The installed tape management system controls the expiration of the Virtual Volumes. The Virtual Volumes are under the tape retention control that the application requested in their JCL or dynamic allocation request. The Virtual Volumes can also be under the retention that the tape management system specified in the retention rules.
When Virtual Volumes meet the required retention control requirements, the tape management system expires and scratches the affected tapes. Virtual Volume expirations must be communicated to CA Vtape so that its control data sets can be updated with the change in status.
