适用于

  • NetApp ONTAP v9.16.1P3
  • NetApp AFF-C250
  • NetApp ONTAP tools for VMware vSphere v9.13P2
  • iSCSI 多路径配置
  • 具有双交换机 SAN 拓扑的环境

问题描述

  • 在计划的网络交换机维护期间,多个虚拟卷(vVols)和虚拟机文件系统(VMFS)数据存储区变得无法访问,导致多个虚拟机(VM)关闭。
  • 相关日志输出:

从 ONTAP 日志,当交换机 A 重启时:

 Sat Sep 13 22:33:11-0400 [<---->:kernel:netif.linkDown:info]: Ethernet e2a: Link down, check cable. Sat Sep 13 22:33:11-0400 [<---->:vifmgr:vifmgr.lifdown.noports:alert]: LIF iSCSI_1 (on virtual server 8), IP address <---->, currently cannot be hosted on node <---->, port e2a, or any of its failover targets, and is being marked as down.

两个节点上 e2a 和 e2b 端口的类似事件,对应于交换机重启。

从 ESXi 日志:

 2025-09-14T02:33:14.890Z vobd[2097666]: [vob.net.vmnic.linkstate.down] vmnic vmnic2 link state down 2025-09-14T02:33:26.032Z vobd[2097666]: [esx.problem.vmfs.heartbeat.timedout] <VMFS_DATASTORE_NAME> 2025-09-14T02:33:39.941Z vobd[2097666]: [vob.iscsi.connection.stopped] iScsi connection 0 stopped for vmhba64:C3:T1

所有非本地数据存储在停机时发生故障。
