ironic.drivers.modules.drac.bios module

DRAC BIOS configuration specific methods

ironic.drivers.modules.drac.bios.abandon_config(task)

Abandons uncommitted changes added by set_config

Parameters

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

Raises

DracOperationError on an error from python-dracclient.

ironic.drivers.modules.drac.bios.commit_config(task, reboot=False)

Commits pending changes added by set_config

Parameters

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

• reboot – indicates whether a reboot job should be automatically created with the config job.

Raises

DracOperationError on an error from python-dracclient.

Returns

the job_id key with the id of the newly created config job.

ironic.drivers.modules.drac.bios.get_config(node)

Get the BIOS configuration.

The BIOS settings look like:

{'EnumAttrib': {'name': 'EnumAttrib',
                'current_value': 'Value',
                'pending_value': 'New Value', # could also be None
                'read_only': False,
                'possible_values': ['Value', 'New Value', 'None']},
 'StringAttrib': {'name': 'StringAttrib',
                  'current_value': 'Information',
                  'pending_value': None,
                  'read_only': False,
                  'min_length': 0,
                  'max_length': 255,
                  'pcre_regex': '^[0-9A-Za-z]{0,255}$'},
 'IntegerAttrib': {'name': 'IntegerAttrib',
                   'current_value': 0,
                   'pending_value': None,
                   'read_only': True,
                   'lower_bound': 0,
                   'upper_bound': 65535}}

Parameters

node – an ironic node object.

Raises

DracOperationError on an error from python-dracclient.

Returns

a dictionary containing BIOS settings

The above values are only examples, of course. BIOS attributes exposed via this API will always be either an enumerated attribute, a string attribute, or an integer attribute. All attributes have the following parameters:

Parameters

• name – is the name of the BIOS attribute.

• current_value – is the current value of the attribute. It will always be either an integer or a string.

• pending_value – is the new value that we want the attribute to have. None means that there is no pending value.

• read_only – indicates whether this attribute can be changed. Trying to change a read-only value will result in an error. The read-only flag can change depending on other attributes. A future version of this call may expose the dependencies that indicate when that may happen.

Enumerable attributes also have the following parameters:

Parameters

possible_values – is an array of values it is permissible to set the attribute to.

String attributes also have the following parameters:

Parameters

• min_length – is the minimum length of the string.

• max_length – is the maximum length of the string.

• pcre_regex – is a PCRE compatible regular expression that the string must match. It may be None if the string is read only or if the string does not have to match any particular regular expression.

Integer attributes also have the following parameters:

Parameters

• lower_bound – is the minimum value the attribute can have.

• upper_bound – is the maximum value the attribute can have.

ironic.drivers.modules.drac.bios.set_config(task, **kwargs)

Sets the pending_value parameter for each of the values passed in.

Parameters

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

• kwargs – a dictionary of {‘AttributeName’: ‘NewValue’}

Raises

DracOperationError on an error from python-dracclient.

Returns

A dictionary containing the ‘is_commit_required’ key with a boolean value indicating whether commit_config() needs to be called to make the changes, and the ‘is_reboot_required’ key which has a value of ‘true’ or ‘false’. This key is used to indicate to the commit_config() call if a reboot should be performed.
