That's exactly what I want todo, but with drive cage LED's. Most hot
swap drive cages have 2 LED's, so I need a more universal approach,
i.e. irrespective of whether it's SuperMicro, Intel, HP, etc.
The page you suggested is very specific to the WARP devices, and by
the looks of it they have a script that runs in those folders, which
in turn interacts with the drive's circuitry.
but, I have yet to find a solution for generic Linux.
