In SIMULATION mode (OPERATIONAL-MODUS=*SIMULATION), all HSMS statements are permitted but action statements are only simulated. This means that, although the syntax of HSMS statements is checked and the requests are generated and written to the request file.
The server tasks perform no more than a kind of pseudo processing. The requests are set to the COMPLETED state but no ARCHIVE actions are initiated, i.e. no data manipulation takes place. This mode is useful for familiarizing oneself with the functions of the various action statements without actually accessing user files.
Extreme caution should be exercised when using the HSMS statement MODIFY-ARCHIVE in simulation mode since certain activities are not just simulated but are actually performed (e.g. sharing backups with //MODIFY-ARCHIVE SAVE-FILES= *DELETE).
Action statements from active nodes are rejected when HSMS is running in simulation mode.
