I guess that's one of the reasons why many people still use hardware RAID adapters.. (firmware of the hardware RAID adapter takes case of the SES/LED management.) Someone should start an opensource project to build this kind of management daemon for software RAID on Linux. It's not very difficult.. someone just has to do it :) The only solution that I'm aware right now is Linux dm-raid.. I think it can handle some LEDs on some chassises. But that's implemented in kernel-driver.. -- Pasi
