  • NDMP 客户端地址是数据管理应用程序(DMA)的 IP 地址。 在本例中为 152.27.4.81。
  • NDMP 客户端地址表示建立到  NDMP 服务器连接的 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 在建立其初始连接时所连接的 IP 地址。
  • 数据服务器连接地址 填充为在 NDMP 数据连接成功时,NDMP 服务器(在 NetApp 端)连接回的 远程地址。 如果没有成功的 NDMP 数据连接,此字段将为空。
  •  远程地址由 DMA 在名为 DATA_CONNECT 的 MESSAGE_REQUEST 中提供。 在 NDMP 调试日志中,DATA_CONNECT 请求与本示例类似。 在本例中,152.27.4.81 是 DMA 请求 NDMP 服务器使用的 IP 地址。

DEBUG:      message type=0 (NDMP4_MESSAGE_REQUEST)

DEBUG:      tcp_addr[0] addr_env_len=0 (0x0)
DEBUG: DATA data_connect: op 1 (DATA_OP_IDLE)         

 

  • 在ndmp probe示例中,从 NDMP 服务器到远程地址的连接成功。
  • 成功的连接建立 了  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 请求 NDMP 服务器用于数据连接的 远程地址 。
  • NDMP 客户端地址 通常 与 DMA 在 DATA_CONNECT 请求中提供的远程地址为同一 IP。
  • 在具有多个充当 NDMP 客户端的备份服务器的环境中,数据服务器连接地址可以与 NDMP 客户端地址不同,但仍将与 DMA 在 DATA_CONNECT 请求中发送的 IP 地址匹配。
