FWIW I find it doesn't work on the Supermicro chassis (SYS-5019S-MR) we use
with SATA disks.
[chumphon 2:42] ~> sudo sesutil locate ada0 on
sesutil: Count not find the SES id of device 'ada0'
(Also I just noticed a spelling error in the above, "Count" should be "Could")

ses0:

Using led(4) works:
echo 1 | sudo tee /dev/led/ahci0.X.fault
(The X lines up with the "ahcich4" part of dmesg for adaX)
although I find you can only turn the LED on and not off which limits it's
usefulness somewhat..
