Some installations use only data set profiles to protect tape data. They rely on the tape management system to ensure that only valid scratch tapes are used for output. If they use TAPEVOL class without TAPEDSN option in effect, they have RACF exits that change the RACHECK for TAPEVOL class to a RACHECK for the data set being processed. Consequently, they prevent RACDEF in the TAPEVOL class. If your RACDEF exit is used to dummy out the DFSMSdfp RACDEFs that would normally create TAPEVOL profiles, they will also prevent DFSMSrmm from defining TAPEVOL profiles. If this applies to your installation you will have to make changes to your RACF exits before making use of the DFSMSrmm RACF support.

This topic contains examples for converting RACF installation exits.
