System Event Log Troubleshooting Guide for EPSD Platforms Based on Intel ® Xeon ® Processor E5
4600/2600/2400/1600/1400 Product Families Introduction
Revision 1.1 Intel order number G90620-002 3
board; it sends alerts and logs events when certain parameters exceed their preset thresholds,
indicating a potential failure of the system. The administrator can also remotely communicate
with the BMC to take some corrective action such as resetting or power cycling the system to
get a hung OS running again. These abilities save on the total cost of ownership of a system.
For Intel ® Server Boards and Intel ® Server Platforms, the BMC supports the industry standard
IPMI 2.0 Specification, enabling you to configure, monitor, and recover systems remotely.
1.2.2.1 System Event Log (SEL)
The BMC provides a centralized, non-volatile repository for critical, warning, and informational
system events called the System Event Log or SEL. By having the BMC manage the SEL and
logging func
tions, it helps to ensure that “post-mortem” logging information is available if a
failure occurs that disables the system processor(s).
The BMC allows access to SEL from in-band and out-of-band mechanisms. There are various
tools and utilities that can be used to access the SEL. There is the Intel
® SELView utility and
multiple open sourced IPMI tools.
1.2.3 Intel ® Intelligent Power Node Manager Version 2.0
Intel ® Intelligent Power Node Manager Version 2.0 (NM) is a platform-resident technology that
enforces power and thermal policies for the platform. These policies are applied by exploiting
subsystem knobs (such as processor P and T states) that can be used to control power
consumption. Intel
® Intelligent Power Node Manager enables data center power and thermal
management by exposing an external interface to management software through which platform
policies can be specified. It also enables specific data center power management usage models
such as power limiting.
The configuration and control commands are used by the external management software or
BMC to configure and control the Intel
® Intelligent Power Node Manager feature. Because
Platform Services firmware does not have any external interface, external commands are first
received by the BMC over LAN and then relayed to the Platform Services firmware over IPMB
channel. The BMC acts as a relay and the transport conversion device for these commands. For
simplicity, the commands from the management console might be encapsulated in a generic
CONFIG packet format (configuration data length, configuration data blob) to the BMC so that
the BMC doesn’t even have to parse the actual configuration data.
The BMC provides the access point for remote commands from external management SW and
generates alerts to them. Intel
® Intelligent Power Node Manager on Intel ® Manageability Engine
(Intel ® ME) is an IPMI satellite controller. A mechanism exists to forward commands to Intel ® ME
and then sends the response back to originator. Similarly events from Intel ® ME will be sent as
alerts outside of the BMC.
