Do you have some module that is hooking into the scsi layer or iscsi modules? Just wondering what the "sim_try_to_abort_cmd" call is. Where are you hooking in? Have you also modified the iscsi tools?
During this test, is the target able to respond to iscsi level IO, but just not scsi commands? I see iscsi nops are successful, but the scsi scan related commands like REPORT_LUNS are never replied to by the target. The scsi error handler then runs. Some aborts work, but eventually we do not get a response to one, and that results in the device getting offlined. I then see something is trying to delete the session (the upstream iscsi tools would normally not do this). It then looks like we hit a bug in the scsi layer. The scsi layer keeps trying to send a inquiry, but because we are deleting the session, the iscsi layer fails the command with DID_TRANSPORT_FAILFAST. This then goes on for minutes until you stop taking the trace. To debug this some more, we will need to get some scsi layer tracing. Did you run that scsi_logging_level command? Could you also check the current kernel?
