Error logs
Error codes and messages are displayed in the following types of event logs:
v
POST event log: This log contains the three most recent error codes and
messages that were generated during POST. You can view the POST event log
through the Setup utility.
v System-event log: This log contains POST and system management interrupt
(SMI) events and all events that are generated by the BMC that is embedded in
the IMM. 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 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 Dynamic System Analysis (DSA)
program (as the ASM event log).
v
Advanced management module event log: This log contains a filtered subset of
IMM, POST, and system management interrupt (SMI) events. You can view the
advanced management module event log through the advanced management
module Web interface.
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 chassis-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
Use this information to view the IMM log through the Setup utility.
For complete information about using the Setup utility, see “Using the Setup
utility” on page 21.
To view the POST event log or system-event log, complete the following steps:
1. Turn on the blade 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 blade server
If the blade server is not hung, methods are available for you to view one or more
event logs without having to restart the blade server.
