It's fairly straightforward. The one tricky thing is that you have to login (VN2VN) on both sides before setting up the target. This way you can get the WWPN that you need for target CLI. In a nutshell, you're going to do this: 1) login both sides (initiator and target) (echo create_vn2vn) 2) run targetcli 3) create a disk 4) create a WWPN (from the target fcoeadm -i) in tcm_fc 5) create a WWPN (from the initiator fcoeadm -i) in acls under the target WWPN 6) add the lun to the luns/ Here's the output of a working setup I have, /tcm_fc/20:00...:17/luns/lun0> ls / o- / .......................................................................... ...............................................
