The following table shows the media options that can be specified with the previous system parameters. The primary and its copy can be directed to different media. These two output media types are synchronized so that if one is shorter than the other and fills up, both are closed and new tapes are mounted and/or new disk archive data sets are allocated.

Other sysparms that are in effect when the respective media option is used are shown in the following table:
