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.
