DUMPCLASS: Restricting the specified volume to use a specific dump class

Explanation: DUMPCLASS(class) is the subparameter of the DUMP parameter restricting the specified volume to use a specific dump class. For class, substitute the name of a previously defined dump class for the output copy wanted for the dump.

If class is not specified, the dump volume can be used by any dump class. The FREQUENCY and DAY subparameters of the DUMPCLASS parameter of the DEFINE command determine how often a primary volume is dumped to a given dump class.

Defaults: None.

Note: When you assign a dump volume to a specific dump class, the unit specified by the UNIT parameter of the ADDVOL command is not checked for compatibility with the unit currently defined for the dump class. This allows volumes of multiple unit types to be assigned to the same dump class at the same time. You can switch between using different unit types for the same dump class by redefining the unit for the dump class.
