在雙節點win2k8R2平臺安裝10gRAC過程中，由於安裝包是10.2.0.4，還沒有支持w2k8,所以在指定了OCR和仲裁盤開始格式化指定磁盤時，會報錯，提示找不到ocfs.sys.win2k8文件
解決方法如下：
1.Download patch 7320726 from:
https://support.oracle.com
2.Unzip the downloaded patch file and rename the following files:
ocfs.sys to ocfs.sys.w2k864
orafencedrv.sys to orafencedrv.sys.w2k8
3.Start Oracle Universal Installer as follows:
setup.exe New_Driver_Loc="<new_drv_loc>"
oracle.has.cfs:s_newOcfspath="new_drive_location"
oracle.has.crs:b_isWIN2k8="TRUE"
oracle.has.crs:s_newOcfspath="new_drive_location"
