DFSMShsm reporting

Because it performs so many functions, DFSMShsm typically is the largest user of CPU on a system.

For example, DFSMShsm acts as a data mover, performs extent reduction, and removes extents.

The MainView SRM DFSMShsm features analyze historical data that is derived from DFSMShsm log files and DFSMShsm control data sets. Using the DFSMShsm reports can help you meet your service-level agreements (SLAs). You can use the reports to determine how effectively your data is being managed and to identify ways to save CPU cycles. For example, you can identify GDG generations that will soon be deleted and save CPU cycles by not migrating those generations.

You can select and organize the information in DFSMShsm views in the following ways, depending on the view:

  • By time range (hours or days) using the TIME command

  • By using the HSMDAYS keyword to override the TIME command to align the reported days with the DFSMShsm cycle days

  • By management class (using the SETSRM MGMTCLASS parameter or providing it in the data-entry panel)

  • By host ID (using SETSRM HOSTID parameter or providing it in the data-entry panel)

  • By data set name (using the SETSRM DSN parameter or providing a data set name or name mask on a data-entry panel)

  • By system ID (using the SETSRM SYSID parameter or providing a system ID on a data-entry panel)

  • By volume (using the SETSRM VOLUME parameter or providing a volume serial number on a data-entry panel)

  • By form (using the FORM command and a form name)

The online Help for each view lists the available forms.

On most views, you can enter DFSMShsm commands (such as HMIGRATE and HRECALL) for fast, flexible access to DFSMShsm operations using MCDS, BCDS, OCDS, and DFSMShsm log files.


To enable DFSMShsm reporting features, you must have log Y and log X DD statements in your DFSMShsm startup procedure. For more information, see Customizing MainView SRM products and Reference for MainView SRM Reporting.

For more information about the DFSMShsm environment setup requirements and output management, see Reference for MainView SRM Reporting.
