       FreeIPMI - FreeIPMI overview


       FreeIPMI  provides  in-band  and out-of-band IPMI software based on the
       IPMI v1.5/2.0 specification.

What is IPMI?

       The IPMI  specification  defines  a  set  of  interfaces  for  platform
       management.  It  is  utilized  by  a wide variety of vendors for system
       management on motherboards. The features of IPMI that most  users  will
       be  interested  in are sensor monitoring, remote power control, serial-
       over-LAN (SOL), and system debugging. The FreeIPMI tools and  libraries
       listed  below  should  provide  users  with  the  ability to access and
       utilize these features.

Project Tools


       A tool to read information about a BMC such as device version  numbers,
       device support, and global IDs (guids).


       A  tool  to  configure  general  BMC  and  IPMI  information.  Supports
       configuration  of   usernames,   passwords,   networking   information,
       security, Serial-over-LAN (SOL), and other core fields.


       A tool/daemon to manage a BMC Watchdog. This tool is typically used for
       system timeout management and automatic system restarts in the event of
       a system crash.


       A   tool   to   manage/monitor   a  chassis,  such  as  chassis  power,
       identification (i.e. LED control), and status.


       A tool  to  read  field  replaceable  unit  (FRU)  information  from  a


       A  tool  to  read  and  manage IPMI System Event Log (SEL) records. SEL
       records store system event information and may be useful for  debugging


       A  tool  to  read IPMI sensor readings and sensor data repository (SDR)


       A tool for remote power control.


       A tool for Serial-over-Lan (SOL) console access.


       A tool for sensor monitoring and interpretation. The tool is similar to
       ipmi-sensors, but sensor readings are analyzed and mapped into Nominal,
       Warning, and Critical states.


       A tool that provides hex input/output of IPMI commands.


       A tool that can probe for information  about  the  location  of  a  BMC
       device, such as device addresses.

       A tool to configure IPMI chassis information. Supports configuration of
       boot device, power restore policy, and other chassis related fields.


       A tool to configure IPMI  sensors.  Supports  configuration  of  sensor
       thresholds, sensor events, and other sensor related fields.


       A tool to perform advanced BMC commands.


       An IPMI ping tool for debugging.


       A RMCP ping tool for debugging.


       An IPMI tool for OEM specific commands.


       A tool and daemon for IPMI node detection.

Project Libraries


       A C library that includes KCS, SSIF, and OpenIPMI drivers, IPMI 1.5 and
       IPMI 2.0 LAN communication interfaces, IPMI packet building  utilities,
       IPMI command utilities, and utilities for reading/interpreting/managing


       A library for Serial-over-Lan (SOL) console access. SOL console  access
       is  abstracted  into a file descriptor interface, so users may read and
       write console data through a file descriptor.


       A library for sensor monitoring and interpretation.  Sensor  monitoring
       and  interpretation  of those sensors is abstracted into an API with an
       iterator interface.


       A library for IPMI node detection.

Getting Started with IPMI

       IPMI can be used in-band (i.e. running on a machine locally) or out-of-
       band (i.e. connecting remotely).

       Most  FreeIPMI  tools  can  operate in-band by using one of the in-band
       drivers included. These in-band drivers include a direct KCS  interface
       driver,  a Linux SSIF driver through the SSIF device (i.e. /dev/i2c-0),
       the OpenIPMI Linux kernel driver (i.e. /dev/ipmi0), and the Sun/Solaris
       BMC  driver  (i.e.  /dev/bmc).  If  your  system  requires  the  use of
       installed drivers, those appropriate modules must be installed ahead of
       time.  However,  most  systems  should automatically load these drivers
       when appropriate.

       Under most scenarios, the FreeIPMI tools should automatically  discover
       which  in-band  interface  to use and the proper settings to use. Users
       may execute the tools on the command line to  begin  using  them.  Some
       motherboards  may  require  you  to  determine  driver type, addresses,
       paths, etc. on your own and pass them as command line  options  to  the
       tools.  You  may use ipmi-locate(8) to help determine this information.
       Other tools such as dmidecode(8) may also provide this information.

       To use IPMI out-of-band  with  tools  such  as  ipmipower(8)  or  ipmi-
       sensors(8),  the  remote machine’s BMC must first be configured for out
       of band communication. Typically, this  involves  setting  a  username,
       password, IP address, MAC address, and a few other parameters. This can
       be done using the tool bmc-config(8).  Additional information on how to
       configure  with  bmc-config(8)  can  be found in the bmc-config.conf(5)
       manpage. Some vendors may pre-configure their motherboards with default
       values  so  that  bmc-config(8)  can  be used remotely to configure the
       machine. However, most of the time, the BMC must be configured  in-band
       before  out-of-band  access can be allowed (for example, the correct IP
       address and MAC address must be configured).

       In order to remotely connect to a machine, you typically  must  specify
       the  host,  username,  and  password  for the tool in order to connect.
       Depending on  configuration  settings,  a  K_g  key,  privilege  level,
       authentication  type,  cipher suite id, or protocol version may need to
       be specified. Some vendors may have not implemented IPMI properly and a
       vendor specific workaround may also be necessary. See tool manpages for
       more information and general trouble-shooting information.


       In order to avoid typing in a long list  of  command  line  options  to
       specify IPMI communication requirements everytime a command is executed
       (i.e. driver paths, usernames, passwords, etc.), an  alternate  set  of
       default  values  can  be  set  for  most FreeIPMI tools in the FreeIPMI
       configuration file. See freeipmi.conf(5) for more information.

HPC Support

       Much  of  FreeIPMI  was  written  with  HPC  support   in   mind.   The
       configuration   tools  (  bmc-config(8),  pef-config(8),  ipmi-sensors-
       config(8), and ipmi-chassis-config(8) )  come  with  file  input/output
       support  so  that configuration can be copied and verified across nodes
       in a cluster. Most tools (like ipmipower(8) and ipmi-sensors(8) )  come
       with  hostrange  support  so  multiple  hosts  can  be specified on the
       command line at the same time and IPMI  can  be  executed  against  the
       hosts  in  parallel . See tool manpages for more information.  Also see
       the document freeipmi-hostrange.txt for detailed usage and explanation.
       The  ipmimonitoring(8)  tool interprets sensor readings as well as just
       reporting them. By mapping sensor readings into  NOMINAL,  WARNING,  or
       CRITICAL  states,  it  makes  monitoring  sensors  easier  across large
       numbers of nodes.
