I have hot swap drives and controllers, but have never actually used the hot swap capability. What is the procedure for doing so? Do I need to warn Linux that I'm about to pull a drive out? Should I do anything after I put a drive back in? Does it make a difference whether the drive is part of a RAID set?

The drives are generally RAIDed, but not always. Any RAID sets are managed by Linux, rather than the controller. The machines are running Fedora and CentOS.
