As far as I can tell, It's stored in the PVs themselves
(when I boot ubuntu it finds all my Debian LVs, for example) .
You should be able to drop a disk in elsewhere
and have a vgscan/pvscan find it (which happens at boot normally).

/etc/lvm/lvm.conf mainly configures how pvscan etc work, so unless
you tweaked that it should'nt be necessary to change it on the other
