适用场景

  • ONTAP 9
  • SnapMirror

问题描述

  • 驻留在一个节点上的卷的SnapMirror失败、并显示以下错误。
Failed to create snapshot snapmirror.e180b5b4-896a-11e8-a2cf-00a098d93948_2162351280.2025-03-31_123500 on volume SVM:vol. (CSM: Connection aborted.)
  • 集群对等方处于部分状态、无法访问有问题的节点。

  • 托管IC LIF的所有集群端口均为管理端口/操作端口"已启动"
  • 此端口上的L2 ping命令用于确认问题描述是在L2还是L3网络上、但未在同一网络上发现响应。
  • 捕获数据包跟踪以确认没有从交换机收到对所发送ARP请求的响应。

  • 端口状态显示传输时端口上报告了大量丢弃、这表示交换机不接受数据包。

  • 网络团队已验证端口配置并未发现问题、但已确认交换机端口未收到任何数据包。
