Mike,
Thanks, that helped a lot. I ended up find a cli command to disable ipv6 on
my targets as well. Im still getting some errors when I start the iscsi
service though. Here are my results:

I don't see any reason why it would be trying to logging in twice.

If you are getting ipv6 addres like above then you need to modify your
target. When iscsiadm does discovery the target is returning those ipv6
portals and iscsiadm is just printing out what we got.
So basically going back to the problem of the iface portal match up too,
when iscsiadm does sendtargets to -p 10.0.0.1, the target is telling us
about all the portals on the target. There is no way to ask it just for
portals that can accessed though a specific iface. It just tells us
everything it knows. iscsiadm will then setup the db so that each iface
in /etc/iscsi/ifaces or that is passed into it with the -I argument are
setup to access through the target through each portals returned. So if
you do:
iscsiadm -m discovery -t st ........ -P 1
you will get a better idea of the mappings.
I think what you have to do is edit the results by hand:
# do discovery and setup with one iface
iscsiadm -m discovery -t st ........ -I iface0
# manually edit so we do not access second portal (assuming we do not
want to access 10.0.1.1:3260,1 from iface0)
iscsiadm -m node -I iface0 -p 10.0.1.1:3260,1 -o delete
(Instead of deleting you could also just set the node.startup to manual).
Then you need to rerun the above commands for iface1 and other portal.
This ignores the ipv6 addr problem because there is nothing we can do
from the open-iscsi side except manually delete those records. To not
have to edit it on the open-iscsi side you need to edit the target to
not tell us about those portals.
