The EXPIRE command instructs CA Disk to expire non-VSAM data sets and VSAM clusters. SMS data sets are expired based on DFSMS Management Class attributes if no format-1 EXPDT exists. Non-SMS non-VSAM data sets are expired based on the format-1 EXPDT. The catalog entry expiration date is used for VSAM clusters. The data set expiration date is compared against the current date, or the date specified in the DATE= parameter, to determine if a data set is expired. If a data set satisfies DSCL selection and is determined to be expired by CA Disk, it is deleted from DASD.
