ironic.drivers.modules.agent_power module

The agent power interface.

class ironic.drivers.modules.agent_power.AgentPower(*args, **kwargs)[source]

Bases: PowerInterface

Power interface using the running agent for power actions.

get_power_state(task)[source]

Return the power state of the task’s node.

Essentially, the only known state is POWER ON, everything else is an error (or more precisely None).

Parameters:

task – A TaskManager instance containing the node to act on.

Returns:

A power state. One of ironic.common.states.

get_properties()[source]

Return the properties of the interface.

Returns:

dictionary of <property name>:<property description> entries.

get_supported_power_states(task)[source]

Get a list of the supported power states.

Only contains REBOOT.

Parameters:

task – A TaskManager instance containing the node to act on.

Returns:

A list with the supported power states defined in ironic.common.states.

reboot(task, timeout=None)[source]

Perform a reboot of the task’s node.

Only soft reboot is implemented.

Parameters:

  • task – A TaskManager instance containing the node to act on.

  • timeout – timeout (in seconds) positive integer (> 0) for any power state. None indicates to use default timeout.

set_power_state(task, power_state, timeout=None)[source]

Set the power state of the task’s node.

Parameters:

  • task – A TaskManager instance containing the node to act on.

  • power_state – Power state from ironic.common.states. Only REBOOT and SOFT_REBOOT are supported and are synonymous.

  • timeout – timeout (in seconds) positive integer (> 0) for any power state. None indicates to use default timeout.

Raises:

PowerStateFailure on non-supported power state.

supports_power_sync(task)[source]

Check if power sync is supported for the given node.

Not supported for the agent power since it is not possible to power on/off nodes.

Parameters:

task – A TaskManager instance containing the node to act on with a shared lock.

Returns:

boolean, whether power sync is supported.

validate(task)[source]

Validate the driver-specific Node deployment info.

Parameters:

task – A TaskManager instance containing the node to act on.

Raises:

InvalidParameterValue on malformed parameter(s)
