Volume Report Utility

The function of the Volume Report utility is to produce a listing of the physical location for volumes residing in an LSM. This utility is used primarily for informational purposes and provides history and usage statistics on specific library volumes.

The Volume Report utility program functions as a stand-alone process in batch mode and does not require that the HSC be operational in order to execute. If the HSC is operational, Volume Report can extract CDS and VOLATTR information from the active HSC.

In addition to the reporting capability, the utility can produce a ‘‘flat file’’ which may be used as a data source for manipulating the data for user-defined reports with other software products.

Note: It is recommended that a 2 megabyte region size be used when running the Volume Report utility.

A report may be sorted or unsorted. When the SORT option is specified, volume data can be sorted by:

•volume serial numbers

•location of volumes

•select count (usage) of volumes

•date volumes were inserted into the library control data set

•last date volumes were selected.

Sorting may be done in ascending or descending order.

•The report sorted by volume serial number is useful when a listing of library information is needed in ascending VOLSER sequence.

•The report sorted by location can be utilized for either the mass transfer of volumes or assessing the potential impact of a component failure. With this information, the installation can avoid jobs which access volumes within failed components.

•The report sorted by usage lists volumes by selection count. This report is useful for either ejecting low use volumes or replicating information on high use volumes.

The utility output may include a variety of information, depending upon the user-specified parameters. For example, volume information can be specifically included or excluded from a report based on:

•scratch status

•errant status

•external label status

•selected status.

Specifying of report parameters can range from the ACS or LSM level to as specific as a single volume serial number or list of volume serial numbers. Whenever a report is generated using library element parameters (i.e., LSM and/or ACS), the Volume Report utility may also output messages identifying empty but allocated cells.
