1394 storage

Hi all,

I need to write a driver for a native 1394 storage device. I just went
through the SBP-2 spec. I’m not clear ultimately what commands are send to
the storage device, say I need to read a sector - so what command should my
driver send to the 1394 bus driver? There is a Command_set and
command_set_spec_ID filed in the Unit directory for a basic target according
to the SBP-2 spec.

Is it something that though the device is native 1394, it may support SCSI-
command set?

Any help is highly appreciated.

TIA
Pamitha
