Oracle ASM错误之--ORA-15033

Oracle ASM错误之--ORA-15033

系统环境：

操作系统： AIX 5.3.8

Oracle： Oracle 10gR2

故障现象：

SQL> create diskgroup datafile  2      normal redundancy    failgroup fg1 disk '/dev/rlv_data1'  3    4    failgroup fg2 disk '/dev/rlv_data2';create diskgroup datafile*ERROR at line 1:ORA-15018: diskgroup cannot be createdORA-15033: disk '/dev/rlv_data2' belongs to diskgroup "RECOVER"ORA-15033: disk '/dev/rlv_data1' belongs to diskgroup "DATA"SQL> select group_number,name,state from v$asm_diskgroup;GROUP_NUMBER NAME                           STATE------------ ------------------------------ -----------           0 REDO                           DISMOUNTED           0 ARCH                           DISMOUNTED           0 DATA                           DISMOUNTED           0 RECOVER                        DISMOUNTED

故障原因：

应该是在AIX的ODM中，rlv_data1和rlv_data2，已经属于另外的磁盘组。

解决方法：

1）清理raw头部信息

[root@aix213 /]#dd if=/dev/zero of=/dev/rlv_data1 bs=8k count=256256+0 records in256+0 records out[root@aix213 /]#dd if=/dev/zero of=/dev/rlv_data2 bs=8k count=256256+0 records in256+0 records out

2）重新建立ASM DISKGROUP

[oracle@aix213 dbs]$sqlplus / as sysdbaSQL*Plus: Release 10.2.0.1.0 - Production on Thu Jul 24 11:44:29 2014Copyright (c) 1982, 2005, Oracle.

3）验证

SQL> select name ,state from v$asm_diskgroup;NAME                           STATE------------------------------ -----------REDO                           DISMOUNTEDARCH                           DISMOUNTEDDATAFILE                       MOUNTEDSQL> alter diskgroup redo mount;Diskgroup altered.SQL> alter diskgroup arch mount;Diskgroup altered.SQL> select name ,state from v$asm_diskgroup;NAME                           STATE------------------------------ -----------REDO                           MOUNTEDARCH                           MOUNTEDDATAFILE                       MOUNTED

@至此，问题被解决 ！
