ironic.drivers.modules.noop_mgmt module

No-op management interface implementation.

class ironic.drivers.modules.noop_mgmt.NoopManagement(*args, **kwargs)

Bases: ManagementInterface

No-op management interface implementation.

Using this implementation requires the boot order to be preconfigured to first try PXE booting, then fall back to hard drives.

get_boot_device(task)

Get the current boot device for a node.

Provides the current boot device of the node. Be aware that not all drivers support this.

Parameters:

task – A task from TaskManager.

Raises:

MissingParameterValue if a required parameter is missing

Returns:

A dictionary containing:

boot_device:

Ahe 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()

Return the properties of the interface.

Returns:

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

get_sensors_data(task)

Get sensors data method.

Parameters:

task – A TaskManager instance.

Raises:

FailedToGetSensorData when getting the sensor data fails.

Raises:

FailedToParseSensorData when parsing sensor data fails.

Returns:

Returns a consistent format dict of sensor data grouped by sensor type, which can be processed by Ceilometer. eg,

{
  'Sensor Type 1': {
    'Sensor ID 1': {
      'Sensor Reading': 'current value',
      'key1': 'value1',
      'key2': 'value2'
    },
    'Sensor ID 2': {
      'Sensor Reading': 'current value',
      'key1': 'value1',
      'key2': 'value2'
    }
  },
  'Sensor Type 2': {
    'Sensor ID 3': {
      'Sensor Reading': 'current value',
      'key1': 'value1',
      'key2': 'value2'
    },
    'Sensor ID 4': {
      'Sensor Reading': 'current value',
      'key1': 'value1',
      'key2': 'value2'
    }
  }
}

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(task, device, persistent=False)

Set the boot device for a 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 a required parameter is missing

validate(task)

Validate the driver-specific Node deployment info.

This method validates whether the ‘driver_info’ and/or ‘instance_info’ properties of the task’s node contains the required information for this interface to function.

This method is often executed synchronously in API requests, so it should not conduct long-running checks.

Parameters:

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

Raises:

InvalidParameterValue on malformed parameter(s)

Raises:

MissingParameterValue on missing parameter(s)
