Sounds good, but I don't see a way to do that. As far as I can tell, a "spares group" isn't a thing that exists in its own right - it's a property of an array, and arrays with a matching "spares group" property will share spare disks if necessary and possible. I'd be pleased to be wrong, let me know if I've misunderstood. Thanks - -- Joe
