I have an old Dell PE2950. The system will not pass POST; it hangs at an HP Smart Array P212 controller - it shows initializing, sees the memory on the controller and just stops. I have replaced the motherboard on the dell and the riser card. I have ordered two new controller cards and both exhibit the same issue. If i stick the controller into another dell server I have the same issue occurs. The HP controller is for and HP storageworks autoloader (tape backup). If i remove the HP card the dell boots just fine (windows installed on raid array on dell perc controller). I cant get into the BIOS or the boot menu when the HP controller is installed because it hangs after initializing.
There is a little history. The drives in this computer are from another server. There are two PE2950's, one is the backup server and one is a DC. The DC crashed and for time considerations we swapped the hard drives between servers - had to to some array configurations but all went well. After we got the replacement parts we put them in the backup server and booted - only it will not boot with the HP card installed
