Not sure how it'll work with FreeBSD as I haven't lost drives in any PERC2 FreeBSD boxes. There were PERC2's with at least a couple different chipsets. There may be software RAID utilities available that you can use (like asr-utils as an example). > What would happen if I pull the drive out since its hotswappable?

Not something I'd ever do during peak hours. The absolute safest way with any OS, in my experience, would be to shut it down, swap the drive, power up and get into the RAID controller's BIOS and rebuild from there (don't have to wait for the rebuild to complete successfully), then boot the server back up.=20 Probably only 10 minutes of downtime.
