Detecting Faults (Oracle Solaris OS Files and
Commands)
With the Oracle Solaris OS running on the server, you have the full complement of
Oracle Solaris OS files and commands available for collecting information and for
troubleshooting.
If POST, ILOM, or the Oracle Solaris PSH features do not indicate the source of a
fault, check the message buffer and log files for notifications for faults. Hard drive
faults are usually captured by the Oracle Solaris message files.
Use the dmesg command to view the most recent system message. To view the
system messages log file, view the contents of the /var/adm/messages file.
