ironic.objects.volume_target module

class ironic.objects.volume_target.VolumeTarget(context=None, **kwargs)[source]

Bases: ironic.objects.base.IronicObject, oslo_versionedobjects.base.VersionedObjectDictCompat

VERSION = '1.0'
property boot_index
create(context=None)[source]

Create a VolumeTarget record in the DB.

Parameters

context – security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: VolumeTarget(context).

Raises

VolumeTargetBootIndexAlreadyExists if a volume target already exists with the same node ID and boot index

Raises

VolumeTargetAlreadyExists if a volume target with the same UUID exists

property created_at
dbapi = <oslo_db.api.DBAPI object>
destroy(context=None)[source]

Delete the VolumeTarget from the DB.

Parameters

context – security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: VolumeTarget(context).

Raises

VolumeTargetNotFound if the volume target cannot be found

classmethod get(context, ident)[source]

Find a volume target based on its ID or UUID.

Parameters
  • context – security context

  • ident – the database primary key ID or the UUID of a volume target

Returns

a VolumeTarget object

Raises

InvalidIdentity if ident is neither an integer ID nor a UUID

Raises

VolumeTargetNotFound if no volume target with this ident exists

classmethod get_by_id(context, db_id)[source]

Find a volume target based on its database ID.

Parameters
  • cls – the VolumeTarget

  • context – security context

  • db_id – the database primary key (integer) ID of a volume target

Returns

a VolumeTarget object

Raises

VolumeTargetNotFound if no volume target with this ID exists

classmethod get_by_uuid(context, uuid)[source]

Find a volume target based on its UUID.

Parameters
  • cls – the VolumeTarget

  • context – security context

  • uuid – the UUID of a volume target

Returns

a VolumeTarget object

Raises

VolumeTargetNotFound if no volume target with this UUID exists

property id
classmethod list(context, limit=None, marker=None, sort_key=None, sort_dir=None)[source]

Return a list of VolumeTarget objects.

Parameters
  • context – security context

  • limit – maximum number of resources to return in a single result

  • marker – pagination marker for large data sets

  • sort_key – column to sort results by

  • sort_dir – direction to sort. “asc” or “desc”.

Returns

a list of VolumeTarget objects

Raises

InvalidParameterValue if sort_key does not exist

classmethod list_by_node_id(context, node_id, limit=None, marker=None, sort_key=None, sort_dir=None)[source]

Return a list of VolumeTarget objects related to a given node ID.

Parameters
  • context – security context

  • node_id – the integer ID of the node

  • limit – maximum number of resources to return in a single result

  • marker – pagination marker for large data sets

  • sort_key – column to sort results by

  • sort_dir – direction to sort. “asc” or “desc”.

Returns

a list of VolumeTarget objects

Raises

InvalidParameterValue if sort_key does not exist

classmethod list_by_volume_id(context, volume_id, limit=None, marker=None, sort_key=None, sort_dir=None)[source]

Return a list of VolumeTarget objects related to a given volume ID.

Parameters
  • context – security context

  • volume_id – the UUID of the volume

  • limit – maximum number of volume targets to return in a single result

  • marker – pagination marker for large data sets

  • sort_key – column to sort results by

  • sort_dir – direction to sort. “asc” or “desc”.

Returns

a list of VolumeTarget objects

Raises

InvalidParameterValue if sort_key does not exist

property node_id
property properties
refresh(context=None)[source]

Loads updates for this VolumeTarget.

Load a volume target with the same UUID from the database and check for updated attributes. If there are any updates, they are applied from the loaded volume target, column by column.

Parameters

context – security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: VolumeTarget(context).

Raises

VolumeTargetNotFound if the volume target cannot be found

save(context=None)[source]

Save updates to this VolumeTarget.

Updates will be made column by column based on the result of self.do_version_changes_for_db().

Parameters

context – security context. NOTE: This should only be used internally by the indirection_api. Unfortunately, RPC requires context as the first argument, even though we don’t use it. A context should be set when instantiating the object, e.g.: VolumeTarget(context).

Raises

InvalidParameterValue if the UUID is being changed

Raises

VolumeTargetBootIndexAlreadyExists if a volume target already exists with the same node ID and boot index values

Raises

VolumeTargetNotFound if the volume target cannot be found
