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.

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 ?
