DAYS: Specifying migration eligibility of data sets

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.

Note: The management class attribute COMMAND-OR-AUTO-MIGRATE=BOTH must be specified for an SMS-managed data set to be eligible for migration by a VOLUME command.
