The dump functions of DFSMShsm support all data sets supported by the physical dump processes of DFSMSdss. For more information, refer to z/OS DFSMSdss Storage Administration.

If the data set organization field (DSORG) of the data set VTOC entry indicates PS, PO, DA, or VS access methods, DFSMShsm initiates management of the data set. Be aware that some application program processes are dependent on how the PS and DA data sets are blocked or accessed. Applications that do not use standard access methods for data sets may fail after the data has been processed by DFSMShsm. An example of this would be data sets that are created for IMS™ databases and accessed with the IMS overflow sequential access method (OSAM).
