Viewing event logs without restarting the compute node

If the compute node is not hung, methods are available for you to view one or more event logs without having to restart the compute node.

You can view the Chassis Management Module event log in the Flex System Manager Chassis Manager, or through the Event Log link in Flex System Manager management software. For more information about Flex System Manager management software, (if installed) see the "Flex System Manager Software: Installation and Service Guide".

You can also view the Chassis Management Module event log through the Event Log link by using the CMM displaylog command or the CMM web interface.

For more information about the CMM displaylog command, see the "Flex System Chassis Management Module: Command-Line Interface Reference Guide".
From the CMM web interface, select Event Log from the Chassis Management menu. For more information, see the "Flex System Chassis Management Module: User's Guide". All fields and options are described in the CMM web interface online help.

Note: If event IDs are not currently displayed in the Event Log page, you can enable them. To do so, click Filter Events and select the Event ID check box under Visible columns.

If you have installed DSA Portable Edition, you can use it to view the system-event log (as the IPMI event log), the operating-system event logs, or the merged DSA log. You can also use DSA Preboot to view these logs, although you must restart the compute node to use DSA Preboot. To install Portable DSA or DSA Preboot or to download a DSA Preboot CD image, go to the Lenovo Dynamic System Analysis (DSA) website.

If IPMItool is installed in the compute node, you can use it to view the system-event log. Most recent versions of the Linux operating system come with a current version of IPMItool. For information about IPMItool, complete the following steps.

Note: Changes are made periodically to the Lenovo website. The actual procedure might vary slightly from what is described in this document.

Go to the developerWorks website.
Click Linux.
Click the Linux blueprints tab.
Click Blueprints for Linux on IBM systems or Blueprints for Linux on Lenovo systems, and then click Using Intelligent Platform Management Interface (IPMI) on IBM Linux platforms or Using Intelligent Platform Management Interface (IPMI) on Lenovo Linux platforms.

The following table describes the methods that you can use to view the event logs, depending on the condition of the compute node. The first two conditions generally do not require that you restart the compute node.

Table 1. Methods for viewing event logs
Condition	Action
The compute node is not hung and is connected to a network.	Use any of the following methods: In a web browser, type the IP address of the Chassis Management Module and go to the Event Log page. Run Portable to view the event logs or create an output file that you can send to Support. Use IPMItool to view the system-event log.
The compute node is not hung and is not connected to a network.	Use IPMItool locally to view the system-event log.
The compute node is hung.	Use any of the following methods: If DSA Preboot is installed, restart the compute node and press F2 to start DSA Preboot and view the event logs. If DSA Preboot is not installed, insert the DSA Preboot CD and restart the compute node to start DSA Preboot and view the event logs. Alternatively, you can restart the compute node and press F1 to start the Setup utility and view the POST event log or system-event log. For more information, see Viewing event logs through the Setup utility.
