Diagnostic Routines
TNL SN20-9843 (03-27-87) to 75X0152 or 75X0166
The Diagnostic Routines allow the system user to checkout the system with
minimum action. These routines are used during problem determination to
determine if the system hardware has a problem and provide a Service
Request Number (SRN) for the service organization.
The Diagnostic Routines run more extensive tests on the adapters and
options than the Power-On Self-Test (POST) programs. The checkout
options displayed are from the configuration record on the fixed disk.
If
the
configuration record on the fixed disk does not match the installed features
list, the program displays the TEST OPTION or the DIAGNOSTIC TEST
LIST menu.
When an option is listed in the configuration record but is not sensed by the
Loadable POST programs, the TEST OPTION menu displays. This menu
indicates that either the option has been removed from the system, the
option is failing, the switch settings have been changed, or the option has
been moved to another slot.
When the Loadable POST programs sense an option that is not in the
configuration record, the DIAGNOSTIC TEST LIST menu displays. This
menu indicates an option has been added to the system. When an option is
deleted from the DIAGNOSTIC TEST LIST menu, that option is not tested
until added to the list using the Show and Change Diagnostic Test List
Utility.
To run the Diagnostic Routines:
1. Press Enter after reading the DIAGNOSTIC OPERATING
INSTRUCTIONS.
2. Choose Diagnostic Routines on the FUNCTION SELECTION menu.
3. Choose a checkout option on the DIAGNOSTIC SELECTION menu.
