For consistency reasons, pubsets should always be saved and restored in their entirety.
FDDRL can guarantee the completeness and consistency if you save a pubset using DUMP-PUBSET and the SAVE-ENTITY=*DISK-SET operand and restore it using the RELOAD-PUBSET statement.
If a pubset was saved using DUMP-PUBSET and SAVE-ENTITY=*SINGLE-DISK or each individual pubset was saved using DUMP-DISK, when you restore this pubset you must restore each individual disk with RELOAD-DISK. Here you yourself must ensure that you restore the pubset completely and consistently (i.e. of the basis of a uniform save status).
The tapes which belong to a save can be ascertained from the save log, from FDDRL job variables or on the basis of the file name using the tape management system MAREN.
Pubsets can only be restored when they have been exported with EXCAT.
