Error Messages - Sun Microsystems Enterprise 250 Owner's Manual

Figure 12–7
When a disk LED lights steadily and is green, it indicates that the slot is populated
and that the drive is receiving power. When an LED is green and blinking, it indicates
that there is activity on the disk. Some applications may use the LED to indicate a
fault on the disk drive. In this case, the LED changes color to yellow and remains lit.
The disk drive LEDs retain their state even when the system is powered off.

Error Messages

Error messages and other system messages are saved in the file
/var/adm/messages.
The two firmware-based diagnostic tools, POST and OBDiag, provide error messages
either locally on the system console or remotely on an RSC console. These error
messages can help to further refine your problem diagnosis. The amount of error
information displayed in diagnostic messages is determined by the value of the
OpenBoot PROM variable diag-verbosity. See "OBDiag Configuration Variables"
on page 242 for additional details.
Software Commands
System software provides Solaris and OBP commands that you can use to diagnose
problems. For more information on Solaris commands, see the appropriate man
pages. For additional information on OBP commands, see the OpenBoot 3.x
