Error symptoms
You can use the error symptom tables to find solutions to problems that have
definite symptoms.
If you cannot find the problem in the error symptom charts, go to “General
checkout” on page 37 to test the server.
If you have just added new software or a new option and the server is not working,
do the following before using the error symptom charts:
v
Remove the software or device that you just added.
v Go to “General checkout” on page 37 and run the firmware-based diagnostic
tests to determine if the server is running correctly.
v
Reinstall the new software or new device.
In the following tables, if the entry in the FRU/action column is a suggested action,
perform that action; if it is the name of a component, reseat the component and
replace it if necessary. The most likely cause of the symptom is listed first.
