Hypothetical Troubleshooting Scenario
The following describes a hypothetical troubleshooting scenario that might occur with your hp Integrity rx4640 Server.
1. This is the entry point to the troubleshooting process. Here, you pick from a set of symptoms, ranging from very simple
(System LED is blinking) to the most difficult (MCA has occurred). The following is a list of symptom examples:
•
System LED blinking
•
System will not power up
•
System will not boot
•
EMS event message received
•
Machine check abort (MCA) occurred
2. This step narrows down the observed problem to the specific troubleshooting procedure required. Here, you isolate the
failure to a specific part of the machine so that you can perform more detailed troubleshooting. For example:
•
Problem-System LED blinking
If the LED is the system alert on the control console, analyze the last error logged by the management processor.
3. At this point you will probably know which component of your HP Server needs attention. For example, if the symptom
was “System will not power up,” then the initial troubleshooting procedure may have led to a problem with the DC power
supplies (48V) not coming up after the power switch was turned on.
4. You have now reached the point where the failed Field Replaceable Unit (FRU or FRUs) have been identified and need to
be replaced. You must now perform the specific remove-and-replace and verification steps. See Chapter 7, “Removing
and Replacing Components,” for remove-and-replace procedures on all FRUs in your HP Server.
NOTE
If multiple FRUs are identified as part of the solution, a fix cannot be guaranteed unless all identified
failed FRUs are replaced.
5. There may be specific recovery procedures you need to perform to finish the repair. For example, if the management
processor is replaced, you will need to restore customer-specific information such as user profiles, network IDs, and
passwords. See Chapter 4, “Installing Additional Components and Configuring,” for procedures on setting up your
management processor.
