Chapter 6 HPSS Configuration
HPSS Installation Guide September 2002 315
Release 4.5, Revision 2
6.7.2 Configure the Storage Hierarchies
Storage hierarchy information must be created for each storage hierarchy that is to be supported by
the HPSS system. An HPSS storage hierarchy can be created using the HPSS Storage Hierarchy
window. After the configuration entry is created, it can be viewed, updated or deleted through the
same window.
From the HPSS Health and Status window (shown in Figure 6-1), click on the Admin menu, select
the Configure HPSS option and click on the Storage Hierarchies option. The HPSS Hierarchies
window will be displayed. To create a new hierarchy, click on the “New Hierarchy ...” button.
The Storage Hierarchy Configuration window will be displayed as shown in Figure 6-17. The fields
are displayed with default values for a new storage hierarchy. If the default data is not desired,
change the fields with the desired values. Click on the Add button to create the configuration entry.
To update an existing storage hierarchy, select the Load Existing button on the Storage Hierarchy
Configuration window and select the desired storage hierarchy from the popup list. The window
will be refreshed with the data from the selected storage hierarchy. After modifying the data, click
on the Update button to write the changes to the SFS file. Refer to Section 3.11.2: Changing Storage
Hierarchy Definition (page 80) in the HPSS Management Guide for more guidelines on changing a
storage hierarchy configuration.
