Thanks for the welcome to the forums also. Seems like we should list the version information so that others that try this configuration will know which versions have be verified to work? I see that there are a few people who have managed to get this to work but do not list the esx(i) build version or the firmware version of the iscsi terastation pro being used. Unable to connect TeraStation iSCSI to ESX or any linux host I've also checked the following locations for more information: I've tried enabling and configuring chap to see if that makes a difference which it didn't. I've verified that the kernel ports and service consoles can reach the terastations and the ip addresses are configured correctly.

I've looked in the terastation iscsi connection log and I get this error: Esx and esxi will both connect but neither will refresh a list of static targets (luns) sent back from either of the Terastations even after an hba rescan takes place. So on both boxes I have added 10.80.92.160 & 192.168.0.200 as dynamic discovery targets. On both network s I have a Terastation Pro II iscsi rackmount with the defualt array1 shared no chap iscsi service enabled. On the esxi box software iscsi is enabled (no firewall rules for it in esxi). On the esx box software iscsi is enabled and allowed on the firewall. The host ip for each box is in the 10.80.92.x network (esx kernel port & SC both with valid ip) (esxi kernel port with a valid ip) with an additional kernel port in the 192.168.0.x network for each box. The servers are configured the same but each with a valid ip address in each of the networks. I have both esxi 3.5.0 build 123629 and esx 3.5.0 build 64607 sitting on two physical networks (vm network 10.80.92.x (vSwitch0) & management network 192.168.0.x (vSwitch1) ).
