DISASTERALTERNATEVOLUMES: Identifying the alternate volume as the disaster alternate volume

Explanation: DISASTERALTERNATEVOLUMES is an optional parameter that causes each alternate volume to be flagged as a disaster alternate volume. If DISASTERALTERNATEVOLUMES is specified, a flag is set for each ML2 tape and backup tape that has an alternate volume. The designation of "disaster alternate volume" helps distinguish between alternate volumes initially present at the recovery site and alternate volumes created later at the recovery site. If DISASTERALTERNATEVOLUMES is not specified, each original volume is replaced by its alternate volume in any of the DFSMShsm volume and data set records that refer to it. For more information on the use of disaster alternate volumes, refer to the Making disaster backup copies of DFSMShsm-owned tape volumes.

Defaults: None.
