这里可以看到网卡和IP配置是匹配,但是两台主机网卡显示顺序不一样.查看EtherChannel配置,也是正常的

这里显示xifenfei01-priv主机检测失败,报错为PRVF-4190,检查xifenfei01主机的hosts文件发现一处错误记录
xifenfei01/#vi /etc/hosts "/etc/hosts" 113 lines, 3556 characters # @(#)47 1.1 src/bos/usr/sbin/netstart/hosts, cmdnet, bos530 7/24/91 10: 00:46 # IBM_PROLOG_BEGIN_TAG # This is an automatically generated prolog. # # bos530 src/bos/usr/sbin/netstart/hosts 1.1 # # Licensed Materials - Property of IBM # # (C) COPYRIGHT International Business Machines Corp. 1985,1989 # All Rights Reserved # # US Government Users Restricted Rights - Use, duplication or # disclosure restricted by GSA ADP Schedule Contract with IBM Corp.
这里发现”00:46″是一个新行,而且是无效记录,除掉该行记录,继续runcluvfy.sh测试

除掉无效记录后,runcluvfy检查通过.OUI继续安装一切正常.
果然是由于/etc/hosts中出现无效记录,从而使得RAC安装检查无法通过,再次提醒各位安装RAC需要小心hosts文件
参考文档：PRVF-4190 Verification of the Hosts Config File Failed (Doc ID 1056025.1)
[INS-41112] Specified network interface doesnt maintain connectivity across cluster nodes. (Doc ID 1427202.1)
- 安装 ORACLE 12C 单节点RAC
- AIX常用命令之查看cpu/memory/swap/network/disk信息
- 10g rac安装注意事项
- hosts中缺少localhost.localdomain导致监听启动时间超长
- 单网卡绑定多IP导致TNS-12542等错误
- IP=FIRST作用说明
- 使用PXE刷XD
- 因域名解析导致数据库连接延迟分析
