I've compared and found the difference between ietd and tgtd:

1. ietd returned "REPORT LUN (0xa0)" with only 1 LUN (LUN id 1, Type Disk),
   while tgtd report 2 LUNs, tgtd has the LUN 0 with "IET SCSI Controller"
   as the first LUN (LUN id 0), and "LUN 1" Type Disk;

Since ietd reported only 1 LUN that worked well, why tgtd should
report the superfluous
"IET SCSI Controller" as the "LUN 0"? Why the "LUN 0" cannot be
deleted with tgtadm?

Thanks,
