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 your ented installation prerequisites

Supplement:

Other possible problems:

1. Make sure that the vip and public ip addresses are in the same network segment,

Ip planning 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
Rac2-priv 192.168.0.2
10.114.72.100 scan

If the vip and public Ip addresses are not in the same CIDR block, a similar problem may occur.

2. The hosts of the two nodes must be the same,

You must ping pub1, vip1, pub2, and vip2 nodes.
