Explanation: DAYS(0) is an optional parameter supplied for an SMS volume that allows the movement of all data sets for which automatic space management is supported. The data set’s management class attribute value for PRIMARY-DAYS-NON-USAGE need not have been met. For SMS-managed volumes, the value specified for the DAYS subparameter must be zero. If a value other than zero is specified or if no value is specified, the command fails, and a message indicating the error is issued.
Defaults: None.
