In addition to the RESTART and conflict resolution data sets, DFSMShsm dynamically allocates the following data sets during aggregate recovery processing. These data sets are used while aggregate recovery is executing and are dynamically deallocated before completion of aggregate recovery 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, and if they are SMS-managed, your ACS routine must assign them to a storage group that contains storage-type volumes.) 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.
The SYSIN data set is used to pass RESTORE parameters to DFSMSdss. The SYSIN data set name is: authid.SYSIN.agname.Thhmmss
The FILTER data set is used to pass a list of data set names to DFSMSdss. The FILTER data set name is: authid.FILTER.agname.Thhmmss
