30 Sun Fire V20z and Sun Fire V40z Servers, Server Management Guide • May, 2004
Lights Out Management (LOM)
On these servers, Lights Out Management is performed through IPMItool, a utility
for controlling IPMI-enabled devices.
Description
IPMItool is a simple command-line interface (CLI) to servers that support the
Intelligent Platform Management Interface (IPMI) v1.5 specification. It provides the
ability to:
■ Read the Sensor Data Record (SDR) and print sensor values
■ Display the contents of the System Event Log (SEL)
■ Print information about Field Replaceable Units (FRUs)
■ Read and set LAN configuration parameters
■ Perform chassis power control
Originally written to take advantage of IPMI-over-LAN interfaces, IPMItool is also
capable of using a system interface, as provided by a kernel device driver such as
OpenIPMI.
