Oracle Rac opatch auto的时候为什么不打到Rac database home上

先交代环境： 操作系统：AIX 7.1 Oracle版本：Oracle Rac 11.2.0.3 之前打了11.2.0.3.9的补丁集，Rac装上还没正式用，所以就干脆再打到最新的11.2.0.3.11补丁集。
今日在前段时间新装的两套Rac打最新的psu，同样使用opatch auto的方式来打psu，但是其中一套Rac是连同Rac和Grid一起patch，而另一套是只patch Grid的补丁集。很郁闷，两套rac的crsconfig_params是基本一样的，两套Rac的相关配置都是我一手安装配置的，为什么会有如此多偏差？
如下是Rac和Grid一同patch的那套Rac： root@HDB01:/oraapp/oracle/backup>/oraapp/grid/gridhome/OPatch/opatch auto /install/psu -ocmrf /home/grid/grid.rsp Executing /oraapp/grid/gridhome/perl/bin/perl /oraapp/grid/gridhome/OPatch/crs/patch11203.pl -patchdir /install -patchn psu -ocmrf /home/grid/grid.rsp -paramfile /oraapp/grid/gridhome/crs/install/crsconfig_params

通过查看Mos文档：（Doc ID 1479651.1）得知，HDB中是有数据库存在的（即通过dbca等形式创建数据库的），而ODB上并没有数据库DB的存在。 ps：这时突然想起来，前段时间确实在HDB上建立过数据库，并做了一些数据迁移做测试。。。（愚钝啊）  opatch的时候oracle在发现没有数据库database注册到OCR中，因此只是patch了Grid。
如下：通过Mos提供的命令发现HDB上CRS中确实有ora.hdb.db的存在： grid@HDB01:/home/grid>crsctl stat res -p -w "TYPE = ora.database.type"|egrep ‘^NAME|^ORACLE_HOME‘  NAME=ora.hdb.db ORACLE_HOME=/oraapp/oracle/product/11.2.0/dbhome_1 ORACLE_HOME_OLD= NAME=ora.hdb.db ORACLE_HOME=/oraapp/oracle/product/11.2.0/dbhome_1 ORACLE_HOME_OLD= grid@HDB01:/home/grid>
而在ODB上，次命令下去无任何输出，查看一下/etc/oratab文件，确实未发现除ASM之外的其他数据库： grid@ODB01:/home/grid>crsctl stat res -p -w "TYPE = ora.database.type"|egrep ‘^NAME|^ORACLE_HOME‘ grid@SRMBODB01:/home/grid>
可以通过以下命令来另外给Rac patch 补丁： As root user, execute the following command: opatch auto <UNZIPPED_PATCH_LOCATION> -oh <DATABASE_HOME> -ocmrf <ocm response file>
