It took me way longer then it should have but I finally got my Dell PowerEdge 4400 with PERC 2/DC RAID Controller working. After trying Debian 4.0, Fedora 7, and CentOS v5.0 I was finally able to find a distro that _noticed_ my RAID controller; Ubuntu v7.04 Server. It installed without a hitch but coming up after its first reboot was a different story. After a long pause while booting it finally threw a “i20:iop0: could not activate controller” error. After some googling I found this posting on the Ubuntu forums. The “CTRL-M I20 to Mass Storage” fix work beautifully. I now have a another working server to play with…JOY!!!
