Determining the Cause of a Problem Condition

To isolate the cause of a problem condition:
1. Verify the error.
Make sure it is not an erroneous error message. Is the error repeatable? Is the error
message affecting the HP server's operation or performance?
2. Check the most recently added items added, both hardware and software.
3. Remove any third-party components.
4. Make sure the server's BIOS is updated to the latest version posted in HP's website.
Flashing/updating the system BIOS and clearing CMOS will resolve many different
issues. Refer to Chapter 5 for related procedures.
5. Make sure all firmware/BIOS revisions on any controllers are kept current.
6. Make sure that only HP-provided drivers are used for all HP devices used in the server.
This includes HP drivers for the initial installation of any NOS that is supported by the
server.
7. Check all cables and power connections, including those in the rack.
8. If the server is not powering on, unplug the AC power cord(s) and wait for 20 seconds
then plug the AC power cords in again and restart the server. Check for normal operation.
9. Verify that all cables and boards are securely plugged into their appropriate connectors
and slots.
10. If the problem still persists, simplify the server's configuration. The minimum
requirements include:
•
•
•
•
•
11. Reconnect the power cords and power on the server.
12. If the server is operational, power back down and reinstall one component at a time and
power on the server after the installation of each component to try and determine which
component is causing the problem.
