If the logical library partition is configured for advanced control path
failover functionality, the managing APF device driver will select a
redundant path and request that the library enable the redundant path
as the active control path. In this case, the current path is disabled and
the new path is enabled, resulting in the existing LUN 1 for the current
active path to disappear and a LUN 1 activating the selected redundant
device.
