●Precautions for Using Red Hat Enterprise Linux
(1) Settings in the system BIOS SETUP menu for installing the OS and for using
the server
In the system BIOS SETUP menu, changing the [BMC IRQ] setting to [Disabled] is required for
installing the OS and for using the server.
Change the setting by following the steps below.
The BIOS default setting value for [BMC IRQ] is set to [IRQ11].
Note that the setting is changed to [Disabled] as the factory default if Red Hat Enterprise Linux is
selected for BTO.
If other than Red Hat Enterprise Linux is selected for BTO or the BIOS settings are initialized
(Load Setup Default), changing the setting is required because it is set to [IRQ11].

For Red Hat Enterprise Linux 6, when the ECO function is enabled and the power consumption
exceeds the upper limit of the setting value, the following message may be logged in the syslog
(although there is no error in the server).
[Hardware Error]: Machine check events logged
The difference between the messages on actual errors in the server and on power control
operations can be identified by checking the Machine Check Event (MCE) logs (in
/var/log/mcelog).
The "Hardware Error" is logged when a request for the power control operations is received
and it does not indicate an error in the server if a message that is similar to the following and that
contains "THERMAL EVENT" is repeatedly logged in 8 lines in /var/log/mcelog at around the time
(within 5 minutes) when the message containing "Hardware Error" is logged in
/var/log/messages.
