這里可以看到網卡和IP配置是匹配,但是兩臺主機網卡顯示順序不一樣.查看EtherChannel配置,也是正常的

這里顯示xifenfei01-priv主機檢測失敗,報錯為PRVF-4190,檢查xifenfei01主機的hosts文件發現一處錯誤記錄

xifenfei01/#vi /etc/hosts
"/etc/hosts" 113 lines, 3556 characters

這里發現”00:46″是一個新行,而且是無效記錄,除掉該行記錄,繼續runcluvfy.sh測試

除掉無效記錄后,runcluvfy檢查通過.OUI繼續安裝一切正常.
果然是由于/etc/hosts中出現無效記錄,從而使得RAC安裝檢查無法通過,再次提醒各位安裝RAC需要小心hosts文件
