I think you can spin down only spare disks in the array!<br><br><div class="gmail_quote">2008/6/25 George Mari <<a href="mailto:george_mythusers@mari1938.org">george_mythusers@mari1938.org</a>>:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Anyone out there had any success with spinning down SCSI disks in a<br>
software RAID5 array for power saving?<br>
<br>
I tried to spin down one of my 4 disks in a RAID5 array, using the command:<br>
<br>
sdparm --command=stop /dev/sdi<br>
<br>
This spun the drive down (good), but it also kicked it out of the array.<br>
(bad)<br>
<br>
What I'm trying to do is just have it power down somehow after a certain<br>
time being idle, and then just spin up again when accessed without<br>
breaking the but it seems that SCSI drives don't have all the power<br>
management options that PATA or SATA drives do. (Or maybe just my<br>
particular SCSI drives don't have these features...)<br>
<br>
I'd love to hear from anyone with specific experience with trying to do<br>
this with SCSI drives - thanks.<br>
