Typically, when a drive fails or is expected to fail, the data is rebuilt on a hot spare. The
failed drive is replaced with a new disk. Then the data is copied from the hot spare to
the new drive, and the hot spare reverts from a rebuild drive to its original hot spare
status. The copyback operation runs as a background activity, and the virtual drive is
still available online to the host.
