v System-event log: This log contains all IMM, POST, and system management
interrupt (SMI) events. You can view the system-event log through the Setup
Utility and through the Dynamic System Analysis (DSA) program (as the IPMI
event log).
The system-event log is limited in size. When it is full, new entries will not
overwrite existing entries; therefore, you must periodically save and then clear
the system-event log through the Setup Utility when the IMM logs an event that
indicates that the log is more than 75% full. When you are troubleshooting, you
might have to save and then clear the system-event log to make the most recent
events available for analysis.
Messages are listed on the left side of the screen, and details about the selected
message are displayed on the right side of the screen. To move from one entry
to the next, use the Up Arrow (↑) and Down Arrow (↓) keys.
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.
v Integrated management module (IMM) event log: This log contains a filtered
subset of all IMM, POST, and system management interrupt (SMI) events. You
can view the IMM event log through the IMM Web interface and through the
Dynamic System Analysis (DSA) program (as the ASM event log).
v DSA 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 event log (as the ASM event log), and the operating-system
event logs. You can view the DSA log through the DSA program.
Viewing event logs through the Setup Utility
To view the POST event log or system-event log, do the following:
1. Turn on the server.
2. 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.
3. Select System Event Logs and use one of the following procedures:
v To view the POST event log, select POST Event Viewer.
v To view the system-event log, select System Event Log.
Viewing event logs without restarting the server
If the server is not hung, methods are available for you to view one or more event
logs without having to restart the server.
If you have installed Portable or Installable Dynamic System Analysis (DSA), you
can use it to view the system-event log (as the IPMI event log), the IMM event log
(as the ASM event log), 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. To install
Portable DSA, Installable DSA, or DSA Preboot or to download a DSA Preboot CD
image, go to http://www.lenovo.com/support and complete the following steps.
Note: Changes are made periodically to the Lenovo Web site. The actual
procedure might vary slightly from what is described in this document.
1. Go to: http://www.lenovo.com/support.
2. Enter your product number (machine type and model number) or select Servers
and Storage from the Select your product list.
