Oracle 11.2.0.4 + rhel 6.5 x64一个神奇的问题

1、集群状态
（应该使用grid$ crsctl stat res -t，因看起来比较直观，临时使用如下命令）

[grid@rac1 rac1]$ crs_stat -t
Name Type Target State Host

2、votedisk /dev/raw/raw3 被误dd操作，结果OFFLINE





ASMCA无法看到ASM磁盘组信息：



3、此时查看v$asm_disk报错如下
SQL> show parameter inst

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

cluster_database_instances integer 4

instance_name string +ASM1

instance_number integer 1

instance_type string asm

SQL> select PATH from v$asm_disk;

select PATH from v$asm_disk

*

ERROR at line 1:

ORA-00600: internal error code, arguments: [kfdskResolveDisk1], [], [], [], [],

[], [], [], [], [], [], []

查询MOS无解：



4、启动数据库报错如下，查询MOS无解
SQL> startup

ORACLE instance started.

此次故障暂时无解。。。
