10205以下需要使用kfed或者dd命令备份asm disk header
asm disk 元数据都保存在disk header上，如果没有备份，一旦disk header损坏，那么asm disk 就不能mount了。所以备份asm disk header的信息是必要的.
下面是一个兄弟的总结，记录以下：

我们经常由于误操作，比如对disk做了pvid=yes的操作，导致磁盘组的磁盘头信息丢失，从而不能正常
mount,导致数据库起不来，从而影响业务。以下实验就是为了解决上面情况，而提供的解决方法。
二、实验环境：
操作系统：AIX 6.1
ITPUB个人空间5[k"a*Qz;J{q
