I'm trying to understand what a WWNN/WWPN/IEEE number is.
I have a Solaris system with two single port HBAs attached to a Clarion through a fiber switch.
In the /var/adm/messags file I see WWNN and WWPN numbers for both HBAs, lpfc0 and lpfc1. From these numbers I see that the WWNN is the same so I assume the WWNN number is unique to a host while the WWPN number is unique to a HBA/Port.
When I run lputil and look at the IEEE number I see it's the same as the WWPN for a HBA.
When I run lputil and look at persistent bindings I see different WWNN and WWPN numbers. Where are these numbers coming from ? The Clarion ? Fiber switch ?
