Hello Felipe -
First, the t10.org<http://t10.org&gt; reflector is meant for the development of
the SCSI family of standards. It is not meant for technical support with any
given implementation.
That said, it seems both your Device Under Test (jscsi) and your testing
apparatus (sg3_utils) are elements of SCSI Initiator Devices. SCSI is a
client-server architecture. A working SCSI system requires at least one SCSI
Initiator Device (i.e. client), and at least one SCSI Target Device (i.e.
server), What target is in your system?
See SAM-5 for a description of the architecture:
For more detailed help, please locate an appropriate venue for such.

Hi, I am trying to test one iscsi target implementation
(www.jscsi.org<<a href="http://www.jscsi.org/&gt">http://www.jscsi.org/&gt;) with
sg_modes<http://sg.danny.cz/sg/sg3_utils.html&gt; and
sdparm<http://sg.danny.cz/sg/sdparm.html&gt; commands.
Is that possible? I didn't find any example at the internet. Is there any
commands that I can simulate my initiator sending MODE SENSE 6 and the target
responding? Maybe I am searching for wrong things....
I want to test MODE SENSE 6 (Control mode page) that I have to implement to
this target.
