Yes, it should work the same as ami/mfi. ie: hw.sensors.arc0.drive0=online (sd0), OK hw.sensors.arc0.drive1=online (sd1), OK hw.sensors.arc0.drive2=online (sd2), OK hw.sensors.arc0.drive3=online (sd3), OK hw.sensors.arc0.drive4=online (sd4), OK hw.sensors.arc0.drive5=online (sd5), OK hw.sensors.arc0.drive6=online (sd6), OK hw.sensors.arc0.drive7=online (sd7), OK hw.sensors.arc0.drive8=online (sd8), OK hw.sensors.arc0.drive9=online (sd9), OK hw.sensors.arc0.drive10=online (sd10), OK If you have an sgpio enabled controller you can toggle LEDs on disk bays etc.
