I'm nervous to trust the hotswap features and camcontrol to set things up properly, but I guess I could try it. When I first set the system up before I put data on the array I tried the hotswap functionality and drives wouldn't always re-attach when reinserted, even if I fiddled with camcontrol, but I can't remember exactly what I did then.
