In HSMS V10.0A and higher, the global parameter SAVE-FILE-PROCESSING can be used to define the processing mode for save files at storage level S1, on shared disk, and on Net-Storage: *HSMS-V9-COMPATIBLE or *HSMS-V10-COMPATIBLE.
Save files generated in processing mode *HSMS-V9-COMPATIBLE can be processed without restriction with HSMS versions lower than V10.0A. However, save files generated in processing mode *HSMS-V10-COMPATIBLE can only be processed with HSMS versions lower than V10.0A if the files are on tape or private disk. The reason for this is that save files on shared disk and Net-Storage which were created in *HSMS-V10-COMPATIBLE mode have a different name structure than the files created in *HSMS-V9-COMPATIBLE mode.
*HSMS-V9-COMPATIBLE mode is set by default. However, the full functionality of HSMS is not available in this mode. If you want to use the full functionality of HSMS, you must explicitly specify *HSMS-V10-COMPATIBLE mode.
The table below provides an overview of the functions available depending on the setting of the SAVE-FILE-PROCESSING parameter:
Functionality | SAVE-FILE-PROCESSING | |
*HSMS-V9-COMPATIBLE | *HSMS-V10-COMPATIBLE | |
Save file names independent of the storage location (in the case of shared disk and Net-Storage) | - | + |
Use of S1-SM pubsets | - | + |
Distributing save files to multiple volume sets within an S1-SM pubset | - | + |
Sequence number in save file names (when using S1-SM pubsets) | - | + |
Continuing save files created with HSMS versions < V10.0 on shared disk or Net-Storage | + | - |
Read access to save files created with HSMS versions < V10.0 | + | + |
Access with HSMS versions < V10.0 to shared files on public disk or Net-Storage which were created with HSMS V10.0 | + | - |
Distribution of the save files to multiple volume sets in an SM environment when storage level S1 is defined as *ALL-HSMS-CONTROLLED | - | + |
+ | Function is available |
- | Function is not available |
