I cannot create iSCSI targets from FreeNas. I was able to on the ESXi 4.0 but not version 5.1. I am able to see the targets on the Static Discovery tab after I entered the IP address on the Dynamic Discovery tab.
Here is the error log:
Login to iSCSI target XXXXX on vmhba37 @ vmk0 failed. The iSCSI initiator could not establish a network connection to the target.
FreeNAS 0.7.1 (Shere):
Check the authentication method .If it is CHAP ,you need the user and passwd.
Or maybe the issue of compatibility,so you can try higher version FreeNAS or other product such as iStorage Server.
