Hi,

When trying to spindown the drives I have one that just refuses and throws an error. Any suggestions?

I see some historic posts on this but they all say it was fixed and mostly related to removable USB HDD's. This is internal SAS.

 

Logs and details below:

Unraid can't currently spindown SAS devices.

Hmm. Thanks.
I was sure the other server had SAS powerdown capability. I'll need to check later.
