因为第17步恢复的的datadg磁盘组,IO测试工具没有把/dev/raw/raw3磁盘所自动备份的磁盘头信息给破坏

第8步,重建了CRSDG磁盘组后,不可以直接执行:kfed repairt /dev/raw/raw1?也就是,第9步的意义何在?
还是说,kfed 操作必须是在 CRS磁盘组 正常的情况下,才能执行,当 crs磁盘组 故障时,得用这命令:

./crsctl replace votedisk +CRSDG

第9步的意义是查看自动备份的ocr文件,因为文件每四个小时备份一次,还原时要指定备分文件名
重建crsdg磁盘组后,只能使用备份的ocr文件来还原

第13步,是ASM的日志文件中显示了操作信息,因为磁盘组不能mount ,asm实例选择的重建操作,是日志记录,我不是的恢复操作记录。
