iscsi 10gb fiber and xenserver issues

[shiftenterprises]

Okay, here is my setup
FreeNAS-9.3-STABLE-201601181840
I have a 10gb card with dual ports sfp+
I have two dell poweredge servers with 10gb cards in them as well sfp+
Both servers are running the same version of xenerver.
I have each server directly connected with multimode 10gb fiber
-----
Currently my 1st xenserver server can see the storage block i setup in iscsi.
freenas ip is 10.0.0.2
server 1 is 10.0.0.3
----
Server2 is 10.0.0.4 also and connected to the second port of the freenas.
I cant see the freenas, even after trying to create a new subnet it just wont work.
Im trying to create a xenserver pool and have the shared storage across both servers.
I have tried doing lacp, and when i do that my first server loses connection to freenas.

I am at a total loss on how to set this up

You've given us very little to work with here. Please consider posting a detailed hardware manifest that consists of more than a FreeNAS version number and a 10G card, plus other supporting info.

I am sorry, i was 37,000ft in the air crammed trying to get a reply on a three hour flight.
I am not sure what else i can give you, I have some t320 cheslio cards in the servers. The freenas is a 12 bay 4tb per bay server in raid z3-0 with ssd cache.
the target is a 4tb dataset that im trying to share with both xenservers.
The plan was to use two exact xenserver nodes with the same fiber cards directly connected to the freenas via fiber.
Xenserer HA requires a shared storage on the pool.

Please let me know what else i can provide here to get a little advise. I am currently doing cross country road trip with 12 hours left in my journey terribly sorry if i leave something out. not sure how much detailed i can get.

There's a ton of information I've posted on block storage for VM usage available on the forums; basically it comes down to:

1) use mirrors not RAIDZ,
2) leave lots of free space,
3) give it gobs of RAM (64GB++++)

Without more specific information about your equipment, your workload, and your design goals, there's only so much gassing on I'm willing to do on a cellphone while at the beach.

You can not assign same subnet on two different FreeNAS ports. If you want to do direct wiring -- assign IP from different subnets to each one.
