPL and FSTAB. I cannot
generate the error messages as I had to re-clone the system and get it
back online.
I was receiving errors on different filesystems and I ran FSCK's on
them, then received this abend in the kernel:
I restored the Linux volumes from the backup tapes and it will not come
up all the way. I switched tape sets with the same result. The kernel is
abending.

I think I might have an idea as to where your problem MAY be - I'm
guessing at this point so I'd like you to fill in some blanks....
Are your Linux guests device number consistent across Linuxen? As in,
/dev/dasdb1 is always device 601 and /{root file system} is 600, etc? Or
is it
on Linux A it's 600,601,602 etc and Linux B it's 400,401,402 etc? What
does your zipl.conf look like?
Also can you post any messages you get when you try to boot them?

FDR says working as designed. They back up the entire volume and restore
the entire volume. I have restored 3 systems and they DO NOT BOOT.

What do the FDR suppliers say?
