DUMP command for DFSMSdss

With the DUMP command, you can dump DASD data to a basic sequential data set, a large format sequential data set or an extended format sequential data set. The storage medium for a basic sequential data set can be a tape or DASD. The storage medium for the large format or extended format sequential data set must be DASD. You can dump data sets, an entire volume, or ranges of tracks.

Note: The FULL keyword for the DUMP command specifies that an entire DASD volume is to be dumped. The TRACKS keyword with the DUMP command specifies ranges of tracks to be dumped.

DFSMSdss offers two ways to process DUMP commands:

Logical processing is data set-oriented, which means it operates against data sets independently of physical device format.
Physical processing can operate against data sets, volumes, and tracks, but is oriented toward moving data at the track-image level.
The processing method is determined by the keywords specified on the command.

DFSMSdss logical dump processing cannot be used to process partitioned data sets containing location-dependent information that does not reside in note lists or in the directory. Furthermore, DFSMSdss cannot be used to dump migrated data sets.

Integrated catalog facility catalogs should not have a high-level qualifier of SYSCTLG because this causes DFSMSdss to treat them as CVOLs.
