Sun Microsystems X4240, X4440, X4140 manual Correctable DIMM Errors

The lines in the display start with event numbers (in hex), followed by a description of the event. TABLE 3-1describes the contents of the display:

TABLE 3-1Lines in IPMI Output

Event (hex) Description

8UCE caused a Hypertransport sync flood which lead to system's warm reset. #0x02 refers to a reboot count maintained since the last AC power reset.

9BIOS detected and initiated 4 processors in system.

aBIOS detected a Sync Flood caused this reboot.

bBIOS detected a hardware error caused the Sync Flood.

cto 1e BIOS retrieved and reported some hardware evidence, including all processors' Machine Check Error registers (events 14 to 18).

1f	After BIOS detected that a UCE had occurred, it located the DIMM and
	reset. 0x03 refers to reboot count.
21 to 25	BIOS off-lined faulty DIMMs from system memory space and reported
	them. Each DIMM of a pair is being reported, since hardware UCE
	evidence cannot lead BIOS any further than detection of a faulty pair.

Correctable DIMM Errors

If a DIMM has 24 or more correctable errors in 24 hours, it is considered defective and should be replaced.

At this time, CEs are not logged in the server’s system event logs. They are reported or handled in the supported OS’s as follows:

■Windows Server:

a.A Machine Check error-message bubble appears on the task bar.

b.The user must manually open Event Viewer to view errors. Access Event Viewer through this menu path:

Start-->Administration Tools-->Event Viewer

c.The user can then view individual errors (by time) to see details of the error.

■Solaris:

Solaris FMA reports and (sometimes) retires memory with correctable Error Correction Code (ECC) errors. See your Solaris Operating System documentation for details. Use the command:

fmdump -eV
