Can you copy the output here?
I'm curious how it's reported.

the sg driver is a passthru interface and doesn't present a "random
access mass storage device" view. sg would be used to configure
the MUX and sd to access the devices behind it.

My point was the existing FC interface drivers already present FC
storage devices (eg disks or arrays) via "sd" driver and don't know how
to talk to devices that aren't "transperent" (ie invisible nodes in the
FC fabric).
