v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)
disables a failing DIMM that is detected during POST, and the IMM2 lights the
associated system error LED and the failing DIMM error LED.
v System event-log (SEL).
v ROM-based IMM2 firmware flash updates.
v Auto Boot Failure Recovery (ABR).
v Nonmaskable interrupt (NMI) detection and reporting.
v Automatic Server Restart (ASR) when POST is not complete or the operating
system hangs and the operating system watchdog timer times-out. The IMM2
allows the administrator to generate a nonmaskable interrupt (NMI) by pressing
an NMI button on the system board for an operating-system memory dump. ASR
is supported by IPMI.
v Intelligent Platform Management Interface (IPMI) Specification V2.0 and
Intelligent Platform Management Bus (IPMB) support.
v Serial over LAN (SOL).
v Power/reset control (power-on, hard and soft shutdown, hard and soft reset).
v Alerts (IPMI style PET traps).
Using IPMItool
IPMItool provides various tools that you can use to manage and configure an IPMI
system. You can use IPMItool in-band to manage and configure the IMM2. For
more information about IPMItool, or to download IPMItool, go to
http://sourceforge.net/
Managing tools and utilities with IMM2 and IBM System x Server
Firmware
This section describes the tools and utilities that are supported by IMM2 and IBM
System x Server Firmware. The IBM tools that you use to manage the IMM2
in-band do not require you to install device drivers. However, if you choose to use
certain tools such as IPMItool in-band, you must install the OpenIPMI drivers.
Updates and downloads for IBM systems-management tools and utilities are
available on the IBM website. To check for updates to tools and utilities, complete
the following steps.
Note: Changes are made periodically to the IBM website. Procedures for locating
firmware and documentation might vary slightly from what is described in this
document. See http://www-947.ibm.com/support/entry/portal/
docdisplay?brand=5000008&lndocid=TOOL-CENTER.
Using IBM Advanced Settings Utility (ASU)
IBM Advanced Settings Utility (ASU) version 3.0.0 or later is required to manage
IMM2. ASU is a tool that you can use to modify firmware settings from the
command-line interface on multiple operating-system platforms. It also enables you
to issue selected IMM2 setup commands. You can use ASU in-band to manage and
configure the IMM2.
For more information about the ASU, go to http://www.ibm.com/support/entry/portal/
docdisplay?lndocid=TOOL-ASU.
