Ok. Let me look to see if we can do this. If so, we should be able
to help contribute some scripts.
I've been doing this for a while. In SES the various elements (slot,
power supplies, fans, etc) are named. At least if your JBOD vendor

values and modify bits to assert control. Once you know the names of
your elements you can address them by name for status and control
(fault LED, power on/off, temps, etc).

so that when a disk fails, the kernel module that failed the disk can
light up the LED.
I work for one of those vendors, it's my job to have our **** together.
