Sun Microsystems X4440, X4240, X4140 manual Note the following considerations for this revision

Note – If the error is on low 1MB, the BIOS freezes after rebooting. Therefore, no DMI log is recorded.

■An example of the error reported by the SEL through IPMI 2.0 is as follows:

■When low memory is erroneous, the BIOS is frozen on pre-boot low memory test because the BIOS cannot decompress itself into faulty DRAM and execute the following items:

ipmitool> sel list
100	08/26/2005		11:36:09 OEM #0xfb
200		08/26/2005	11:36:12 System	Firmware Error No usable system memory
300		08/26/2005	11:36:12 Memory	Memory Device Disabled CPU 0 DIMM 0

■When the faulty DIMM is beyond the BIOS's low 1MB extraction space, proper boot happens:

ipmitool> sel list

100 08/26/2005 05:04:04 OEM #0xfb

200 08/26/2005 05:04:09 Memory Memory Device Disabled CPU 0 DIMM 0

■Note the following considerations for this revision:

■Uncorrectable ECC Memory Error is not reported.

■Multi-bit ECC errors are reported as Memory Device Disabled.

■On first reboot, BIOS logs a HyperTransport Error in the DMI log.

■The BIOS disables the DIMM.

■The BIOS sends the SEL records to the BMC.

■The BIOS reboots again.

■The BIOS skips the faulty DIMM on the next POST memory test.

■The BIOS reports available memory, excluding the faulty DIMM pair.
