It doesn't work for the reason I mentioned below -- the driver says that the firmware included in the driver does not support multiple ports. ("non-MULTIID f/w loaded") I did a quick experiment, and commented out the check, and was apparently able to enable multiple ports in CTL. CTL just saw more target-capable ports. But my FreeBSD initiator had some definite problems connecting to the target with multiple ports enabled. > On Tue, Dec 10, 2013 at 1:53 AM, Kenneth D.
