Disabling and enabling primary and alternative paths

When you load the lin_tape device driver with the alternate_pathing parameter to be ON, by default, all the available paths for a physical device are enabled.

If it is necessary to disable a path and not run path failover (for example, because of maintenance), run commands to disable and then later enable the primary and alternative paths.

The commands to enable and disable primary and alternative paths are tape diagnostic and utility functions.
