一、首先介绍下kfed这个工具配置
kfed这个工具默认是没有编译的，需要手工编译
cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk ikfed
使用kfed dump出裸设备头信息，还是比较容易看懂对应的内容的
$kfed read /dev/drsk/c4t6001438007F3072900008000004A0000d0s6 > disk_header6.txt

二、asm磁盘丢失故障描述
故障环境描述：
操作系统：solaris 10
oracle组件：oracle 11g r2 rac
阵列存储：asm
故障描述：
2011-09-18，接到领导电话说：湖南数据库客户端连不上数据库，需要进行问题处理。
故障检查：
1）检查客户端tnsnames.ora文件，配置没有问题。
2）检查数据库crs服务，发现节点172.20.1.6有很多服务没有起来，于是尝试重启crs。在启动的过程中发现磁盘组ora_data_dg启动失败，报错显示asm disk "6" 丢失。
3）经常检查确认 disk "6" 在系统和阵列存储上都没有问题，可读可写可操作。
启动crs服务时，asm的报错信息如下：

ASM Health Checker found 1 new failures
诊断确定：
引起问题的原因可能是asm磁盘组的头部记录disk "6"信息发生了改变，asm磁盘组在启动时会找disk "6"改变之前的信息发现不到，磁盘组启动时报错磁盘"6"丢失。

三、使用kfed备份磁盘头部信息
1）使用kfed获取磁盘组ORA_DATA_DG number (4,6) /dev/drsk/c4t6001438007F3072900008000004A0000d0s6头部信息
$ kfed read /dev/drsk/c4t6001438007F3072900008000004A0000d0s6 > disk_header6.txt
$ cat disk_header6.txt

--通过输出对比可以看出disk 6的头部信息变成另一磁盘组DSMDB_DATA成员0002的头部信息
3）使用磁盘头部信息备份恢复disk 6的头部信息
清除磁盘头部信息
$ dd if=/dev/zero of=/dev/drsk/c4t6001438007F3072900008000004A0000d0s6 bs=4096 count=1
查看磁盘头部信息
$ kfed read /dev/rdsk/c4t6001438007F307290000800000320000d0s6
使用备份文件恢复磁盘头部信息
$ kfed read /dev/rdsk/c4t6001438007F307290000800000320000d0s6 text=disk_header6_bk.txt
再次确认磁盘头部信息
$ kfed read /dev/rdsk/c4t6001438007F307290000800000320000d0s6
