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. If you configure automatic problem notification, Lenovo Support is automatically alerted whenever a server encounters a potentially significant event.

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.

Note
  • For your server, the Lenovo XClarity Controller web page or command-line interface does not support the display of system utilization information for the following:

    • Processor

    • memory module

    • I/O

  • 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. If the server is managed by the Chassis Management Module 2 or by the Lenovo XClarity Administrator, alerts are automatically forwarded to those management applications.
  • The front operator panel and error LEDs
    The front operator panel 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 operator panel on the front of the server, then on the failed component. By viewing the LEDs in a particular order, you can often identify the source of the error.
  • 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.
