​问题：​

​ ​		​ ​

​· 节点显示网络已分区，不过可以通过 vmKping ping 通其他节点​

​ ​

​· 节点处于 vSAN 群集分区中。​

​ ​

​· VSAN 运行状况页面显示 host3 从 VC 断开连接，实际上是 API 调用失败 ​

​ ​

​ ​
​ ​

​ ​

​ ​
​ ​

​原因：​

​ ​		​ ​

​看上去单播注册在这里是个问题。两个节点上缺少单播代理列表​

​ ​
​ ​

​ ​

​ ​
​ ​

​更改：​

​ ​		​ ​


​在此群集上未发生任何其他网络更改，​

​ ​
​ ​

​ ​

​ ​
​ ​

​解决方案：​

​ ​		​ ​

​添加缺少的单播代理条目​
​ ​

​ ​

​esxcli vsan cluster unicastagent add -t node -u -U -a -p -i ​
​ ​
​Then ​

​ ​


​示例：​
​ ​

​ ​

​esxcli vsan cluster unicastagent add -t node -u 57ea62b0-9df6-6532-110c-9457a55a37d0 -U true -a XX.XXX.XXX.XX-p 12321 -i vmk3​
