从10.2.0.5开始，在asm磁盘中，第二个区的倒数第二个块是磁盘头的镜像，如果磁盘头损坏的时候，可以使用repair来修复，然而在之前的版本中，是没有镜像块的，如果磁盘头损坏，我们只能通过手动修改的方式来修复。
测试环境:db:10.2.0.5 os:rhel 5.8 使用多路径软件来估计磁盘组的名字
实验分两种环境：1，磁盘组中多个磁盘，2，磁盘组中只有一个磁盘
1，磁盘组中有多个磁盘
人为的清除磁盘头部分

下面查看磁盘目录的存放位置，磁盘目录中存放了所有的磁盘的信息，其实磁盘目录存放位置是固定的，最后一个磁盘文件的第3个区。

这里我们发现磁盘组一共有3个磁盘，每一个磁盘的名字，编号，大小，与加入的时候上面都有，我们直接从其它的正常的磁盘从读取一个磁盘头文件，修改下面几行内容
kfdhdb.dsknum: 2 ; 0x024: 0x0001 kfdhdb.grptyp: 1 ; 0x026: KFDGTP_EXTERNAL kfdhdb.hdrsts: 3 ; 0x027: KFDHDR_MEMBER kfdhdb.dskname: TEST_0002 ; 0x028: length=9 kfdhdb.grpname: TEST ; 0x048: length=4 kfdhdb.fgname: TEST_0002 ; 0x068: length=9 kfdhdb.capname: ; 0x088: length=0
修改完成，kfed merge /dev/mapper/asm6 asm6.txt就可以修复，
