The problem is for iscsi the scsi initiator port / transport id, is the initiator name and isid. The isid is just a 48 bit number and the initiator will allocate a new value for every session. So on the initiator side if there are multiple nics, then it is common to create a session through nic and each session will have the same initiator name but different isids. So at some place you need to put multiple files to export the different isids or indicate to userspace tools that there is more than one session connected to that tpg.
