Viewing Event Logs Without Restarting The Server - Lenovo System x3750 M4 Installation And Service Manual

Some IMM sensors cause assertion events to be logged when their setpoints are reached. When a
setpoint condition no longer exists, a corresponding deassertion event is logged. However, not all events
are assertion-type events.
• Integrated management module event log: This log contains a filtered subset of all IMM2, POST, and
system management interrupt (SMI) events. You can view the IMM2 event log through the IMM2 web
interface. For more information, see "Logging on to the IMM2 web interface" on page 147. You can also
view the IMM2 event log through the Dynamic System Analysis (DSA) program (as the ASM event log).
For more information about IMM2 error messages, see Appendix D "Integrated management module II
(IMM2) error messages" on page 509.
• DSA event log: This log is generated by the Dynamic System Analysis (DSA) program, and it is a
chronologically ordered merge of the system-event log (as the IPMI event log), the IMM chassis-event log
(as the ASM event log), and the operating-system event logs. You can view the DSA event log through the
DSA program (see "Viewing event logs without restarting the server" on page 174). For more information
about DSA and DSA messages, see "Dynamic System Analysis" on page 176 and Appendix B "DSA
diagnostic test results" on page 319.
For more information about viewing the logs or clearing the logs, see "Viewing event logs through the
Setup utility" on page 174, "Viewing event logs without restarting the server" on page 174, and "Clearing
the error logs" on page 175.
Viewing event logs through the Setup utility
Use this information to view the POST event and system-event logs through the Setup utility.
To view the POST event log or system-event log, complete the following steps:
Step 1. Turn on the server.
When the prompt <F1> Setup is displayed, press F1. If you have set both a power-on password
Step 2.
and an administrator password, you must type the administrator password to view the event logs.
Step 3. 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 server

If the server is not hung and the IMM2 is connected to a network, methods are available for you to view one
or more event logs without having to restart the server.
If you have installed Dynamic System Analysis (DSA) Portable, you can use it to view the system-event
log (as the IPMI event log), or the IMM2 event log (as the ASM 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 server to use DSA Preboot. The server comes with DSA Preboot stored in integrated USB
memory. To install DSA Portable or check for and download a later version of DSA Preboot CD image, go to
https://support.lenovo.com/us/ en/documents/LNVO-DSA.
If IPMItool is installed in the server, 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 an overview of IPMI, go to
http://www.ibm.com/developerworks/linux/blueprints/ and click Using Intelligent Platform Management
Interface (IPMI) on IBM Linux platforms.
You can view the IMM2 event log through the Event Log link in the IMM2 web interface. For more
information, see "Logging on to the IMM2 web interface" on page 147.
