Yes ofcourse. Iâve also set the Inquiry page 0x83 to show both ports.

Guy,
Have you set the MultiP bit (bit4 byte6) of standard INQUIRY?
From SPC-2 Standard INQUIRY description:
A Multi Port (MULTIP) bit of one indicates that this is a multi-port (two
or more ports) device and conforms to the
SCSI multi-port device requirements found in the applicable standards
(e.g., SAM-2, a protocol standard and
possibly provisions of a command set standard). A value of zero indicates
that this device has a single port and
does not implement the multi-port requirements.
Regards,
Kevin D. Butt

Hi,
I'm trying to develop a working FC multi-port target device. To be concise,
I'd like to get an Initiator to see the SCSI target device LUN as dual
ported. Both SAM-2 and SPC-3 contain some directions but they don't seem to
do the trick. Looking at multi-ported RAIDs and how they do it, I've come
to understand that vendors use specific pages and parameters to convince an
Initiator of their Multi-Port abilities.
Is this documented anywhere?
Thanks,
-Guy.
