Just to make sure I understand. I run smpquery nodeinfo 0x1.
I get the GUID from that command and then run  ibnetdiscover and see if 
that GUID exists in the results?
If that is correct, the GUID does not exist, but when I run 
ibnetdiscover I see switchguids so I am thinking I am not doing this 
correctly???
