System Event Log Troubleshooting Guide for Intel

Introduction

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

®

SELViewer and multiple open sourced IPMI tools.

Intel

Intelligent Power Node Manager version 1.5 (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 (config data length, config 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

®

Intel

®

ME) is an IPMI satellite controller. A mechanism needs to exist to forward commands to

ME and send response back to originator. Similarly events from Intel

®

ME have to be sent as alerts outside of the BMC. It is the responsibility of BMC to implement these mechanisms for communication with Intel

Intelligent Power Node Manager.
