问题描述

如果将集群LUN迁移到更新后的交换机、 cluster ping-cluster 则会显示路径已损坏。4个节点的示例：

::> set advanced

::*> cluster ping-cluster -node node_name-2

Host is node_name-2

Getting addresses from network interface table...

Cluster node_name-2_clus1 169.254.97.141 node_name-2 e4a

Cluster node_name-2_clus2 169.254.119.137 node_name-2 e4e

...

Basic connectivity succeeds on 6 path(s)

Basic connectivity fails on 6 path(s)

...

Larger than PMTU communication succeeds on 6 path(s)

RPC status:

6 paths up, 0 paths down (tcp check)

6 paths up, 0 paths down (udp check)

每个节点都会报告类似以下内容的错误：

[node_name-1: vifmgr: vifmgr.cluscheck.droppedall:debug]: Total packet loss when pinging from cluster lif node_name-1_clus2 (node node_name-1) to cluster lif node_name-2_clus1 (node node_name-2). [node_name-1: vifmgr: callhome.clus.net.degraded:debug]: Call home for CLUSTER NETWORK DEGRADED: Total Packet Loss - Ping failures detected between node_name-1_clus1 ( 169.254.243.146 ) on node_name-1 and node_name-2_clus2 ( 169.254.43.139 ) on node_name-2

cluster ping-cluster 端口对连接到其他交换机的其他端口执行ping操作时失败。
cluster ping-cluster 端口对连接到同一交换机的其他端口执行ping操作时正常。
