Comment 15 for bug 1794219

per test today, I set up the vroc nvme raid on a dell machine.

On that, I can use a command like

ledctl locate=/dev/nvme0n1

to make the led on the encluse module blink.

And use command

ledctl locate_off=/dev/nvme0n1

to make the led stop blinking.

As I config two nvme a mirror raid as the boot device, I run below command

mdadm /dev/md126 --fail /dev/nvme0n1

If the ledmon daemon is installed and running, then with the above command, the led on the enclosure will start to blink.

If ledmon is not installed and running, the above mdadm command won't make the led blink.

Given so, I think ledmon is useful for these use cases. I think we should consider including it in main.
