在双节点win2k8R2平台安装10gRAC过程中，由于安装包是10.2.0.4，还没有支持w2k8,所以在指定了OCR和仲裁盘开始格式化指定磁盘时，会报错，提示找不到ocfs.sys.win2k8文件

解决方法如下：

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=""
oracle.has.cfs:s_newOcfspath="new_drive_location"
oracle.has.crs:b_isWIN2k8="TRUE"
oracle.has.crs:s_newOcfspath="new_drive_location"
