Thanks for the reply Stephen. lvdisplay -m on my system throws an error.
I guess I neglected to mention, this is on RHEL 3, which I guess uses
LVM1.  My RHEL4 systems have LVM2 and that command works fine.

Let me clarify my question a bit.  Are the pv numbers arbitrary?  Say my
kickstart file created during installation contains the following: 

part /boot --fstype "ext3" --onpart hda1
part pv.8 --noformat --onpart hda2
part pv.10 --noformat --onpart hda3
volgroup vg00 --pesize=4096 pv.8 pv.10

If I wanted to write a new, but equivalent kickstart file, could I use
the following:

part /boot --fstype "ext3" --onpart hda1
part pv.1 --noformat --onpart hda2
part pv.2 --noformat --onpart hda3
volgroup vg00 --pesize=4096 pv.1 pv.2

Or do the pv.#s actually correspond to a partition?  If so, how do I
derive that relationship from an existing installation?

Thanks,
