How can I be sure? How do I check?

This SAN exports another set of 4 LUNs to a different server and they 
work just fine.

pvcreate --version
   LVM version:     2.00.33 (2005-01-07)
   Library version: 1.00.19-ioctl (2004-07-03)
   Driver version:  4.4.0

pvcreate on the server that does not work is a little newer, so I wonder 
if there was any new code/bug fix(es) since this version that caused a 
regression.
