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.

we use the following workaround:

- trigger the activity light by running "hdparm -tT /dev/sdX" for the drive in question - watch the lights of all the drives - the one that blinks is sdX; this of course works best if the array is idle

This is of course very low-tech, but it does the job.

HTH,

Kay
