The ironic.drivers.modules.ipmitool Module

IPMI power manager driver.

Uses the ‘ipmitool’ command (http://ipmitool.sourceforge.net/) to remotely manage hardware. This includes setting the boot device, getting a serial-over-LAN console, and controlling the power state of the machine.

NOTE THAT CERTAIN DISTROS MAY INSTALL openipmi BY DEFAULT, INSTEAD OF ipmitool, WHICH PROVIDES DIFFERENT COMMAND-LINE OPTIONS AND IS NOT SUPPORTED BY THIS DRIVER.

class ironic.drivers.modules.ipmitool.IPMIManagement

get_boot_device(task)

Get the current boot device for the task’s node.

Returns the current boot device of the node.

Parameters:task – a task from TaskManager. Raises:InvalidParameterValue if required IPMI parameters are missing. Raises:IPMIFailure on an error from ipmitool. Raises:MissingParameterValue if a required parameter is missing. Returns:a dictionary containing:

boot_device:the boot device, one of ironic.common.boot_devices or None if it is unknown. persistent:Whether the boot device will persist to all future boots or not, None if it is unknown.

get_properties()

get_sensors_data(task)

Parameters:task – a TaskManager instance. Raises:FailedToGetSensorData when getting the sensor data fails. Raises:FailedToParseSensorData when parsing sensor data fails. Raises:InvalidParameterValue if required ipmi parameters are missing Raises:MissingParameterValue if a required parameter is missing. Returns:returns a dict of sensor data group by sensor type.

get_supported_boot_devices(task)

Get a list of the supported boot devices.

Parameters:task – a task from TaskManager. Returns:A list with the supported boot devices defined in ironic.common.boot_devices.

set_boot_device(*args, **kwargs)

Set the boot device for the task’s node.

Set the boot device to use on next reboot of the node.

Parameters:

• task – a task from TaskManager.
• device – the boot device, one of ironic.common.boot_devices.
• persistent – Boolean value. True if the boot device will persist to all future boots, False if not. Default: False.

Raises:

InvalidParameterValue if an invalid boot device is specified

Raises:

MissingParameterValue if required ipmi parameters are missing.

Raises:

IPMIFailure on an error from ipmitool.

validate(task)

Check that ‘driver_info’ contains IPMI credentials.

Validates whether the ‘driver_info’ property of the supplied task’s node contains the required credentials information.

Parameters:task – a task from TaskManager. Raises:InvalidParameterValue if required IPMI parameters are missing. Raises:MissingParameterValue if a required parameter is missing.

class ironic.drivers.modules.ipmitool.IPMIPower

Bases: ironic.drivers.base.PowerInterface

get_power_state(task)

Get the current power state of the task’s node.

Parameters:task – a TaskManager instance containing the node to act on. Returns:one of ironic.common.states POWER_OFF, POWER_ON or ERROR. Raises:InvalidParameterValue if required ipmi parameters are missing. Raises:MissingParameterValue if a required parameter is missing. Raises:IPMIFailure on an error from ipmitool (from _power_status call).

get_properties()

reboot(*args, **kwargs)

Cycles the power to the task’s node.

Parameters:task – a TaskManager instance containing the node to act on. Raises:MissingParameterValue if required ipmi parameters are missing. Raises:InvalidParameterValue if an invalid power state was specified. Raises:PowerStateFailure if the final state of the node is not POWER_ON.

set_power_state(*args, **kwargs)

Turn the power on or off.

Parameters:

• task – a TaskManager instance containing the node to act on.
• pstate – The desired power state, one of ironic.common.states POWER_ON, POWER_OFF.

Raises:

InvalidParameterValue if an invalid power state was specified.

Raises:

MissingParameterValue if required ipmi parameters are missing

Raises:

PowerStateFailure if the power couldn’t be set to pstate.

validate(task)

Validate driver_info for ipmitool driver.

Check that node[‘driver_info’] contains IPMI credentials.

Parameters:task – a TaskManager instance containing the node to act on. Raises:InvalidParameterValue if required ipmi parameters are missing. Raises:MissingParameterValue if a required parameter is missing.

class ironic.drivers.modules.ipmitool.IPMIShellinaboxConsole

Bases: ironic.drivers.base.ConsoleInterface

A ConsoleInterface that uses ipmitool and shellinabox.

get_console(task)

Get the type and connection information about the console.

get_properties()

start_console(task)

Start a remote console for the node.

Parameters:task – a task from TaskManager Raises:InvalidParameterValue if required ipmi parameters are missing Raises:PasswordFileFailedToCreate if unable to create a file containing the password Raises:ConsoleError if the directory for the PID file cannot be created Raises:ConsoleSubprocessFailed when invoking the subprocess failed

stop_console(task)

Stop the remote console session for the node.

Parameters:task – a task from TaskManager Raises:ConsoleError if unable to stop the console

validate(task)

Validate the Node console info.

Parameters:task – a task from TaskManager. Raises:InvalidParameterValue Raises:MissingParameterValue when a required parameter is missing

class ironic.drivers.modules.ipmitool.VendorPassthru

Bases: ironic.drivers.base.VendorInterface

bmc_reset(*args, **kwargs)

Reset BMC with IPMI command ‘bmc reset (warm|cold)’.

Parameters:

• task – a TaskManager instance.
• http_method – the HTTP method used on the request.
• warm – boolean parameter to decide on warm or cold reset.

Raises:
