Jack,
I've never heard of a warring message like that before. Where did you receive that message, was it through the OS or RAID Shield? Perhaps this is something new in Snow Leopard.
I suggest you give our tech support a call, so they can check some things with your setup over the phone. I wish I could be of more assistance, but I've never need that warring before.
