问题描述

升级ONTAP 后、单个节点上的集群端口将显示已降级状态：

Node: node-1

Speed(Mbps) Health

Port IPspace Broadcast Domain Link MTU Admin/Oper Status

--------- ------------ ---------------- ---- ---- ----------- --------

e4a Cluster Cluster up 9000 auto/40000 degraded

此外、在EMS日志中还会显示类似于以下内容的消息：

[node-1: vifmgr: vifmgr.cluscheck.ctdpktloss:alert]: Continued packet loss when pinging from cluster lif node-1_clus1 (node node-1) to cluster lif node-2_clus1 (node node-2)
