Why do you say that? Have you found some configuration in which this does not
work?
>From the spec pg 905:
"Note: If a channel adapter or router has multiple ports on the same subnet,
there will be multiple NodeRecords available for that node from SA, one for
each possible PortGUID value of NodeInfo for that node on that subnet."
So each NodeRecord should have a unique port GUID in it.
Or do you think the GID interface ID will not always equal the GUID? I thought
I read that somewhere but perhaps I am wrong. I don't find it right now. :-/
