I have a Windows 7 workstation, using a LSI 9280-4i4e card, with a 4 drive RAID5 volume.
MegaRAID controller policy is set to idle drives after 30 minutes.
The OS power policy is set to spin the drives down after 30 minutes.
This works fine, drives spin down when not in use.
I built a new Windows 8 workstation, using a LSI 9271-8i card, with a 4 drive RAID5 volume and a 4 drive RAID10 volume.
MegaRAID controller policy is set to idle drives after 30 minutes.
The OS power policy is set to spin the drives down after 30 minutes.
The drives never spin down.
The same happens on multiple machines, and with Server 2012.
I found a LSI KB that says that Dimmer Switch III DS3 has been removed from newer controllers and firmware:
http://kb.lsi.com/KnowledgebaseArticle16590.aspx
LSI has not released any drivers for Windows 8 or for Server 2012, but the inbox drivers included with the OS install appears to work.
It is very important that all drives spin down when not in use.
If LSI truly removed this ability, I will need to find a different RAID manufacturer.
Any insight into why drives don't spin down on Win8 and W2K12?
