Ok, that is very good news. The controller is a PERC 3/Di, and it uses the aac driver. When you say the controller probes the disks, do you mean, as the controller BIOS is doing coming up during POST it just does it and asks me on the POST screen, or do you mean I need to hit ctrl-A and go into the controller bios, and at some point _in there_ it will ask me ? If the answer is "you have to hit ctrl-a and go into the bios", I am curious as to what would happen if I didn't - and I just let it boot ? thanks! > > > > > > > Hello, > > > > I have machine X that has failed, and I have an identical > > machine Y that has > > not failed - both machines have identical RAID hardware - a > > Dell PERC 3. > > > > I have not touched, configured, or even booted machine Y. > > > > What will happen if, while both machines are off, I take all > > disks from > > machine X and put them into machine Y, and then turn machine Y on ? > > > > The configuration on machine X is four disks, that are > > combined into two > > mirrored volumes. > > > > As you can guess, I basically just want to move the disks and > > preserve my > > system completely - I am very worried about losing data, or > > having the new > > raid controller re-initialize things or otherwise trash things. > > > > Any advice appreciated. > >What kind of PERC is it, specifically?
