Probably, the incantation would have looked something like:
   pvscan
   vgchange -a y

It's good to see that you managed to rename it by UUID -- If I ever end 
up in this situation (as I have in the past), now I know what to look 
for. For personal machines I started naming the VGs like the host they 
originated on shortly after the aforementioned incident.

As to those who mentioned renaming the known VG, this can cause problems 
if your root is on that VG since the name tends to end up hard-coded in 
your initrd. Then again, it may just be redhat/fedora/rpath (the latter 
of which being what I am actually familiar with, and loosely based on 
the former).
