EXPIREDDATASETS: Specifying whether to scratch data sets with expired expiration dates

Explanation: EXPIREDDATASETS(SCRATCH | NOSCRATCH) is an optional parameter specifying whether or not DFSMShsm should scratch data sets having explicit expiration dates when the date has passed (data set has expired). SMS-managed data sets not having explicit expiration dates are expired when they have met their management class expiration criteria.

Note: Explicit expiration dates can be set by JCL, utility parameters, Data Class Expiration parameters, or Data Class Retention parameters. The explicit expiration date for a data set can be found in the data set's VTOC entry.

SCRATCH specifies that DFSMShsm scratch data sets that have an expired expiration date when it performs space management and migration cleanup.

NOSCRATCH specifies that DFSMShsm ignore the expiration date. DFSMShsm processes the data set as if the expiration date has not been reached.

SMS relationship: Parameter applies in some instances to SMS-managed DASD volumes or data sets.

SETSYS default: None.

DFSMShsm default: If you do not specify this parameter on any SETSYS command, the DFSMShsm default is not to scratch the expired data sets.
