There is bug in the older tools where if you mix and match new style 
commands with old ones this happens. I think the one above was just 
busted though. I have no idea what is in ofed.

If you set a tpgt when you create the node does it work then?
# iscsiadm -m node -T 
iqn.1986-03.com.sun:02:aff22998-3466-4bf4-ee3c-958fd4b5d346 -p 
10.8.0.6:3260,$whatever_is_the_tpgt

You do not have to set a valid final tpgt. When we login a normal 
session we will use what we find. But it should work around the issue in 
the ofed tools.
