Hello List, i was looking for a way to access a drive LED from user space to make it blink. If found some solutions (ledctl, sgio,..) but these do not support AHCI. I found this patch: https://lwn.net/Articles/256322/ so there is a cmd. But i was unable to find a ioctl() or /sys/something that would allow me to controll the leds. (did i miss something) Interesstingly bsd seems to support this: https://www.freebsd.org/cgi/man.cgi?ahci(4) so it seems possible. (I do not use bsd no idea if it works) please reply directly, i am not member of this mailing list.
