Erm, this makes no sense at all. You state you use the "iir" driver =20 for the card, yet you expect to see the devices under ATA ? Those are =20= two very different animals, you can't use them together in away way or =20= fashion on the same drives. That asks the question: which one is it ? If you use "iir" I have no idea how/if a rebuild is possible under =20 FreeBSD, however it could be in the BIOS or with any other OS that =20 supports it (here the HW should have kept your parity data intact). If you use ATA you shouldn't have used RAID5 as the docs tell you, as =20= there will be no parity data to rebuild from no matter what BIOS/OS =20 you use -> you will get garbage no matter what. > Thanks for the help and support.
