Problem determination

Use the information in this section to isolate and resolve issues that you might encounter while using your server.

Lenovo servers can be configured to automatically notify Lenovo Support if certain events are generated. You can configure automatic notification, also known as Call Home, from management applications, such as the Lenovo XClarity Administrator. You may also configure Call Home from Lenovo XClarity Controller. Using the Call Home function, you can create a service forwarder that automatically sends service data for any managed device to Lenovo Support.

To isolate a problem, you should typically begin with the event log of the application that is managing the server:

  • If you are managing the server from the Lenovo XClarity Administrator, begin with the Lenovo XClarity Administrator event log.

  • If you are using some other management application, begin with the Lenovo XClarity Controller event log.

  • Event logs
    An alert is a message or other indication that signals an event or an impending event. Alerts are generated by the Lenovo XClarity Controller or by UEFI in the servers. These alerts are stored in the Lenovo XClarity Controller Event Log.
  • Light path diagnostics
    Light path diagnostics is a system of LEDs on various external and internal components of the server that leads you to the failed component. When an error occurs, LEDs are lit on the front I/O assembly, the rear panel, the system board, and the failed component. By viewing the following LEDs, you can often identify the system and device status and diagnose problems.
  • General problem determination procedures
    Use the information in this section to resolve problems if the event log does not contain specific errors or the server is inoperative.
  • Troubleshooting by symptom
    Use this information to find solutions to problems that have identifiable symptoms.
