Configuring IPMI support

Configuring IPMI support

Installing ipmitool command

To enable one of the drivers that use IPMI protocol for power and management actions (for example, ipmi), the ipmitool command must be present on the service node(s) where ironic-conductor is running. On most distros, it is provided as part of the ipmitool package. Source code is available at


Certain distros, notably Mac OS X and SLES, install openipmi instead of ipmitool by default. This driver is not compatible with openipmi as it relies on error handling options not provided by this tool.

Please refer to the IPMITool driver for information on how to use IPMItool-based drivers.

Validation and troubleshooting

Check that you can connect to, and authenticate with, the IPMI controller in your bare metal server by running ipmitool:

ipmitool -I lanplus -H <ip-address> -U <username> -P <password> chassis power status

where <ip-address> is the IP of the IPMI controller you want to access. This is not the bare metal node’s main IP. The IPMI controller should have its own unique IP.

If the above command doesn’t return the power status of the bare metal server, check that

  • ipmitool is installed and is available via the $PATH environment variable.
  • The IPMI controller on your bare metal server is turned on.
  • The IPMI controller credentials and IP address passed in the command are correct.
  • The conductor node has a route to the IPMI controller. This can be checked by just pinging the IPMI controller IP from the conductor node.

IPMI configuration

If there are slow or unresponsive BMCs in the environment, the min_command_interval configuration option in the [ipmi] section may need to be raised. The default is fairly conservative, as setting this timeout too low can cause older BMCs to crash and require a hard-reset.

Collecting sensor data

Bare Metal service supports sending IPMI sensor data to Telemetry with certain hardware types, such as ipmi, ilo and irmc. By default, support for sending IPMI sensor data to Telemetry is disabled. If you want to enable it, you should make the following two changes in ironic.conf:

send_sensor_data = true
driver = messagingv2

If you want to customize the sensor types which will be sent to Telemetry, change the send_sensor_data_types option. For example, the below settings will send information about temperature, fan, voltage from sensors to the Telemetry service:


Supported sensor types are defined by the Telemetry service, currently these are Temperature, Fan, Voltage, Current. Special value All (the default) designates all supported sensor types.
