Data sets that DFSMShsm dynamically allocates during aggregate backup processing

DFSMShsm dynamically allocates the following data sets (SYSIN, FILTER, and authorization-checking) during aggregate backup processing. These data sets are used while aggregate backup is executing and are dynamically deallocated before completion of aggregate backup processing. These data sets are allocated with a unit type of SYSALLDA. (If they are non-SMS-managed, you must have at least one STORAGE- or PUBLIC-type device online to use the system.) You need to be aware of these data set names so that the high-level qualifiers used by ABARS can be defined to the system. You may want to modify your ACS filters to direct allocation of these data sets to specific volumes.
