The Clever Platform Administration Interface (IPMI) is an ordinary that requires its personal processor, apart from the primary one the system makes use of, as a result of it really works independently in monitoring and sustaining the platform. Usually, IPMI can proceed working even when the primary processor is turned off. Do word although that software program administration is outdoors IPMI’s scope.

Basically, IPMI serves as a bridge that relays system data principally for monitoring functions. Its upkeep or administration performance is secondary and fairly minor. In an effort to increase IPMI capabilities, many firms and organizations have constructed extra in depth administration management into IPMI utilizing OEM extensions.

Supermicro servers’ IPMI may be configured utilizing BIOS by a VGA console, IPMICFG (Supermicro proprietary instrument), or an open-source utility referred to as IPMItool. This text will give attention to utilizing IPMItool. 


To configure an IPMI with an area IPMItool, do the next steps:

1. Set the supply of the configuration, often left as “none”

ipmitool lan set ipsrc none | static | dhcp | bios

2. Set the IP tackle

ipmitool lan set ipaddr <x.x.x.x>

3. Set the IP netmask

ipmitool lan set netmask <x.x.x.x>

4. Set the default gateway’s IP tackle

ipmitool lan set defgw ipaddr <x.x.x.x>

5. Allow entry

ipmitool lan set entry on

Usually, IPMI community settings ought to already be pre-configured by your internet hosting supplier. Do word that altering these settings might render your IPMI controller inaccessible.

To examine the present LAN configuration run:

ipmitool lan print

To configure person entry, do the next steps:

1. Verify for pre-configured customers. Observe that person ID 2 is ADMIN.

ipmitool person listing

Observe: Any person can have administrator privileges, however that is assigned to person 2 by default. 

2. Rename the ADMIN person 

ipmitool person set identify 2 <identify> 

3. Set a brand new password for the ADMIN person

ipmitool person set password 2 <password>

4. Person is enabled by default. You’ll be able to set to “disable,” as wanted. 

ipmitool person disable 2


    • SuperMicro default login is ADMIN and default password is ADMIN.
    • Use one other ID as an alternative of two for a unique person.

To examine for primary community connectivity to the interface, you’ll be able to ping the IP tackle: ping <ipaddr> 

To examine if the interface is accessible by way of community and a session might be established, you’ll be able to run the next command: 

ipmitool -I lanplus -H <ipaddr> -U <username> session data all 

Observe: The password can be prompted when checking all at present established classes.

So that you’ll be requested for the password solely as soon as and in case it’s worthwhile to enter multiple command, you’ll be able to choose to enter an interactive shell:

 ipmitool -I lanplus -H <ipaddr> -U <username> shell 

The IPMItool Execute command runs the file specified, with every line in it learn as a whole command:

        ipmitool -I lanplus -H <ipaddr> -U <username> exec <filename>

Notes: Every line might have an non-obligatory remark on the finish of the road, delimited with the pound image (“#”). Under is an instance of a command file with two strains.

        sdr listing # get an inventory of sdr data

        sel listing # get an inventory of sel data


Under are just a few examples of utilizing the IPMItool utility in day-to-day server upkeep:

  • Checking present server energy standing, whether or not on or off

    ipmitool -I lanplus -H <ipaddr> -U <username> energy standing

  • Do any of the next energy controls: Server Energy On, Server Reset, Exhausting Energy Off (lengthy press on analog energy button), Delicate Energy Off (ACPI shutdown, brief press on analog energy button)

    ipmitool -I lanplus -H <ipaddr> -U <username> energy <on | reset | off | delicate> 

Observe: For Delicate Energy Off to work, your OS ought to help ACPI occasions. Linux requires working “acpid,” whereas Home windows methods require some registry/group coverage edits relying on the OS model.

  • Coming into BIOS configuration with out urgent the F2 key throughout loading

    ipmitool -I lanplus -H <ipaddr> -U <username> chassis bootdev bios


    • By doing this, the system will boot on to the BIOS setup on the subsequent reboot.
    • You’ll be able to change “bios” with “disk” as well from an HDD.
    • You’ll be able to change “bios” with “pxe” as well from a networked boot-capable card (PXE boot).


  • Enabling serial over LAN (SOL) to emulate a serial (COM) port on the IPMI controller

1. Allow this motion within the server BIOS and set mandatory parameters. We advocate setting 115200 as velocity for SOL. Save your settings.

2. Run the next command:

 ipmitool -I lanplus -H <ipaddr> -U <username> sol activate.


    • You will note BIOS load after a reboot. For those who press DEL, you’ll be able to navigate by the BIOS setup.
    • GRUB, a boot load supervisor, can even work together with SOL.

You should utilize SOL for to handle the OS of Unix-based methods. For Linux,add “console=ttyS1,115200” to kernel command line in your boot loader config. Keep in mind to make use of the suitable serial port quantity. In case your system has two actual COM ports and SOL is enabled, the SOL port turns into zero-based #2, “ttyS2.” This may allow kernel output redirection to SOL port. Some methods like CentOS Linux come pre-installed with SOL enter detection. It is a nice characteristic. You’ll be able to even copy-paste textual content over the SOL, a a lot better choice than the VGA console redirection of the Java applet.

  • Monitoring system occasion logs (SEL) to identify anomalies like a RAM ECC error

ipmitool -I lanplus -H <ipaddr> -U <username> sel listing

Utilizing the above command can provide the output just like the one beneath:

     1 | 06/06/2014 | 18:26:16 | Reminiscence | Correctable ECC | Asserted | CPU 0 DIMM 8

Observe: This output exhibits one of many reminiscence modules (#8) simply triggered a correctable ECC error. Because the output is only a stdout textual content, a system administrator can use it in a script to observe general machine well being with phrases like “error” or “critical” to set off an alert.

  • Monitoring {hardware} elements within the sensor listing like CPU, fan, and battery 

ipmitool -I lanplus -H <ipaddr> -U <username> sensor listing 


If the IPMI Controller hangs, run the next command:

ipmitool -I lanplus -H <ipaddr> -U <username> reset chilly 

Doing it will reboot the IPMI controller with out rebooting the OS.

If the IPMI Controller turns into unreachable, do a full AC cycle by eradicating the server energy cords and reconnecting them again in after one minute. Doing it will have an effect on your OS. Observe that rebooting the OS won’t reboot IPMI Controller .
