Defining the usage type

The volume set usage type of an SM pubset can be defined with the USAGE operand of the MODIFY-PUBSET-DEFINITION-FILE command:

• STD
  Normal setting. This is the only possible usage type for the control volume set.

• WORK
  Work files can only be stored on volume sets with this usage type.

• HSMS-CONTROLLED
  Volume sets with usage type are required for setting up the S1 level with HSMS. They are only used for this purpose.
