Defining additional storage groups

z/OS DFSMSdfp Storage Administration
SC23-6860-01

You can copy existing storage groups and modify them to create new storage groups by using the COPY line operator, which is explained in Copying SMS components.

When you copy either a pool or VIO storage group within an SCDS, all of the system status values and system names for automatic processing are copied. When you copy either a pool or VIO storage group from one SCDS to a different SCDS, all of the system status values default to ENABLE rather than to the system status values of the source storage group. Also, the Migrate System Name, Backup System Name, and Dump System Name fields are set to blank.

Whenever you copy an object storage group within an SCDS, you must modify the qualifier to ensure that the new object storage group has a unique qualifier for the connected system. All qualifiers within an system must be unique. Specify Y for the Perform Alter attribute on the Copy Entry panel to display the Object Storage Group Alter panel. Modify the qualifier and issue an END command to save the new qualifier.

Whenever you copy an object storage group from one SCDS into a different SCDS, the qualifier must be unique within the target SCDS. If necessary, alter the qualifier in the same manner as required for copying an object storage group within an SCDS.

The system status values of object and object backup storage groups are retained when copying within an SCDS. Object and object backup storage groups can be enabled by and connected to more than one system. Specify Y for the Perform Alter attribute on the Copy Entry panel, and Y for the Alter SMS Storage Group Status attribute on either the Object Storage Group Alter panel or Object Backup Storage Group Alter panel to display the system statuses for modification.
