SETSYS TAPESECURITY(EXPIRATION)

If you use a system scratch tape pool for DFSMShsm tapes, you need a way to manage tapes protected with expiration dates that are set by DFSMShsm. To help you manage this situation, DFSMSrmm lets you automate the responses to expiration date protection messages for scratch pool tape volumes. Use the parmlib member VLPOOL command to set up this automation. Set the VLPOOL EXPDTCHECK operand to EXPDTCHECK(N) as described in Defining pools: VLPOOL. DFSMSrmm automatically lets your users reuse the volumes in the pool without operator intervention and without creating data integrity exposures.

If you use a DFSMShsm-managed tape pool, DFSMShsm validates and overrides expiration dates on its emptied, previously used tapes.
