--- fixes: - | The `ironic-python-agent `_ version 3.5.0 contains a fix that allows multi-device objects to be selected as a root disk. These devices MAY be created automatically in the case of some ATARAID controllers with pre-existing configuration, or via the actions of a custom hardware manager. Operators who require this functionality are encouraged to ensure that their deployment ramdisks are up to date. See `story 2003445 `_ for more information.
