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.
■ FIGURE D-2 shows an example of a DMI log screen from BIOS Setup Page:
