Successful change use attribute processing

When the change use attribute function is successful, the following processing occurs:

The use attribute of the volume specified with the VOLUME keyword is changed to the requested value.
The tape volume record is updated with the values specified on the CBRXLCS macro invocation, by the change use attribute installation exit, or both.
If the volume resides in an ATLDS, the category of the volume is also changed in the hardware inventory to the requested value.
If the library supports outboard policy management, the SMS construct names are passed to the library.

Unless the change use attribute installation exit (CBRUXCUA) has been disabled or the installation has indicated that it should not be called, the change use attribute installation exit is invoked for every request to change the use attribute of a volume. See Change use attribute installation exit (CBRUXCUA) for further discussion of the exit.
