Conversion to standard options to remove the exits involves deactivating the TAPEVOL class and activating the TAPEDSN option. Use the PROTECTALL option to ensure complete security for tape data. When the TAPEVOL class is inactive, DFSMSrmm does not create TAPEVOL profiles for volumes and cleans up any discrete data set profiles that exist when a tape returns to scratch status. You can rely on DFSMSrmm to validate volumes that are mounted and prevent overwrites, validate 44 character data set names and manage data set and volume expiration.
