Possible to spin down a scsi disk?

[Rob Browning]

I poked around the scsi driver source (linux-2.1.79 scsi.c, sd.c and
aic7xx.* if it matters) and tried to figure out if there was a way to
spin down a scsi disk comparable to the trick you can do with IDE
drives and the "hdparm -t" command.  I could see where the drives are
spun up if necessary, but that's only at startup.  I have a couple of
drives in the machine that are normally not even mounted, so I wanted
to spin them down when they're not in use.  They're loud and *hot*.

I'd appreciate pointers to the relevant info (if this is even
possible).

Thanks
