CLUVFY工具（二）
如果安裝過10g以後的RAC環境，應該對這個工具並不陌生。在安裝Cluster和Database之前通常會執行runcluvfy.sh指令碼來檢查當前系統是否滿足安裝條件。
這篇介紹stage相關選項。
CLUVFY工具（一）：http://yangtingkun.itpub.net/post/468/511494
可以透過stage –list來列出所有cluvfy工具支援的部署元件：
bash-2.03$ cluvfy stage -list
USAGE:
cluvfy stage {-pre|-post}
Valid stage options and stage names are:
-post hwos : post-check for hardware and operating system
-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
其中-pre crsinst、-post crsinst和-pre dbinst都是RAC安裝常用的驗證選項：
bash-2.03$ cluvfy stage -pre crsinst -n racnode1,racnode2 -r 10gR2 -c /dev/rac/ocr -q /dev/rac/vot -osdba dba
