cluvfy作为集群验证工具在Oracle集群和RAC安装和配置的过程中可以起到非常好的辅助作用，简单看一下这个工具带给我们的功能。
1.获取集群验证工具cluvfy的帮助信息
RACDB1@rac1 /home/oracle$ cluvfy -help
USAGE:
cluvfy [ -help ]
cluvfy stage { -list | -help }
cluvfy stage {-pre|-post} <stage-name> <stage-specific options> [-verbose]
cluvfy comp { -list | -help }
cluvfy comp <component-name> <component-specific options> [-verbose]
本文主要介绍一下有关stage类型的验证方法。
Oracle集群和RAC安装过程中每个阶段都称作一个stage，进入每一个stage之前和之后都应该做检查。在进入特定阶段之前应进行一系列的预定义内容的检查，确保集群环境已满足进入下一阶段的条件，即所谓的“预检查”。与之对应的便是“后期检查”，即在完成某个阶段操作后需要执行的一组预定义的检查动作。
2.获得stage选项可验证的信息
可以使用“cluvfy stage -list”命令获得可验证的阶段。
RACDB1@rac1 /home/oracle$ cluvfy stage -list
USAGE:
cluvfy stage {-pre|-post} <stage-name> <stage-specific options> [-verbose]
Valid stage options and stage names are:
-post hwos : post-check for hardware and operating system
-pre cfs : pre-check for CFS setup
-post cfs : post-check for CFS setup
-pre crsinst : pre-check for CRS installation
-post crsinst : post-check for CRS installation
-pre dbinst : pre-check for database installation
-pre dbcfg : pre-check for database configuration
简单的注释：
-post hwos：对硬件和操作系统进行后期检查；
-pre cfs：对CFS设置进行预检；
-post cfs：对CFS设置进行后期检查；
-pre crsinst：对CRS安装进行预检查；
-post crsinst：对CRS安装进行后期检查；
-pre dbinst：对数据库安装进行预检查；
-pre dbcfg：对数据库配置进行预检查。
