Using same hot spare for both mirrored drives and raid 5

Hello, this may seem like a dumb question but I was wondering if you can use the same hot spare for both a set of mirrored drives (OS) and raid 5 (Data) in the same server?

Jeremy:

Though I haven't played around with a Smart Array in a few months, I believe you can assign a hot spare to multiple arrays... as long as the hot spare is big enough to handle the failure.

I.E. If you have 72GB drives for your mirrored OS and 146's for your RAID5 data, you need a 146GB drive to cover both array. You can't use a 72, for obvious reason.

Jeremy,

You can assign a drive as a universal hot spare by designating it as the hot spare for each array.
