Altering storage groups

As the needs of your installation change, you might need to modify storage groups. To modify a storage group, go to the Storage Group Application Selection panel, and specify the name of the SCDS containing the storage group that you want to modify. Specify the storage group name and select option 3, ALTER. ISMF displays the Storage Group Alter panel.

You can also use the SETSMS command to change the SMS status of storage groups.

Restriction: Any SMS status that is changed using the SETSMS command is overridden by the MVS status if a new configuration is activated. See z/OS MVS System Commands for more information on the SETSMS command.
