Abstract
DFSMSrmm is an IBM® z/OS® feature that is a fully functioning tape management system to manage your removable media. In the last decade there have been many enhancements to DFSMSrmm and this IBM Redbooks® publication is intended to help you configure and utilize the newer functions and features now available. Discussion of the new features is included along with usage cases. There are also some hints and tips of various common DFSMSrmm problems and useful configuration and reporting JCL.
This publication is intended as a supplement to the IBM Redbooks publication DFSMSrmm Primer (SG24-5983-04) which is still the recommended starting point for any users new to DFSMSrmm.
