天萃荷净
模拟asm磁盘头损坏.手动修改.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
人为的清除磁盘头部分
[oracle@asm10g ~]$ dd if=/dev/zero of=/dev/mapper/asm6 bs=1024 count=1
1+0 records in
1+0 records out
1024 bytes (1.0 kB) copied, 1.6e-05 seconds, 64 MB/s
mount的时候发现disk 2丢失了.这里的编号是0开头

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

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
