One more point, if you get to the point of mounting the DASD__, say to
/mnt, I would then
chroot /mnt
zipl
you can now proceed to IPL from this DASD/partition.

Ranga:
if you can bring up another Linux guest, can you vary the DASD/partitition
on-line and run an "fsck /dev/dasd__" to check and fix consistency before
mounting it?
Once fsck does its job, i would make sure you can issue the mount and ls
the file system.
I would also do a restore of the DASD before running fsck. I suspect your
first mount (during IPL) may have damaged the content of some key files on
the DASD/partition you are working with.

Please respond to
Linux on 390 Port
We are in the midst of a disaster recovery exercise. One of the Linux
guests is not coming up after failing fsck check. Nor would it let me do
it manually as it says the partition is mounted rw. I can unmount and run
the fsck. On re-boot, the problem recurs. The root partition is formatted
as reiserfs and fails fsck. At this point no other partition is mounted.
df shows duplicate root partitions - exactly the same geometry. Back at
the ranch, everything looks good. I even restored the guest as of the
beginning of May to a second level and it comes up without problems.
The only thing I can think of is to bring up another guest with its own
root partition and other partitions from this sick guest.
If anyone encountered and recovered from this I would appreciate it.
Somehow I can not think how the environment, VM or anything else could
affect what is inside Linux.
The guest directory looks like this.... (Note the 100x minidisks were
added to created a volume group). There is no NFS or any other fancy mount
here.
