适用场景

  • ONTAP 9
  • SMB3多通道

问题解答

  • 目标卷SMB 3.0多通道不支持将SMB会话绑定到多个节点、因此它不会在多个节点的LUN上运行。
  • SMB 3.0多通道技术报告TR-4740对此行为进行了如下说明。
    • 在ONTAP集群中、给定SVM可以在多个节点上托管LUN。在当前架构中、CIFS运行时状态(连接、会话、打开的文件等)是一种节点范围的内存状态、不会在多个节点之间共享。node1无法识别在node2上建立的CIFS会话。多通道不会更改CIFS运行时状态的范围。由于给定的CIFS会话仅对一个节点可见、因此可以允许SMB3客户端将会话绑定到仅该节点上托管的LID所建立的连接。SMB3客户端查询接口列表时、节点仅返回本地托管的LIP。
