The most correct thing is to boot in rescue mode off either CD #1, the
rescue CD or the DVD. At the "boot:" prompt, enter "rescue" and press
ENTER. When the system asks if you want the system disk mounted, select
"Yes".
When the "#" prompt comes back, the root filesystem of the crashed
system will be mounted at /mnt/sysimage. Edit "/mnt/sysimage/etc/fstab"
and comment out the lines referring to "/mnt/raid" and "/mnt/raid2" and
save the file. At the command prompt, enter "exit" and the system will
pop out the CD/DVD and reboot. The original system should come up
WITHOUT trying to mount the crashed disk.
This is precisely the type of thing that rescue mode is meant to do.
