Before you define and activate an SMS configuration, you need to perform the following preparatory steps:

• Allocate control data sets to contain your SMS configuration and to permit the systems in your complex to communicate with each other.
• Modify SYS1.PARMLIB, which contains three members that direct the initialization and activation of SMS.
• Establish access to the ISMF Primary Option Menu for Storage Administrators (shown in z/OS DFSMSdfp Storage Administration).

This topic describes how to perform these preliminary steps so that you can begin defining a base configuration for an SMS configuration.
