For anyone else that may come across this thread, the main issue when you don't know your array positions is the parity drives. Simply put all your drives in the array, position doesn't matter. Then you will have one or two drives which say they need formatting, these are your parity drives, record the drives, stop the array, go to tools, new config, select all to keep settings, then go back to your array setup and set those drives as the parity.
