So i have a bit of a weird one and hoping the wider community can help me figure it out. In my home lab I have 3 x ESXi 5.1 Build 799733 hosts of which 2 x hosts are the same hardware (Intel NUCs) and the other host an old HP slim desktop. I am running Nexenta CE 3.1.3.5 on a HP Microserver which has been providing iSCSI storage to the HP desktop. The 2 new Intel NUC VMware hosts though, I am unable to get any iSCSI storage visible to them. Software iSCSI adapter is enabled, can vmkping the storage from the hosts and the target appears under the static discovery tab. The configuration appears to be identical between the 2 however the hardware is different...I perform a rescan on the host and no devices appear. Now the obvious answer is it must be a security issue on the Nexenta side...but the 3 hosts are all part of the same initiator group. Confirmed and copied the IQN over and over again. I still think it might be a Nexenta issue but maybe it is something else.
Checking the vmkernel.log file contains the following info after a rescan...

Anyone got any ideas?
