Collecting Information From Solaris OS
Files and Commands
With the Solaris OS running on the Sun Fire T2000 server, you have the full
compliment of Solaris OS files and commands available for collecting information
and for troubleshooting.
In the event that POST, ALOM, or the Solaris PSH features did 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 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.

To Check the Message Buffer

▼
1. Log in as superuser.
2. Issue the dmesg command:

To View System Message Log Files

The error logging daemon, syslogd automatically records various system
warnings, errors, and faults in message files. These messages can alert you to system
problems such as a device that is about to fail.
The /var/adm directory contains several message files. The most recent messages
are in the /var/adm/messages file. After a period of time (usually every ten days),
a new messages file is automatically created. The original contents of the
messages file are rotated to a file named messages.1. Over a period of time, the
messages are further rotated to messages.2 and messages.3, and then deleted.
1. Log in as superuser.
