You can use DFSMSrmm to release DFSMShsm tapes that are requested to be purged by DFSMShsm. You can also specify that DFSMSrmm retain a tape for a few days after its expiration date has been reached. By default, the expiration date protection for DFSMShsm tapes is done by DFSMShsm. DFSMShsm uses 1999/365 as the expiration date for permanent retention. To enable extra days retention for purged DFSMShsm tape volumes, you need to either, depending on the retention method used, use the TVEXTPURGE(EXPIRE(days)) option or set up retention options in the vital record specifications that are used to retain the tape volumes:

• When you use either the EXPDT retention method or the VRSEL retention method, you can specify the number of extra days in OPTION TVEXTPURGE(EXPIRE(days)).
• When you use the VRSEL retention method, you can use OPTION TVEXTPURGE(EXPIRE(0)) and combine an UNTILEXPIRED VRS with an EXTRADAYS VRS:
  1. Ensure that the DFSMSrmm EDGRMMxx parmlib OPTION MAXRETPD operand is set to NOLIMIT to prevent DFSMSrmm from reducing the expiration date used for the DFSMShsm tape volumes. See Defining system options: OPTION for information about the MAXRETPD and TVEXTPURGE operands.
  2. Specify the DFSMSrmm EDGRMMxx parmlib OPTION TVEXTPURGE(EXPIRE) operand.
  3. Define a name vital record specification that specifies the EXTRADAYS retention type and chain the name vital record specification to the vital record specifications used to retain DFSMShsm tape volumes. Also use the COUNT operand to specify the number of days you would like the tape volumes to be retained.
  4. Include the UNTILEXPIRED retention type in the vital record specifications you use to retain DFSMShsm tape volumes and chain these vital record specifications to the name vital record specifications that include the EXTRADAYS retention type.
