Use the command in the following table to the perform the Copyback Operation on the
selected Drive.
The copyback feature allows you to copy data from a source drive of a virtual drive to a
destination drive that is not a part of the virtual drive. Copyback is often used to create
or restore a specific physical configuration for a drive group (for example, a specific
arrangement of drive group members on the device I/O buses).
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.
