Yes, the RAIDing is completely transparent to the OS. You don't even
have to reboot the machine if the disks are hot-swappable. Just pull the
dead one out, install the new one, and the controller will bring it up
to speed. RAID-1 is much faster to rebuild than RAID-5 (just a casual
observation; I'm not sure if that's a hard-and-fast rule).

you're welcome.
