Edit mcelog File if Faults Are Not Present in the Fault Management Database

Language:

If the entry raw = yes in the mcelog.conf file is commented out, the Oracle Linux Fault Management software cannot obtain the information it needs to create a fault case. If that happens, fault cases for machine check events processed by mcelog are not added to the fault management database.

Confirm that the format of mcelog file messages are in the raw format by opening /var/log/mcelog in a text editor.

The following table shows an example of a default message and a "raw" message (required by Oracle Linux FMA).

If the messages in the mcelog file are in the default format, edit the /etc/mcelog/mcelog.conf file to uncomment the “raw = yes” entry.
Then restart the mcelog daemon, as follows:
service mcelogd restart
