CHAPTER 6

Using IPMI

This chapter describes the Intelligent Platform Management Interface (IPMI) functionality and lists the supported IPMI commands. It includes the following sections:

■“About IPMI” on page 61.

■“Supported IPMI 2.0 Commands” on page 63.

About IPMI

The Intelligent Platform Management Interface (IPMI) is an open-standard hardware management interface specification that defines a specific way for embedded management subsystems to communicate. IPMI information is exchanged through the service processor (SP), an IPMI-compliant hardware component. Using low-level hardware intelligence instead of the operating system has two main benefits: First, this configuration allows for out-of-band server management, and second, the operating system is not burdened with transporting system status data.

You can manage your server with the IPMI v.1.5/2.0 on your server or stand-alone server, which runs a daemon to do the following:

■Support low pin count (LPC) host interface in two modes:

■KCS Mode (3 channels)

■BT Mode (1 channel with 32 bytes of FIFO)

■Support dedicated NIC or shared lights out management (LOM)

■Support Serial-On-LAN (SOL)

■Customize FRU/Sensor Data Record data (firmware independent)

■Provide KVM over IP (remote access to the server)

■Enable the user interface (UI) for hot key definitions (for example Ctrl-Alt-Del)
