I guess you need not just the spare hardware (which is possible if you have more than one server to start with and two can come out at the same time) but the maintenance window to a) pop the disk and then b) rebuild the RAID afterwards. At least, I'm assuming that the RAID-1 is just going to treat the disk you pop back in as of unknown status and re-mirror it. Good thoughts, thanks, --Alex
