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.
