适用场景

  • ONTAP 9
  • 类似于UNIX或UNIX的操作系统
  • NFSv3

问题解答

  • 客户端请求NLM锁定、并将请求发送到端口4045上的ONTAP。
  • 如果无法立即授予阻止锁定、则在授予锁定后、ONTAP 将向客户端发送回调。
  • 将使用使用端口映射程序发现的端口从ONTAP 回调到客户端。
  • 表示NLM正在被阻止的数据包跟踪小程序:
1478 2022-08-04 07:07:34.920384 xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx NLM V4 LOCK Call (Reply In 1479) FH:0x91a3284f 1479 2022-08-04 07:07:34.920835 xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx NLM V4 LOCK Reply (Call In 1478) NLM_BLOCKED
  • 用于确认客户端使用的端口的数据包跟踪记录:
