class ironic.drivers.modules.ucs.power.Power

Bases: ironic.drivers.base.PowerInterface

Cisco Power Interface.

This PowerInterface class provides a mechanism for controlling the power state of servers managed by Cisco UCS Manager.

get_power_state(task, *args, **kwargs)

Get the current power state.

Poll the host for the current power state of the node.

Parameters:

UcsOperationError on error from UCS Client.

Returns:

power state. One of ironic.common.states.

get_properties()

Returns common properties of the driver.

reboot(*args, **kwargs)

Cycles the power to a node.

Parameters:

• task – a TaskManager instance.
• helper – ucs helper instance.

Raises:

Raises:

PowerStateFailure if the final state of the node is not POWER_ON.

set_power_state(*args, **kwargs)

Turn the power on or off.

Set the power state of a node.

Parameters:

• task – instance of ironic.manager.task_manager.TaskManager.

Raises:

InvalidParameterValue if an invalid power state was specified.

Raises:

MissingParameterValue if required CiscoDriver parameters are missing.

Raises:

UcsOperationError on error from UCS Client.

Raises:

PowerStateFailure if the desired power state couldn’t be set.

validate(task)
