And my $0.02 worth. Sell/return the promise card, it sucks. Surf over to www.3ware.com
and get a new/better card.
The promise cards are not hardware controllers, they are most ran by software (your CPU cycles).
The drivers and linux support in general simply sucks.
3ware on the other hand is geared for linux.
Their drivers/management software is geared for linux and in top notch.
It is truly a hardware controller.
And is overall a much nicer card than anything promise offers.
I had a promise SuperTrak SX6000 Pro for just about two days before i sent it back and got a 3ware 7506-8. There is absolutely no comparison between these cards in a linux environment.
