Description
smartd.conf(5) says "-n POWERMODE" only works on ATA. My testing shows this might be true, even though smartctl(8) shows "-n POWERMODE" has experimental support for SCSI.
Either way, it shouldn't be too hard to make it work in the generic case. sdparm has a way to detect when a SCSI and SAS disk is spun down:
