Redfish module.

exception spicerack.redfish.RedfishError[source]¶

Bases: SpicerackError

General errors raised by this module.

exception spicerack.redfish.RedfishTaskNotCompletedError[source]¶

Bases: RedfishError

Raised when a Redfish task is not found on the server.

class spicerack.redfish.ChassisResetPolicy(value)[source]¶

Bases: Enum

Subset of available Chassis.Reset policies compatible with all supported vendors (at this moment only Dell).

FORCE_OFF: str = 'ForceOff'¶: Turn off the unit immediately (nongraceful shutdown).

FORCE_RESTART: str = 'ForceRestart'¶: Shut down immediately and nongracefully and restart the system.

GRACEFUL_RESTART: str = 'GracefulRestart'¶: Shut down gracefully and power on.

GRACEFUL_SHUTDOWN: str = 'GracefulShutdown'¶: Shut down gracefully and power off.

ON: str = 'On'¶: Turn on the unit.

class spicerack.redfish.DellSCP(config: dict, target: spicerack.redfish.DellSCPTargetPolicy, *, allow_new_attributes: bool = False)[source]¶

Bases: object

Represent a Dell System Configuration Profile configuration as returned by Redfish API.

Parse the Redfish API response.

Parameters:

config (dict) -- the configuration as returned by Redfish API.
target (spicerack.redfish.DellSCPTargetPolicy) -- describe which sections of the configuration are represented in the loaded configuration.
allow_new_attributes (bool, default: False) -- when set to True it allows the creation of new attributes not already present in the provided configuration that otherwise would raise an exception. This is useful for example when changing the boot mode between Uefi and Bios that changes the keys present.

empty_components() → None[source]¶

Empty the current Components from the configuration, allowing to create a new configuration from scratch.

After calling this method is possible to set values for non-existing components that would otherwise raise an exception.

Return type:: None

set(component_name: str, attribute_name: str, attribute_value: str) → bool[source]¶

Update the current configuration setting to the new value for the given key in the given component.

Notes

This updates only the instance representation of the instance. To push and apply the changes to the server see spicerack.redfish.RedfishDell.scp_push(). In order to add attributes not present the instance must have been created with allow_new_attributes set to True or the spicerack.redfish.DellSCP.empty_component() method called. This last one allows to automatically create any missing component while setting attributes.

Parameters:

component_name (str) -- the name of the component the settings belongs to.
attribute_name (str) -- the attribute name whose value needs to be updated.
attribute_value (str) -- the new value for the attribute to set.

Return type:

bool

Returns:

True if the value was added or changed, False if it had already the correct value.

Raises:

spicerack.redfish.RedfishError -- if unable to find the given component or attribute and the creation of new
items is not allowed. --

update(changes: dict[str, dict[str, str]]) → bool[source]¶

Bulk update the current configuration with the set of changes provided.

Notes

This updates only the instance representation of the instance. To push and apply the changes to the server see spicerack.redfish.RedfishDell.scp_push().

Parameters:: changes (dict[str, dict[str, str]]) -- a dictionary of changes to apply in the same format of the one returned by spicerack.redfish.DellSCP.components().
Return type:: bool
Returns:: True if any of the values produced a change, False if no change was made.
Raises:: spicerack.redfish.RedfishError -- if unable to apply all the changes.
