Using the DSE parameter with the TAPEMNT command
For a Tape Manager catalog, the DSE and NODSE parameters on the TAPEMNT command can be used to set the Data Security Erase (DSE) attribute of the volume being mounted.
- For read only volume-specific mounts, the parameters are ignored and the DSE setting of the volume is not changed.
- For read-write volume-specific mounts and for scratch mounts, the parameters are respected regardless of the default DSE setting of the pool.
The table below shows the results for various DSE combinations:
Type of mount | TAPEMNT DSE parameter | Pool DSE default setting | Volume DSE setting before TAPEMNT | Volume DSE setting after TAPEMNT |
---|---|---|---|---|
