Unable to Mount an iSCSI Partition after Initialisation

I am using a Thecus N7700pro NAS with an iSCSI LUN. I have installed and configured the globalSAN Initiator and have successfully connected to the iSCSI target.

In Disk Utility I am able to see the new LUN and am able to create a single 1.3TB partition using Mac OS Extended (Journaled). The operation appears to complete sucessfully but the log shows that the volume failed to mount after the erase and format.

Any ideas would be most appreciated.
