Remove Raid Disks from one computer, put them into another?

Just a question, if i have 2 identical dell servers, one of them sitting around waiting for disaster to occur... can i yank the whole raid array from one server and put it in the other one if the motherboard on the production server died? or is there some other configuration going on that would prevent this.

I've never actually tried that, but if the controllers are identical, my take is it should work.  If this is a critical server, I would try it out on a weekend and see if it pans out.

if they are identical it should work. Only thing I would worry about is that if the Array will stay intact after removing the card (if it's not onboard)

I would agree with Callandor - try it out during a down time to know what your looking at should you have to do it in a real emergency.
if they are both perc 3di controllers you can probably do this, as long as the firmware on both controllers is the same.

Actually if you can do this depends on where the array configuration is stored. On Compaq servers it stored on all the disks, so move them to another Compaq server with a RAID controller it will pick up the information off the disks. Now if Dell stores the information on the RAID controller its self, some raid systems work this way, if you move the disks you may end up losing the information on them, that is unless you back up the RAID information off the RAID controller, and transfer it to the other controller. If I where you, I’d check with Dell tech support and find out how their RAID system works before I’d start experimenting.  
It depends on whether you are using an adaptec based controller such as the perc3di or an LSI based controller such as the perc4di....if using an adaptec, you can do it, if using an LSI, you MIGHT be able to do it...the main thing it depends on is that both controllers have the same firmware.
jeff
oh, the adaptec controllers store array info specifically on the disks, the LSI controllers store it on the controller AND the disks.
lol the accepted answer kinda looks like a combo of the 1st 2 comments
