 	I was't able to find anyone that had got this to work in the way I 
was trying to do it.  The consensus seems to be (and somewhat verified by 
testing) that only the Sun QLogic drivers will work with mpxio, not the 
Qlogic ones.  I am using the non-Sun QLogic cards.  I did consider 
flashing them into Sun cards, but I didn't try it.

 	I was also unable to QLogic's SANsurfer software to do failover 
either.  I'm going to try to contact their support people and see if I can 
get a response.

I've included my original post below.
