Yes, I have noticed it.

With the creation of an empty file, it started to display the lun1.

However, from the initiator, still not be able to see the target - from the lsscsi, no other devices (controller/virtual-disk) than those physical devices available on the fabric.
Instead, the host with target-mode displays following messages,
---
Oct 3 11:21:13 atl-01 kernel: q2t_it_nexus_response 1191: dff46400 0

If I understood correctly, the F/W on the host with target-mode should have gotten some SCSI commands from the host with initiator-mode by now.
And those commands should have been forwarded to the target driver via the interrupt handler (qla24xx_intr_handler()).
Just for my learning, could you share with me which of the F/W version (on the target-mode QLogic FC HBA) you are using?
Thank you,
