Defining dump volumes to DFSMShsm

If you are using SELECTVOLUME(SPECIFIC) and TAPEDELETION(HSMTAPE), you will want to identify your dump volumes to DFSMShsm. Use the ADDVOL command to identify the volume as a dump volume and to specify the kind of unit for the volume and the dump class to which the volume belongs. A sample ADDVOL command for adding a dump volume might be:

ADDVOL DMP001 UNIT(3490) DUMP(DUMPCLASS(ONEWEEK))

Figure 1 lists the complete set of DFSMShsm commands that the example system uses to control automatic dump processing for SMS-managed storage.
