Subjectspin up/down scsi ioctl
<HTML>

<PRE>Hi all,</PRE>

<PRE>I have a noisy Quantum Grand Prix Wide SCSI drive which I use to store backup</PRE>

<PRE>things and cruft...</PRE>

<PRE>This drive is quite hot as it works at 7200 rpm and with one more 7200 disk plus</PRE>

<PRE>2 Ppro at 200Mhz my box was becoming real hot...</PRE>

<PRE>Digging around I found a small package 'scsi-idle' which added 'spin up/down'</PRE>

<PRE>ioctl to the kernel scsi disk subsystem and a tiny daemon to spin down scsi</PRE>

<PRE>disks after a predefined amount of time...which seems to work with my scsi</PRE>

<PRE>host adapters (2 x bt-958 + 1 x bt-946C) and disks (quantum xp32150w +</PRE>

<PRE>quantum xp34301) kernel 2.1.44-pre2</PRE>

<PRE>This is very similar to the adaptec ez-scsi facility to spin down idle hard</PRE>

<PRE>disks..( which, BTW, I use in another box running NT4...)</PRE>

<PRE>I attach the original version plus a (minimally) modified version for linux-2.1.43</PRE>

<PRE>with the hope that this useful ioctl will be included into mainstream kernel...</PRE>
