Distro Install Fails

I have a dell 2950 running 2 sas drives with a perc 6i controller, i have tried creating a virtual disk combining both and the install goes through, but when the server reboots, it doesnt boot the program, I have tried factory defaulting the controller card and trying the install and it doesnt see the drives at all, i am at a loss, and dont know what to do, to get this freepbx distro installed on this machine, any help would be greatly appreciated
