ALTERNATEVOLUMES: Specifying which volumes to copy

Explanation: ALTERNATEVOLUMES(avol1,...avoln) is an optional parameter that defines which output volumes are to be used in place of scratch tapes. These tape volumes are indicated by their volume serial numbers avol. If specified, the number of entries in ORIGINALVOLUMES and ALTERNATEVOLUMES must match. The TAPECOPY function will maintain a one-for-one correspondence between the two sets of entries. The alternate tape volumes are made even though the original volumes may not be marked as full.

When considering 3480, 3480X, and 3490 volumes, the original volumes and the alternate volumes must use the same recording technology. If the original volume is written using the Improved Data Recording Capability (IDRC) of the 3480X, then the alternate volumes must be written using the IDRC. The reverse is true as well.

For 3490 volumes or 3590-1 volumes, the original volumes and alternate volumes must use the same media type. If the original volume is written using a standard capacity cartridge, then the alternate volume must be written with a standard capacity cartridge (an enhanced capacity cartridge cannot be used). The reverse is true as well.

Defaults: None.
