not visible on the ESXi LUN iSCSI hosts

So I have a bit of a strange and hoping the community can help me to understand. In my lab at the House, I have 3 x ESXi 5.1 Build 799733 hosts x 2 guests are the same hardware (BUD Intel) and the other host an old HP flat desk. I am running CE Nexenta 3.1.3.5 on a Microserver HP which provided the iSCSI storage to HP desktop computer. The 2 new Intel NUC VMware hosts however, I am unable to get any iSCSI storage visible to them. Software iSCSI adapter is enabled, peut vmkping storage to the host and the target will appear on the static discovery tab. The configuration appears to be identical between the 2 However, the hardware is different... I have a new analysis on the host and no devices appear. Now the obvious answer is there must be a security issue on the side of Nexenta... but the 3 hosts are all part of the same group initiator. Confirmed and copied the IQN name over and over again. I still think that this is maybe a matter of Nexenta, but maybe it's something else.

Check the vmkernel.log file contains the following information after a new analysis...

(2013 06-09 T 23: 49:06.412Z cpu3:2931) SFS: 4972: pilot no. FS claimed "on the remote control": unsupported

Anyone got any ideas?

Problem solved.

Appears that it was a problem of connection iSCSI ports. There is only a single teddy bear in each of these hosts and allowing the port bindings vmkernel on initiator iSCSI under 'Network Configuration' result not being iSCSI target devices is not visible. Removed the vmkernel port binding and made a new analysis. Cameras then showed upward.
