Perhaps something worth trying is the following - It's what I have to do
to get the promisc card I use to rebuild:
- Identify the channel the drive is on (ie ad6 on ata3)
atacontrol detach ata3
atacontrol attach ata3
atacontrol addspare ar0 ad6
atacontrol rebuild
The command exits straight away but if you run: atacontrol status ar0
I get a 'REBUILDING 0%' message
Also checking the ps output shows a rebuild thread.
Might work, for you.
Cheers,
Benjamin
