POST
When you turn on the server, it performs a series of tests to check the operation of
the server components and some optional devices in the server. This series of tests
is called the power-on self-test, or POST. This server does not use beep codes for
server status.
If a power-on password is set, you must type the password and press Enter, when
you are prompted, for POST to run.
Event 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 all BMC, POST, and system management
interrupt (SMI) events. You can view the system-event log from 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 from the Setup utility
To view the POST event log or system-event log, complete the following steps:
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.
