Hi there,
i am sitting on this one for days now and haven't found any solution to the problem yet. I've setup FreeNAS 9.10.1 to be an iSCSI-Target and the extent is recognized well by Xenserver 7. However, as soon as i want to establish a connection via XenCenter to install a VM on the Target, the connection gets dropped by FreeNAS and both interfaces (FreeNAS+Xenserver) go down. I am using Intel Pro 1000PT Dual NICs (lag/roundrobin) and i've read that there could be a bug in the em driver considering tso. I've disabled tso on both sides but the problem remains. I've also set "kern.cam.ctl.iscsi.ping_timeout" to zero because i got a No-OP timeout message (that now disappeared).
These are the last lines of /var/log/messages:
Xenserver says this in dmesg:
It would seem like an DNS issue but name resolving works and everything is setup correctly. Sometimes mdns says:
I can partition the iscsi extent on Win 7 just fine and work with it. It might only occur under heavy load such as installing a vm over network...
Any help is greatly appreciated!

Xenserver says this in dmesg:

It would seem like an DNS issue but name resolving works and everything is setup correctly. Sometimes mdns says:
Code:

I can partition the iscsi extent on Win 7 just fine and work with it. It might only occur under heavy load such as installing a vm over network...
