First off, most of the people in the FreeBSD lists can get fairly upset when they see people cross-posting to more than one list at a time. Generally, if you ask a question, it is pretty much list etiquette to ask one list, and be redirected to another if necessary. I have removed hardware from this reply. Technically speaking, this isn't really FreeBSD related, but I'll take a crack at it. Manufacturers of RAID disk arrays generally have their own disk configuration techniques. I have found that moving disks from one RAID controller to another does not work, and the array has to be re-created. I don't know if this is standard across the board, but my experience tells me that it may be the case. You'd be better off cloning the RAID array, say to perhaps a single IDE disk, migrating the disks to the new controller and creating the array on that controller, and if the machine does not come back up, clone back from the IDE backup onto the new array.
