DFSMSrmm can provide enhanced management functions for the tape volumes that DFSMShsm uses for each of its tape functions. The way the two products work together depends on how you are using each of them in your installation. Run DFSMSrmm with DFSMShsm to enhance the management of the volumes DFSMShsm uses. For example, DFSMSrmm can manage the movement of tapes that must be sent out of the library for disaster recovery. Using DFSMSrmm and DFSMShsm together, you can use the scratch tape pool rather than a DFSMShsm tape pool.

DFSMSrmm provides the EDGTVEXT, and EDGDFHSM programming interfaces that can be used by products like DFSMShsm, OAM, and Tivoli Storage Manager. Use these programming interfaces for DFSMSrmm tape management so that you can maintain correct volume status. DFSMSrmm treats DFSMShsm like any other tape volume user and retains DFSMShsm volumes based on vital record specifications and retention period. DFSMShsm automatically calls EDGTVEXT so you do not need to perform any special set up for DFSMShsm to communicate with DFSMSrmm. You can use the TVEXTPURGE parmlib option in the DFSMSrmm EDGRMMxx parmlib member to control the action DFSMSrmm takes when DFSMShsm calls EDGTVEXT. A benefit of this interaction is that DFSMSrmm can prevent DFSMShsm from overwriting its own control data set backup, automatic dump, ABARS, and copies of backup or migration tapes. Although DFSMShsm checks its own migration and its own backup tapes, DFSMSrmm checks them as well.
