Then my case was different. Anybody else touching the yaboot.conf? I
have not seen this, so please let us know if you get to the bottom of this.

Hey George,
Yes, once I edited the /etc/fstab to reflect the change to /dev/vg0/root
and swap002 everything worked correctly. What is even more puzzling to
me is the fact that /etc/yaboot.conf file somehow was already using
/dev/vg0/root when I know from before they used the default
/dev/VolGroup00/LogVol00 LVM names.

Subject: Re: LVM Name Changed?
What can you see under the /dev/mapper directory? I recall seeing this
issue with a similar hardware config and the advice was to upgrade to
the latest release due to some issues with LVM. The problem however was
that there was fs corruption (changing manually the fstab entry did not
mount the fs in a clean way). Can you mount root on the system disk if
you change the fstab to /dev/vg0/root ?

I have a chassis IBM JS22 blades running RHEL 5.2 with a kernel.org

hit in the lab. I came back in this morning to find over half of them
dropping me into maintenance mode during boot. After several hours of
screwing around trying to diagnose the problem, I realized that
somehow
the LVM names had changed on these particular machines from
/dev/VolGroup00/LogVol00 and LogVol01 to /dev/vg0/root and swap002.
Has
anyone ever seen anything like this and if so, do you know why it
happened? Thanks!
