Sun Microsystems X4140, X4240, X4440 manual Hardware Error Handling Summary

Hardware Error Handling Summary

TABLE D-1summarizes the most common hardware errors that you might encounter with these servers.

TABLE D-1	Hardware Error Handling Summary
			Logged (DMI
			Log or SP
Error	Description	Handling	SEL)	Fatal?

SP failure	The SP fails to boot
	upon application of
	system power.

SP failure	SP boots but fails
	POST.
BIOS POST	Server BIOS does
failure	not pass POST.

The SP controls the system reset, so the	Not logged	Fatal
system may power on, but will not come out
of reset.
• During power up, the SP's boot loader
turns on the power LED.
• During SP boot, Linux startup, and SP
sanity check, the power LED blinks.
• The LED is turned off when SP
management code (the IPMI stack) is
started.
• At exit of BIOS POST, the LED goes to
STEADY ON state.
The SP controls the system RESET, so the	Not logged	Fatal
system will not come out of reset.
There are fatal and non-fatal errors in POST.
The BIOS does detect some errors that are
announced during POST as POST codes on
the bottom right corner of the display on the
serial console and on the video display. Some
POST codes are forwarded to the SP for
logging.
The POST codes do not come out in
sequential order and some are repeated,
because some POST codes are issued by code
in add-in card BIOS expansion ROMs.
In the case of early POST failures (for
example, the BSP fails to operate correctly),
BIOS just halts without logging.
For some other POST failures subsequent to
memory and SP initialization, the BIOS logs a
message to the SP’s SEL.
