If it only has a single plex, you're in trouble. In that case, you need your recovery company to get an image of the failed disk. Then you should put it on a similar disk, create a configuration entry and perform some other incantations, and you should be up and running again. If you have two or more plexes, you shouldn't need to do any of this. Greg -- When replying to this message, please copy the original recipients.
