问题解答

  •  在本示例中、NDMP客户端地址是数据管理应用程序(DMA) 152.27.4.81的IP地址。
  • NDMP客户端地址表示与 NDMP服务器建立连接的NDMP客户端的IP地址。
  • NDMP源地址 是集群上NDMP控制连接LIF的IP地址(152.27.1.187)。
  • NDMP源地址是DMA在建立初始连接时连接到的IP地址。
  • 数据服务器连接地址 会填充  NDMP服务器(在NetApp端)在成功建立NDMP数据连接后连接回的远程地址。  如果NDMP数据连接不成功、则此字段将为空。
  •  远程地址 由DMA通过名为data_connect的message_request提供。  在 NDMP调试日志中,data_connect请求类似于此示例。  在此示例中、152.27.4.81是DMA请求NDMP服务器使用的IP地址。

DEBUG:    Time_stamp=0x65c4ae18 (Feb  8 10:34:00 2024)
DEBUG:    message type=0 (NDMP4_MESSAGE_REQUEST)
DEBUG:    message_code=0x40a (NDMP4_DATA_CONNECT)
DEBUG:    reply_sequence=0 (0x0)
DEBUG:    error_code=0 (NDMP4_NO_ERR)
DEBUG:    addr_type=1 (NDMP4_ADDR_TCP)
DEBUG:    tcp_addr len=1 (0x1)
DEBUG:    tcp_addr[0] ip_addr=0xd9978fd [152.27.4.81]
DEBUG:    tcp_addr[0] port=9258
DEBUG:    tcp_addr[0] addr_env_len=0 (0x0)
DEBUG: DATA data_connect: op 1 (DATA_OP_IDLE)      

 

  • 在此 ndmp probe 示例中、从NDMP服务器到远程地址的连接成功。
  • 成功连接将建立  NDMP数据连接。
  •  数据服务器连接地址 是数据连接的DMA端。  在此示例中、152.27.4.81是  DMA为NDMP服务器请求的用于数据连接的远程地址。
  •  通常、NDMP客户端地址的IP与 DMA在data_connect请求中提供的远程地址相同。
  • 在具有多个备份服务器作为NDMP客户端的环境中、数据服务器连接地址可能与NDMP客户端地址不同、但仍与data_connect请求中DMA发送的IP地址匹配。
