交换集群：收到来自合作伙伴的 PANIC 数据包
适用于
- ONTAP 9
- 集群交换机
问题描述
- 集群端口在一个或所有节点上关闭。
[Node-01: kernel:netif.linkDown:debug]: Ethernet e0c: Link down, check cable.
[Node-01: kernel:netif.linkDown:debug]: Ethernet e0d: Link down, check cable.
[Node-01: vifmgr:vifmgr.portdown:debug]: A link down event was received on node XXXXX, port e0d.
[Node-01: vifmgr:vifmgr.clus.linkdown:debug]: The cluster port e0d on node XXXXX has gone down unexpectedly.
- 这会触发 CLAM Panic，合作伙伴执行接管

- 由 ClusterSwitchHealthMonitor 后台程序 (cshmd) 触发的 AutoSupport 警报：
