Account Inheritance. A flag that indicates whether or not newly created files and directories should
automatically inherit the account index used by their parent directory. The default value is OFF. It is only
used if Account Validation has been enabled and Site- style accounting has been selected. If this flag is
disabled, new files and directories have the user’s current session account index applied to them.

13.2.2.1. Generating an Accounting Report
The HPSS Accounting Report tool accumulates accounting information from metadata and generates a
report file. The accounting report will include:
• Total file accesses, total number of files, and total space used per account per class of service.
• Total file accesses and amount of data transferred per account per class of service per storage
class.
The accounting report represents a blurred snapshot of the system storage usage as it existed during the
accounting run. By “blurred snapshot” we mean that the accounting information is gathered while the
system runs, so the accounting data is changing underneath it, and it may not represent what would be
collected if no users were active during the accounting process. Accounting information is maintained
per storage subsystem and the accounting reports summarize information for that storage subsystem.
Before creating an accounting report, you must create and fully configure an Accounting Policy. The
initial Accounting Policy should be set up before any files are created in the HPSS system. Except for the
Accounting Style, the Accounting Policy fields can be updated any time after the initial setup.
There are two ways to generate an accounting report: from the Subsystems window or from the
Accounting Status window. For each method, begin by selecting the Accounting Report menu item from
the Operations menu on the HPSS Health and Status window. This will bring up the Subsystems
window. Click on the storage subsystem for which an accounting report will be generated. This will
highlight the Accounting Status and Start Accounting buttons.
To create an accounting report, choose either of these methods:
● On the Subsystems window, click the Start Accounting button. The accounting report should run
quickly and a completion status will appear at the bottom of the Subsystems window.
● Bring up the Accounting Status window by clicking on the Accounting Status button on the
Subsystems window. On the Accounting Status window, click the Start Accounting button. The
accounting report should run quickly and a completion status will appear at the bottom of the
Accounting Status window.
For either method, the Accounting Status window will display the overall statistics from the last
accounting run.
