CHAPTER 14 Troubleshooting
14.1 Overview
This chapter will give you some tips to isolate hardware problems of the GP7000F. The GP7000F has some
hardware features to diagnose and monitor the hardware, and it makes trouble shooting easy and less time
consuming.
LCD panel shows hardware error messages, if it is found during power-on diagnostics or while the system is
running. Also, the CHECK LED on the front panel light up, if the GP7000F has a problem.
When the ok prompt are shown on a console display, some commands are available to show results of the
power-on diagnostics.
If problems are occurred while the operating system is running, error messages are displayed on the console
and logged in the /var/adm/messages file. When the operating system is running, a variety of diagnostic
program can be used to verify the hardware system. For more information about the diagnostic program, refer
to the manuals of the "Basic Software Extension" or "Enhanced Support Facility".

the system console messages and the system log files.
