The latest wwpn tool predicts physical wwpns too.  The physical wwpns are
the ones that are used when NPIV is off.  A physical wwpn starts with
several digits of the IO serial number + pchid + 1.  For example, pchid
192 on one of the machines that I have access to is C05076FFFC001921.  I
think physical wwpns are much easier to work with now.
