Yes ofcourse. I’ve 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.
