Secure data erase z/OS DFSMS OAM Planning, Installation, and Storage Administration Guide for Tape Libraries SC23-6867-00 |

The secure data erase support guarantees that logical volume data that has expired in the VTS cannot be recovered by any reasonable means once the physical volume where the data resided has been reclaimed. The secure data erasure function is enabled on a physical volume pool basis when a non-zero value is specified for the secure data erase reclaim policy. For additional information on using this support, see IBM TotalStorage Enterprise Automated Tape Library (3494) Operator’s Guide. |
