Diagnostic Routines
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 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. An
*
(asterisk) by the ID number shows that the test has
been run.
