Hi all,

Does anyone know how to control a hard drive light from Linux? I'm
building a 24bay Linux File server which will run software RAID and I
need an easy way for the engineers to see which HDD has gone bad.

Most of our NAS devices has 2 lights on the hard drive cages and they
automatically signal a bad one (reg light, light constant on , etc)
but I can't figure out how todo this from Linux.

Kind Regards
