Peter,
Edit the VM file that gives permission's to the Linux guest to access your
VM disk. Remove
the permission for one of the Linux guest to access the disk where the /opt
file
system lives.
For us it's is disk 0202. See below:
more /proc/dasd/devices
...................
0.0.0202(ECKD) at ( 94: 8) is dasdc : active at blocksize: 4096,
60084
0 blocks, 2347 MB
df -h /opt
Filesystem Size Used Avail Use% Mounted on
/dev/dasdc1 2.3G 563M 1.8G 24% /opt
(This forces the Linux guest to boot into single user mode).
(Sorry, I'm a Linux person and not a VM person so don't know the correct VM
speak for this) Now do a hardware level reboot (#CP LOGOFF) for that
Linux guest.
and this will force the Linux guest to boot into single user mode.
In single user mode using a 3270 terminal you should be able to access your
Linux guest console. And now with a Linux prompt you can slow enable the
various
services in run level 5 (/etc/init.d/rc5.d) and differentiate what is
stopping you from
getting a Linux guest network prompt.
Hope this helps and is not to confusing

Peter,
Did you bring a copy of your installation media?
Could you boot it and then look at your restored system?
How many NFS mounts are there? Are you saying you
have waited 45 minutes and not gotten a message indicating
that one of your NFS mounts has been backgrounded or
timed out?
Have you tried setting up some system with the same
IP address as your NFS server, but not running NFS.
That way instead of timing out, you can get something
like connection request rejected. (I forget the exact
message). In some cases, this can hurry things along.
By the way, how did you backup and restore?
Ron
