We recommend retaining the default low-level qualifiers that are supplied for the installation libraries. However, if you need to change any of them (for example, to conform to site-specific naming conventions), you can do so by editing them in member USSSNAME of high_level_qualifier.HOME.DATA. You can see a list of the qualifiers in Default Low-Level Qualifiers.
Caution: If
you change any low-level qualifiers and do not reflect those changes
exactly in USSSNAME, you will experience problems with the server
installation and operation.
After you have finished changing any names, continue with Step 5. Run ISETUP.
