Handling of Correctable Errors

This section lists facts and considerations about how the server handles correctable
errors.

■

During BIOS POST:

■

The BIOS polls the MCK registers.

■

The BIOS logs to DMI.

■

The BIOS logs to the SP SEL through the BMC.

■

The feature is turned off at OS boot time by default.

■

The following Linux versions report correctable ECC syndrome and memory fill
errors in /var/log, if kernel flag mce is indicated at boot time, or if mce is
enabled through kernel compile or installation:

■

RH3 Update5 single core

■

RH4 Update1+

■

SLES9 SP1+

■

The Linux kernel (x86_64/kernel/mce.c) repeats a report every 30 seconds
until another error is encountered and an 8131 flag is reset.

■

Solaris support provides full self-healing and automated diagnosis for the CPU
and Memory subsystems.
