The event log and chassis code viewers enables you to view chassis codes or event logs that are emitted throughout the entire server complex.

NOTE: On HP 9000 servers with HP PA-8700 processors, the equivalent of event logs is chassis codes.

To enter the event log viewer enter SL at the service processor Main menu. To exit the viewer type ^b (Control-b) to return to the Main menu.

Event logs are data that communicate information about system events from the source of the event to other parts of the server complex. Event log data indicates what event has occurred, when and where it happened, and its severity (the alert level).

All event logs pass from the event source through the service processor. The service processor takes any appropriate action and then reflects the event logs to all running nPartitions. If an nPartition is running event monitoring software, it may also take action based on the event logs (for example, sending notification e-mail).

System administrators, of course, may have interest in viewing various event logs—especially event logs that indicate failures or errors.

Hardware, software, and firmware events may emit event logs as a result of a failure or error, a major change in system state, or basic forward progress. For example: a fan failure, a machine check abort (MCA), the start of a boot process, hardware power on or off, and test completion all result in event logs being emitted.

NOTE: The front panel attention LED for a cell-based server cabinet is automatically turned on when one or more event logs of alert level 2 or higher have not yet been viewed by the administrator. When this attention LED is on, entering the chassis log viewer turns the LED off.

You can remotely check the on/off status of this attention LED by using the PS command, G option, from the service processor Command menu.

On cell-based servers, event logs are recorded in the server complex activity log (for events of alert level 0 or alert level 1) or the error log (for events alert level 2 or higher).

Log Viewing Options: Activity, Error, and Live Chassis Logs. When you enter the chassis log viewer by entering SL at the service processor (MP or GSP) Main menu, you can select from these viewers:

  • Activity Log Viewer. Allows you to browse recorded event logs of alert level 0 or 1.

  • Error Log Viewer. Allows you to browse recorded event logs of alert level 2 or higher.

  • Live Chassis Logs Viewer. Displays event logs in real time as they are emitted.

    By default, the live event log viewer has the Alert filter enabled, which causes it to display only the events of alert level 3 or higher.

    To view all event logs in real-time, type U for the Unfiltered option.

    You also can filter the live codes by cell (C) or nPartition (P). Cell filter: only display event logs emitted by a specific cell in the server complex. Partition filter: only display event logs emitted by hardware assigned to a specific nPartition.

When viewing event log logs, type V to change the display format. The viewers can show event logs in text format (T), keyword format (K), or raw hex format (R).
