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 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.

TEST OPTION
  When an option is listed in the configuration record, but is not sensed by the Loadable POST programs, the TEST OPTION menu is displayed. This menu indicates 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.

DIAGNOSTIC TEST LIST
   When the Loadable POST programs sense an option that is not in the configuration record, the DIAGNOSTIC TEST LIST menu is displayed. This menu indicates an option has been added to the system. When an option is deleted from the DIAGNOSTICS 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. 
     Note: An "*" (asterisk) by the ID number shows that the test has been run.
