分析

MOS文档:TOP Note: Solutions for Typical Grid Infrastructure/RAC Database runInstaller Issues (文档 ID 1056713.1)

P: [INS-40724] No locally defined network interface matches the SCAN VIP subnet.
S: Public IP and SCAN VIP should be in same subnet, and public IP should be primary IP on a NIC.

从网卡返回信息来看，10.252.177网段和192.168.100网段在同一块网卡上面，由于这个环境原来是从生产环境下线的服务器用来安装UAT数据库用的，将192.168.100多余的IP删掉，将私网192.168.100配置到en5网卡上
