Setting the scope of automatic assignments

When you select the A option to "Create a Recommended System Layout" from the Modify System Layout Options panel, the panel shown in Figure 1 is displayed. This option causes the dialog to automatically assign the target and DLIB data sets in the configuration to physical volumes. The dialog does not automatically assign any SMS-managed data sets in the configuration.

Figure 1. Panel: Modify system layout options

 CPPP625B  --------- Automatic Data Set Assignment ( MD053718 ) ----------
 OPTION ==>


     A - ALL      Assign all target and DLIB data sets in the configuration
                  to physical volumes automatically.  This option creates a
                  recommended system layout.

     N - NEW      Add new data sets to an existing configuration.  This
                  option automatically assigns new data sets, but preserves
                  the placement of previously-assigned data sets in your
                  saved configuration.

     P - PARTIAL  Assign new data sets and reassign some existing data sets
                  to physical volumes.  This option automatically assigns
                  all new data sets to physical volumes, as well as data
                  sets from selected volumes in the saved configuration.


 Enter EITHER a default device type OR a model volume below:

 Default Device Type ==> 3390-9     (For example, 3390-9)
  Model after Volume ==>            (For example, ZOSRES)

You can control the scope of the dialog's automatic assignments by selecting one of the following settings in the Modify System Layout Options panel:

ALL: This setting causes all target and DLIB data sets in the configuration to be automatically assigned to physical volumes.
NEW: This setting causes data sets that are new to the configuration to be automatically assigned to physical volumes, but preserves the assignment of data sets that already exist on volumes in the saved configuration.
PARTIAL: This setting causes all new data sets in the configuration to be automatically assigned to physical volumes, and also allows you to exclude particular volumes from the saved configuration, freeing their data sets for reassignment.

To see which new data sets will be assigned automatically, you can use the dialog's View and Change Facility to create a list of data sets that have the attribute "New Data Set." For more information, see Viewing and changing data sets.

In some cases, not every setting on this panel is selectable. For example, if you are not including a saved configuration in the new configuration, the only selectable setting on this panel is All.
