ncclient.operations.rpc.RPCError: «Структура YANG» обнаружила «фатальное» состояние «Операция не поддерживается в этом хранилище данных»

Я настраиваю имя хоста своего cisco XR с помощью ncclient. Но я получаю ниже RPCError-

Traceback (most recent call last):
  File "obj4.py", line 13, in <module>
    edit_result = device.edit_config(target='running',config=host_name, default_operation='merge').data_xml
  File "/usr/local/lib/python3.5/dist-packages/ncclient/manager.py", line 162, in wrapper
    return self.execute(op_cls, *args, **kwds)
  File "/usr/local/lib/python3.5/dist-packages/ncclient/manager.py", line 232, in execute
    raise_mode=self._raise_mode).request(*args, **kwds)
  File "/usr/local/lib/python3.5/dist-packages/ncclient/operations/edit.py", line 67, in request
    return self._request(node)
  File "/usr/local/lib/python3.5/dist-packages/ncclient/operations/rpc.py", line 337, in _request
    raise self._reply.error
ncclient.operations.rpc.RPCError: 'YANG framework' detected the 'fatal' condition 'Operation not supported on this datastore'

Мой код-

#!/usr/bin/env python3

from ncclient import manager

with manager.connect(host='198.51.100.1',port=830,username='netman',password='netman',hostkey_verify=False,device_params={'name':'iosxr'},allow_agent=True,look_for_keys=False) as device:

    host_name = '''<config>              
        <cli-config-data>
                  <cmd>hostname Lab9XR</cmd>
                 </cli-config-data>
                        </config>'''

    edit_result = device.edit_config(target='running',config=host_name, default_operation='merge').data_xml
    print (edit_result)

Пожалуйста, помогите решить проблему. Как включить модуль cli в хранилище данных этого устройства?
