此群集上没有发生其他网络更改，
节点显示为网络分区，尽管通过vmKping测试主机与其他主机可以正常连通。
  •  节点位于 vSAN 群集分区中。
  •  VSAN 运行状况页面显示 host3 与 VC 断开连接，实际上 API 调用失败

Cause

看起来单播注册存在问题。两个节点上的单播配置存在问题。

Resolution

添加缺少的单播代理条目
esxcli vsan cluster unicastagent add -t node -u -U -a -p -i
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
