Remote Troubleshooting Capabilities; System Console Logging - Sun Microsystems Sun Fire V445 Server Administration Manual

Remote Troubleshooting Capabilities

You can use the Sun Advanced Lights Out Manager (ALOM) system controller to
troubleshoot and diagnose the system remotely. The ALOM system controller
enables you to do the following:
Turn system power on and off
Control the Locator indicator
Change OpenBoot configuration variables
View system environmental status information
View system event logs
In addition, you can use the ALOM system controller to access the system console,
provided it has not been redirected. System console access enables you to do the
following:
Run OpenBoot Diagnostics tests
View Solaris OS output
View POST output
Issue firmware commands at the ok prompt
View error events when the Solaris OS terminates abruptly

Advanced Lights Out Manager (ALOM) Online Help.

System Console Logging

Console logging is the ability to collect and log system console output. Console
logging captures console messages so that system failure data, like Fatal Reset error
details and POST output, can be recorded and analyzed.
Console logging is especially valuable when troubleshooting Fatal Reset errors and
RED State Exceptions. In these conditions, the Solaris OS terminates abruptly, and
although it sends messages to the system console, the OS software does not log any
messages in traditional file system locations like the /var/adm/messages file.
The error logging daemon, syslogd, automatically records various system
warnings and errors in message files. By default, many of these system messages are
displayed on the system console and are stored in the /var/adm/messages file.
Note – Solaris 10 moves CPU and memory hardware detected data from the
/var/adm/messages file to the fault management components. This make it easier
to locate hardware events and to facilitate predictive self healing.
