You want scsi-spin. I'd suggest getting it out of woody, in the scsitools package. There's recently been a minor documentation fix done on it.
I use it from /etc/init.d/halt on my headless all-SCSI machine so I know when I can turn it off even when I don't have serial console up. It's an OEM drive out of a Sparc that sounds like a jet engine. On Fri, 28 Jul 2000, Simon Hales wrote: > > Hi > > Thanks for the quick reply, but unfortuately, no luck.
