The ironic.drivers.modules.wol Module

Ironic Wake-On-Lan power manager.

class ironic.drivers.modules.wol.WakeOnLanPower

Bases: ironic.drivers.base.PowerInterface

Wake-On-Lan Driver for Ironic

This PowerManager class provides a mechanism for controlling power state via Wake-On-Lan.

get_power_state(task)

Not supported. Get the current power state of the task’s node.

This operation is not supported by the Wake-On-Lan driver. So value returned will be from the database and may not reflect the actual state of the system.

Returns:POWER_OFF if power state is not set otherwise return the node’s power_state value from the database.

get_properties()

reboot(*args, **kwargs)

Not supported. Cycles the power to the task’s node.

This operation is not fully supported by the Wake-On-Lan driver. So this method will just try to power the task’s node on.

Parameters:task – a TaskManager instance containing the node to act on. Raises:InvalidParameterValue if parameters are invalid. Raises:MissingParameterValue if required parameters are missing. Raises:WolOperationError if an error occur when sending the magic packets

set_power_state(*args, **kwargs)

Wakes the task’s node on power on. Powering off is not supported.

Wakes the task’s node on. Wake-On-Lan does not support powering the task’s node off so, just log it.

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 parameters are invalid.

Raises:

MissingParameterValue if required parameters are missing.

Raises:

WolOperationError if an error occur when sending the magic packets

validate(task)

Validate driver.

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