Troubleshooting

Symptom
The purpose of this chapter is to provide a preferred methodology (strategies and procedures) and tools
for troubleshooting complex error and fault conditions.
This section is not intended to be a comprehensive guide to all of the tools that can be used for
troubleshooting the system. See the HPE Integrity Superdome X and Superdome 2 Onboard
Administrator User Guide and the HPE Integrity Superdome X and Superdome 2 Onboard Administrator
Command Line Interface User Guide for additional information on troubleshooting using the OA.

General troubleshooting methodology

The system provides the following sources of information for troubleshooting:
•

LED status information

• Insight Display
• OA CLI, Health Repository (HR) and Core Analysis Engine (CAE)
• OA GUI
NOTE:
Examples in this section might reflect other systems and not the currently supported configuration of
the Integrity Superdome X system.
LED status information
The LEDs provide initial status and health information. LED information should be verified by the other
sources of status information.
See LEDs and components on page 55 for more information.
TIP:
The OA CLI is the most efficient way to verify the information provided from LEDs.

OA access

You can access the OA by entering the 169.254.1.x address using either a Telnet session or a SSH
connection. This can be done by connecting a laptop to the service port on the OA tray using a standard
LAN cable using Telnet or by using a system which has access to the OA-management LAN (customer
LAN connected to the OA RJ45–port). See Connecting a PC to the OA service port for more
information about connecting to the OA service port.
IMPORTANT:
The OA service (Link Up) port is not to be confused with the serial port. The OA serial port is only
used for initial system setup. Once the network is configured, the OA should be always be accessed
using Telnet or SSH connection to the Service port.

OA CLI

The central point of communication for gaining system status is the active OA.
