An active cluster was found during exclusive startup, restarting to join the cluster
PRCN-2050 : The requested VIP (nodename: racdg1-2, VIP name: racdg1-2-vip, network number: 1) has the same VIP name but different network number or preferred node than the registered VIP (nodename: racdg1-1, VIP name: racdg1-1-vip, network number: 1).

二节点执行root脚本报VIP的错误，无法添加vip服务到集群被纳管
查看集群状态
未发现二节点vip服务
发现是hosts文件的vip名称错误，对其进行改正
重新执行脚本
