About Hard Drives

The hard drives in the server are hot-pluggable, but this capability depends on how
the hard drives are configured. To hot-plug a drive you must take the drive offline
before you can safely remove it. Taking a drive offline prevents any applications
from accessing it, and removes the logical software links to it.
