Google (<https://serverfault.com/questions/907615/how-to-make-a-raid-disk-light-blink-on-linux>):

use "ledctl locate=/dev/sdd". Installed "ledmon". Doesn't work.

Google:

while :; do smartctl -a /dev/sdf; done;


Yes, this one works. Improved variant:

Telcontar:~ # while :; do smartctl -a /dev/sde; sleep 2; done 1>/dev/null
^C
Telcontar:~ #
