Troubleshooting Aids
There are many troubleshooting "aids" available to help the investigator locate a failed FRU:
Maintenance Processor
The most useful is the Error Log indications as read using the maintenance processor (MP). Also,
the MP ps command and others enables the user to interrogate the server quickly.
ODE Diagnostics
The Offline Diagnostic Environment (ODE) is useful for troubleshooting a system that is running
without an operating system or cannot be tested using the online tools. This offline environment
is also useful for some types of testing in which it is not desirable to have to boot the system first.
The CE has the choice between a pure command line interface or a menu-driven interface.-
Support Tools Manager (STM/EIT) is useful for: > Testing the system while it is online (OS is
running). > Exercising the system to uncover the cause of intermittent problems. > Testing interface
cards and peripheral devices. > Looking at system logs to get detail about suspected problems.
> Obtaining hardware-related information, using Information tools. ->Other functionality, such
as downloading firmware to devices.
