开始安装过程一切正常，在安装CRS即将结束时需要root在两个节点上执行两个脚本，node2在执行最后一个脚本时报错，是public地址的问题，和老师PPT上描述的一样，手动执行vipca配置也一切正常，正常退出vipca后就在继续完成CRS安装的最后步骤时CRS助手报错了，“Oracle Cluster verification Utility”这项失败；

检查configToolAllCommands如下：

rac1-> cat configToolAllCommands

接着查看CRS日志：

原来是/dev/raw/raw1 is inaccessible!估计又是虚拟机的问题~~~

到此就基本定位了是OCR的问题了，并且是共享存储存在问题导致/dev/raw/raw1 is inaccessible

下面就是发挥想象力排错了，先把$ORA_CRS_HOME/bin 下所有关于ocr的命令出来研究一下....

发现有个检查ocr的命令ocrcheck，经检测，又一次验证了问题所在

[root@rac2 bin]# ./ocrcheck

后来又发现了ocrconfig，这个命令里有个-export，-import；目前node1是好的只是node2有问题，根据对RAC一知半解的概念分析OCR中的内容应该是同步的，估计在node1将OCR导出再导入到node2中应该没问题。但是从刚才的OCR检测信息看OCR还有个Version ，这么说貌似这个东西还在不停的变化中。

基于这两点考虑，决定在导入导出前将两个节点的CRS全关闭。

下面就是步骤了：

[root@rac1 bin]# ./crsctl stop crs

居然搞定了~但是个人认为一半是瞎搞，请老师再深入剖析一下吧!

此为梦游作，逻辑混乱，错别字等，请海涵！
