CHAPTER 13 Troubleshooting
13.1 Overview
How to isolate system trouble when it occurs varies according to the conditions in which the units were operating
and the type of trouble.
The LCD panel shows any hardware error messages found during POST diagnostics or hardware errors
detected by the SCF while the system is running.
The results of the POST diagnostics can be confirmed from the ok prompt is.
If a system problem occurs while the operating system is running, an error message is displayed on the console
and that error message is saved in the /var/adm/messages file. The various I/O units can be diagnosed by using
the hardware diagnostics programs. These programs are contained in the "Enhanced Support Facility."
This chapter will give some tips to isolate hardware problems when trouble occurs.
IMPORTANT
Users should never attempt to repair the PRIMEPOWER themselves. Contact a service engineer for
repairs.
When the service engineer performs repairs, logging in at the system administrator level is sometimes
required. Please respond to the service engineer’s requests for logging in.
13.2 Checking Errors from the ok Prompt
After the POST (Power On Self Test) phase, entering the command shown in Table 13.1 from the ok prompt will
show the hardware configuration and the results of POST diagnostics. It takes a little time for the screen to appear
on the console after the power is turned on. If nothing appears on the console even after the power has been turned
on for a while, check the messages on the LCD panel, the state of the CHECK and POWER LEDs, and the console
connections.
Display of initial diagnostics results
Enter the command shown in Table 13.1 to display the results of the POST diagnostics.
Table 13.1 show-post-results Command
Command Function
show-post-results Displays the results of diagnostics on the
UPA clock, UPA module, PCI slots, memory
modules and on-board I/O on the console.
Also, the diagnostic results can be referred to by using the prtdiag (1M) command while the
operating system is running.
