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.
