OPatch failed with error code 73

安装Grid psu补丁，安装的过程中报下面73的错误

报错提示是opatch的版本太低，但是很显然opatch版本没问题。升级补丁要求最低的opatch版本为11.2.0.3.5，而我的opatch版本为11.2.0.3.6

查看 /u01/app/11.2.0/grid/cfgtoollogs/opatchauto2016-09-14_11-16-30.log日志：

 OPatch failed with error code 73
 
说明有很多中情况，不仅仅是因为opatch版本太低的原因。

想起这个环境，我是先安装过一次，然后把环境删掉重新安装的。
重新安装的步骤如下：
1.删掉原来的grid软件
2.安装grid
3.删掉数据库软件， 同时move移除 /u01/app/oraInventory目录 （此处是重点 ）
4.安装数据库软件

查看/u01/app/oraInventory/ContentsXML/inventory.xml 文件，只有下面一条记录：





而再看移除备份目录下的inventory.xml文件中的内容,有三条记录：







所以问题很明显，我在安装完grid之后，把inventory目录删掉这个步骤是错误的，把grid home的信息给删掉了，所以在安装的时候找不到。

处理方法，在现有的 /u01/app/oraInventory/ContentsXML/ inventory.xml  文件中增加grid home的信息
修改成如下：





再做升级时问题解决。
