This topic describes how to use the DFSMSrmm ISPF dialog to define resource information to the DFSMSrmm control data set so that DFSMSrmm can manage those resources. You can define information about shelf locations, volumes, owners, software products, and data sets to DFSMSrmm. Once a volume is defined, DFSMSrmm automatically records information about it, as well as information about any data sets residing on the volume. DFSMSrmm records this information each time a data set is opened and closed.

The ISPF dialog uses DFSMSrmm TSO subcommands to add and update resources. To process the TSO subcommands, you need to be authorized. See z/OS DFSMSrmm Implementation and Customization Guide for more details about authorizing DFSMSrmm users and ensuring security.
