If I have two 1394 cards A and B in a system, they should each be created in LIO as two different lio:targets using /sys/bus/firewire/devices/fwX/guid (since lio:target <-> 1394:device) and only those where ./is_local == 1 (in kernel 3.6+) Next I'd create a tpg (tpg1) for A, and this would create a 1394:unit_directory of type "sbp target" on A. Then I'd map storageobjects to tpg1, and this would add the LUNs to the 1394:unit_directory. I plug in to a port on card A, I see the LUNs. I plug in to a port on card B, I get nothing. Yes?
