SELECT (ALTERNATEVOLUME and NOALTERNATEVOLUME): Listing tape volumes that have alternate tape volumes

Explanation: ALTERNATEVOLUME and NOALTERNATEVOLUME are mutually exclusive optional subparameters used with LIST TAPETABLEOFCONTENTS when volser is not specified.

ALTERNATEVOLUME
lists only those tape volumes that are marked full or partially full and that have alternate tape volumes. This list provides you with the capability to identify the full or partially full backup and migration tape volumes that have alternate tapes. In a duplex tape environment, you want to keep those alternate tapes in the library because they can be extended. In a nonduplex tape environment, you may want to EJECT those alternate tapes from the library or initially not put them in the library.
NOALTERNATEVOLUME
lists only those tape volumes that are marked full or partially full and have neither alternate tape volumes nor DISASTERALTERNATEVOLUMES.

Defaults: None.
