ALLDATA applies to full and data set dump operations.

dsn

Specifies the fully qualified name of a data set whose data set organization is PS, PSU, PO, POU, or null, for which all allocated space is to be dumped.

* (asterisk)

Specifies that all allocated space is to be dumped for the following data sets:

All sequential and partitioned data sets that are not empty, and
Data sets whose data set organization is null and are not empty. (The last used block pointer in the data set's volume table of contents (VTOC) entry is not zero.)

Note:

Data beyond the last used block pointer is not retained when ALLDATA or ALLEXCP is specified for an extended-format sequential data set during a logical dump operation. During a subsequent restore operation, the target data set is allocated with the same amount of space as the source data set.
All of the allocated space is always dumped for a physical dump of PDSE and HFS data sets.
For a logical dump of PDSE or HFS data sets, the following conditions are true:
- If DFSMSdss can determine the amount of used space, DFSMSdss dumps only the used space, regardless of the ALLDATA keyword.
- If you specify ALLDATA, DFSMSdss remembers the amount of allocated space. During a subsequent restore operation, DFSMSdss will allocate the target data set with the same amount of space as the source data set.
- If DFSMSdss cannot determine the amount of used space, it assumes that the used space is equal to the allocated space. DFSMSdss then dumps all of the allocated space.
