今天有个朋友在AIX平台下面安装11.2.0.2 RAC，AIX系统的版本是61000604,使用了HACMP 6.1双机软件。
在安装cluster的时候，在2节点执行root.sh的时候报下面的错误：
- # /oracle/app/11.2.0/grid/root.sh
- Running Oracle 11g root script...
- The following environment variables are set as:
- ORACLE_OWNER= grid
- ORACLE_HOME= /oracle/app/11.2.0/grid

当时分析原因如下：
1，有部分的包没有安装
2，没有执行rootpre.sh或者没有把grid用户增加到HA的组中。
在朋友那里了解情况后，是因为他在安装的时候只在1节点上面执行了rootpre.sh，没有在2节点上面执行。
解决方案：
在2节点上面执行rootpre.sh脚本，增加按照提示，把grid用户增加到ha组中，
删除后root.sh配置的信息，再次执行root.sh，一切正常。
