1. comment out 

   ```python
   def call_api(gateway_list, endpoint, element, http_method='put', api_vars=None):
       """
       Generic API handler to process a given request across multiple gateways
       :param gateway_list: (list)
       :param endpoint: (str) http api endpoint name to call
       :param element: (str) object to act upon
       :param http_method: (str) put or get http method
       :param api_vars: (dict) variables to pass to the api call
       :return: (str, int) string description and http status code
       """
   
       #target_state = target_ready(gateway_list)
       #if target_state.get('status') != 'OK':
       #    return ('failed, gateway(s) unavailable:'
       #            '{}'.format(target_state.get('summary'))), 503
   ```

   

2. add parameter valid

   ```python
   def call_api(gateway_list, endpoint, element, http_method='put', api_vars=None, valid=true):
   
   
   ```

   

3. 找2台服务器A,B, 只开启A的gateway, 关闭B的gateway,  修改delete/put 绑定的部分, 调用call_api(valid=false)
4. 这时候应该A服务器配置成功(需要yujiang手动检查), 另一台B没有任何变化
5. 启动另一台B服务器gateway, 看是否某个api可以出发refresh, 然后iscsi配置也同步成功(需要yujiang手动检查)
