You should have installed DFSMSrmm, along with the other DFSMS components, using SMP/E. Refer to the z/OS Program Directory you received with the product tape for complete installation instructions.

If you have multiple z/OS images or systems on which you want DFSMSrmm to manage tape processing, there are some basic decisions you must make about how to implement DFSMSrmm. If the systems have access to shared DASD, you can set up one DFSMSrmm control data set and share it among your systems. Systems in a sysplex are best managed using a single control data set. When you have multiple sysplexes and have shared DASD between them, you can choose to have a single control data set to be shared or one control data set per sysplex. If you do not have shared DASD on which to place a control data set for all systems to share, consider using DFSMSrmm client server support for z/OS to enable a single control data set to be used. See Setting up DFSMSrmm client and server systems for additional information.

Recommendation: After you have installed DFSMSrmm using SMP/E, IPL your system without performing any DFSMSrmm implementation tasks and have DFSMSrmm take no part in removable media management. This is especially helpful if you are running another tape management product in production.

See Evaluating removable media management needs for a checklist to help you plan for implementing DFSMSrmm.
