ILOM notes

IPMI Intelligent Platform Management Interface

  • The IPMI card is found in Supermicro motherboards. It is Supermicro's LOM card. It is either built into the motherboard or comes as an add-on BMC Base Management Card.
  • A built-in IPMI shares its RJ45 connection with the first ethernet port, called eth0 in Linux, but referred to as ETH1 in the IPMI documentation.
  • The add-on card has a special connector on the motherboard, it does not occupy a PCI slot. The add-on card uses a 15" long USB cable to connect an RJ45 jack on a card slot bracket. So it will occupy a PCI slot bracket on the back of the PC. The add-on card has its own RJ45 connection, it doesn't share with eth0. On the bottom of the card is the serial number.


  • The card will come with an install CD. Put the IPMI CLI application on the system, preferably in an admin account, such as /home/cscf-adm/cli. For a 64 bit Linux system it is ipmicfg-linux.x86_64. Before continuing with the next step get a name and IP address for the IPMI.
  • See ClusterToolsIPMITOOL

Installing Firmware

Get flash software from CD
  • /media/cdrom0/IPMI_Solution/Utility/linux_flash_utility_64bit/*.*
  • /media/cdrom0/Firmware/SIMxx/ugsim157.bin
  • $ sudo sh
There may be two versions of the firmware on the CD. Determine which is for your card. Note the version number is in the software name e.g. ugsim157 is version 1.57.
  • $ sudo ./updatefw.x86_64 -f ugsim157.bin
This requires several minutes. It will show a percentage of the progress.

INSTALL Linux IPMIView Remote Application

If the system has Java 32 bit version you may need to install 32 bit libraries before installing IPMIView.
  • $ apt-cache search -n ia32
  • $ apt-get install ia32-libs

Connect to the IPMI Card

  • Web:
    • Connect via a web interface:
    • IpmiWeb access from Firefox on Ubuntu
  • IPMIview

Adding a Machine to IPMIView

<nsb;>Search for available IPMI cards in an IP range
  • In the IPMIView applciation top menu File > Discover IPMI Device
    • This opens the "IPMI Device Discovering" dialog.
  • Enter the "Network IP From" IP address of the IPMI card and press Start button.
  • Select the name of the card from the list and press Save button.
  • The main screen should show the card under the "IPMI Domain" column. Press Exit to leave the discovery dialog.
  • Top menu File > Save Configuration

<nsb;>Alternatively add a system to the "IPMI Domain" column.

  • Top menu File > New > System
  • Enter IP and name of the IPMI card
    • The name should appear in the system list

<nsb;>Save the configuration

  • Top menu File > Save Configuration

Using the IPMI Card

Double-click the machine name in the "IPMI Domain" column in the IPMIView interface to connect to a machine IPMI card or use a browser.
First Login
  • Use the default factory name and password ADMIN, ADMIN
    • In the web interface change the password under the heading "Management and Change Password" links
      • The ADMIN user is the super user. In the web interface it can create new users, including those with admin rights. Other users, including admins, cannot create or manage users.
    • In the IPMIView double-click the card under the "IPMI Domain" column.
      • In the main dialog it will ask for Login. Use the factory default ADMIN, ADMIN for ID and Password.
      • It will confirm if the card is connected and several tabs will show at the bottom of the main dialog.
      • Select the "Users" tab to change the default password for ADMIN. Also add in the CSCF LOM ID and Password and set privileges.
      • Also enter the serial number for the device found on the card in the FRU information section.
  • ADMIN is the superuser
    • In the web interface it is the only user that can create new users
    • In the IPMIView any user with admin privileges may create or administer users

        • Download the csr.txt file (cert. signing request)
        • Use the csr.txt file to apply for an SSL certificate file and use the SSL cert file to Upload to the IPMI card
        • Obtaining a certificate via IST or GlobalSign may be require day. It is OK to exit the IPMI login. When returning to the IPMI web page the certification page will still be waiting for the cert.
        • When a cert has been obtained use the Upload button to apply the cert.
        • Browsers with have to accept the cert if it is UW/IST-CA assigned (grad image may include UW/IST-CA as recognized)
      • General certificate information IST
      • Create a GlobalSign certificate instructions
    • Date/Time
      • Choose synchronize with NTP server.

For the email address username@domainname, you should use

Since ipmitool runs on the machine with the IPMI card, what if the machine is inaccessible?
Use ipmitool from a remote machine.
In ssh riemann17 terminal, could not get ipmitool to report any information on riemann17. It wouldn't actually connect...

Using SSH to the IPMI card

The BMC card can be accessed by SSH. The card may run a BusyBox linux. This can be handy if the web interface port has changed to an unknown number.
Once connected run netstat to list the ports (there may be more than one) used by the web service called "webgo".

# netstat -tulpn
Active Internet connections (only servers)

udp        0      0   *                          325/
Then try each port on a browser e.g. http://ipaddress:16416 until the login web page is displayed. Once logged into the IPMI go to the configure tab and change the http port to 80.
