--- upgrade: - | HPE LeftHand config options ``hplefthand_api_url``, ``hplefthand_username``, ``hplefthand_password``, ``hplefthand_clustername``, ``hplefthand_iscsi_chap_enabled``, and ``hplefthand_debug`` were deprecated in the Mitaka release and have now been removed. The corresponding ``hpelefthand_api_url``, ``hpelefthand_username``, ``hpelefthand_password``, ``hpelefthand_clustername``, ``hpelefthand_iscsi_chap_enabled``, and ``hpelefthand_debug`` should be used instead.
