What do I need to do to get it to recognize my volume group so I can

Sorry, poorly formed question. Let me try again.
I'm trying to rename my volume group. I have one drive with a non-LVM
boot partition and then the rest of the drive is LVM'ed, I have another
drive on the box - single partition, entirely LVM'ed.
From all indications I should be able to boot up with the fc6 rescue
cd, do a vgrename, change the /etc/fstab and grub.conf to reflect the
new name and life is good.
So I booted up with the rescues cd, did not enable the network, skipped
the search for fedora installations, and ended up with a command prompt.
At this point I should just be able to do a
- lvm vgscan
- lvm vgrename
I can't get past vgscan, it doesn't find any volume groups. If I try
vgrename --test oldname newname it fails because it still can't find any
volume groups.
ls /dev shows nothing volume group related. vgscan --mknodes, and
vgmknodes both do nothing.
This has to be something stupid I'm not doing but I am at a loss. Given
the VolGroup00 naming the fedora applies by default I can't imagine this
hasn't come up a lot yet none of the solutions I have found are
applicable. Can anybody point me in the right direction?
Thanks!
4 questions:
A. What's your hardware configuration. (Controller, drives, etc)
B. Stupid question - does F6 even recognize your storage; Can you see
something in the kernel
log? /sys/bus/scsi/devices/? /sys/bus/ide/devices/?
(Don't forget that the rescue CD is based on a far older kernel.)
C. Have you tried F7/8 rescue CDs?
D. What does pvscan return?

B. According to fdisk it sees all of my storage, LVM doesn't seem to
though.
C. I just tried the FC8 rescue CD, it behaves the same. I should have
tried that before posting...
D. pvscan returns the boot drive only and does not place it in any
volume group.
Also, I see after I tried the FC8 rescue CD that all drives are seen by
the kernel as scsi. The output above reflects booting into FC6. My two
IDE drives are older IBM's scavenged from other machines to cobble
together a file server using the SATA drive.
Thanks for all of your help.
