asm disk 後設資料都儲存在disk header上，如果沒有備份，一旦disk header損壞，那麼asm disk 就不能mount了。所以備份asm disk header的資訊是必要的.

下面是一個兄弟的總結，記錄以下：

一、目的：
我們經常由於誤操作，比如對disk做了pvid=yes的操作，導致磁碟組的磁碟頭資訊丟失，從而不能正常
mount,導致起不來，從而影響業務。以下實驗就是為了解決上面情況，而提供的解決方法。
二、實驗環境：
作業系統：AIX 6.1
7y3A kJ us jz^ t0資料庫版本： 10.2.0.4 + + asm

三、實驗步驟：
1、生成kfed工具和讀取磁碟頭資訊：ITPUB個人空間6IR7x$|(Qj1?
1）編譯kfed，生成kfed工具：
