Altering SMS components

You can change the definitions of SMS components, libraries, volumes and drives by selecting the alter option from the Application Selection panels. You can also change the definitions by entering the ALTER line operator against a list of components. This method is more efficient if you want to make multiple changes in one SCDS.

You can also use the MVS SETSMS command to alter some components.

This topic outlines how to alter SMS components. For information on how to alter libraries and drives, see the following:

Altering optical libraries: z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Object Support
Altering tape libraries and drives: z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries

This topic outlines how to alter each SMS component using the component's Application Selection panel.

Note: You must be in storage administrator mode to alter SMS classes. If you are in user mode, you are not authorized to alter SMS classes and libraries. Storage administrator authorization describes storage administrator mode.
