Preparing for the Storage Management Subsystem

Before you define and activate an SMS configuration, 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. See Allocating control data sets.
• Define SMS as trusted to RACF. This generally allows the SMS address space to bypass RACF authorization checking and so access the SMS configuration data sets. For more information, refer to Defining SMS as trusted to RACF.
• Modify SYS1.PARMLIB, which contains three members that direct the initialization and activation of SMS. See Modifying the SYS1.PARMLIB data set.
• Establish access to the ISMF Primary Option Menu for Storage Administrators (shown in Figure 1).

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