Chapter 8. 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.

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 Lenovo XClarity Administrator, alerts are automatically
forwarded to this management application.
Note: For a listing of events, including user actions that might need to be performed to recover from an
event, see the Messages and Codes Reference, which is available at

Lenovo XClarity Controller event log
The Lenovo XClarity Controller monitors the physical state of the server and its components using sensors
that measure internal physical variables such as temperature, power-supply voltages, fan speeds, and
component status. The Lenovo XClarity Controller provides various interfaces to systems management
software and to system administrators and users to enable remote management and control of a server.
