your 'Private' network adapter listed second in your binding order on all cluster nodes.
SOLUTION
Fix the Network Adapter Binding order so that the public network adapter is listed first and
your private network adapter is listed second as per documented installation prerequisites
补充：
其他可能存在的问题：
1.》确保 vip 和public ip 在同一个网段内，
ip 规划 eg：
10.114.72.83 rac1
10.114.72.84 rac1-vip
192.168.0.1 rac1-priv
10.114.72.85 rac2
10.114.72.86 rac2-vip
192.168.0.2 rac2-priv
10.114.72.100 scan
如果vip 和 public Ip 不在同一个网段里局会出现类似的问题。
2》。两个节点的hosts 要一样，
并且 ping pub1 ，vip1 ，pub2，vip2 两个节点要能ping 通
