Defining backup volumes to DFSMShsm

If you are using SELECTVOLUME(SPECIFIC) and TAPEDELETION(HSMTAPE), you may want to identify your backup volumes to DFSMShsm. Use the ADDVOL command to identify the volume as a backup volume and to specify the following:

The kind of unit for the volume
Whether the volume is a daily backup volume or a spill volume

The following provides a sample ADDVOL command for adding a DASD daily backup volume on a unit 3390:

ADDVOL BAK001 UNIT(3390) BACKUP(DAILY(5))

This command makes BAK001 a daily backup volume that is used on day five of the backup cycle.

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