IMM event log
Use this information as an overview of the IMM event log.
The integrated management module II (IMM2) consolidates the system-management processor functionality,
video controller, and remote presence capabilities in a single chip on the system board. The IMM2 monitors
all components of the compute node and posts events in the IMM event log. In addition, most events are
also sent to the Chassis Management Module event log. You can view the IMM event log through the
Dynamic System Analysis (DSA) program (as the ASM event log).
To diagnose and resolve IMM error codes, see
Viewing event logs through the Setup utility
You can view the IMM and POST events through the Setup utility.
To view the POST event log or system-event log, complete the following steps:
Step 1.
Connect a keyboard, monitor, and mouse to the console breakout cable and connect the console
breakout cable to the compute node.
Step 2.
Turn on the compute node.
Step 3.
When the prompt <F1> Setup is displayed, press F1. If you have set both a power-on password and
an administrator password, you must type the administrator password to view the event logs.
Step 4.
Select System Event Logs and use one of the following procedures:
• To view the POST event log, select POST Event Viewer.
• To view the system-event log, select System Event Log.
Viewing event logs without restarting the compute node
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 using the Lenovo XClarity Administrator, in the Flex
System Manager Chassis Manager, or through the Event Log link in Flex System Manager management
software. For more information about the Lenovo XClarity Administrator, see

"Flex System Manager Software: Installation and Service Guide" at http://pic.dhe.ibm.com/infocenter/flexsys/
information/topic/com.ibm.acc.8731.doc/product_ page.html
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.
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.
