I thought I'd learn alittle about the SCSI subsystem and it was 
documented in the source.  I should point out that many things 
can be controlled by writing to the /proc subsystem.  A simple one
would be ip forwarding a more complex one is the Mylex block driver
for the DAC960 SCSI raid cards.  I'm not at all sure how it works,
but it does.
