Logical data set dump

If you specify the DATASET keyword with the DUMP command and do not specify input volumes, DFSMSdss performs a logical data set dump using information in the catalogs to select data sets. For example, the following DUMP command results in a logical data set dump:

DUMP  -
    DATASET(INCLUDE(**)  -
            BY(DSCHA,EQ,YES))  -
    OUTDDNAME(TAPE1)  -
    COMPRESS

If you specify the DATASET keyword with the LOGINDDNAME, LOGINDYNAM, or STORGRP keywords, DFSMSdss performs a logical data set dump by using information in the VTOCs to select data sets. For example, the following DUMP command results in a logical data set dump of all the single volume data sets on volume 338001:

DUMP  -
    DATASET(INCLUDE(**))  -
    LOGINDYNAM(338001)  -
    OUTDDNAME(TAPE)  -
    COMPRESS

The following data sets cannot be processed by logical data set dump or restore operations:

VSAM data sets not cataloged in an integrated catalog facility catalog
Page, swap, and SYS1.STGINDEX data sets
VSAM Volume Data Sets (VVDS)
Partitioned data sets containing location-dependent information that does not reside in note lists or in the directory.

Note: DFSMSdss cannot be used to dump data sets with a volume serial of MIGRAT. The recommended method of dumping migrated data sets is to use ABARS.
