You can use DFSMSrmm with Basic Tape Library Support (BTLS). BTLS is an IBM program offering that provides basic automation support for IBM tape libraries in a non-system-managed library environment. With BTLS, DFSMSrmm does not interact directly with BTLS or with the IBM tape library, so you must update the BTLS catalog to reflect changes to volumes that are managed by DFSMSrmm.

DFSMSrmm adds information to the DFSMSrmm control data set when you define volumes to DFSMSrmm. If you plan to use any of the volumes defined to DFSMSrmm with BTLS, use the access methods services LIBRARY command to define the volumes in the BTLS catalog. Refer to the Basic Tape Library Support Version 1 Release 1 User's Guide and Reference for more information.

If you plan to use DFSMSrmm for volumes managed by BTLS, set up procedures to return scratch volumes to scratch status in the BTLS catalog after DFSMSrmm expiration processing.

Here is a summary of the steps you follow to use BTLS with DFSMSrmm:

1. Use the NAME operand on the VLPOOL parmlib command to identify the BTLS scratch pools to be used.
2. Optionally, if you use data set name and jobname for your volume pools, use the EDG_EXIT100 installation exit to select a pool for new tape data sets.
3. Set up the procedures to return BTLS-managed volumes to scratch status after you run inventory management.
4. Set up the procedures to update BTLS when volumes are added to or removed from the installation media library.
