查看ASM Instance pfile文件：

[oracle@aix213 dbs]$cat init+ASM.ora

*.background_dump_dest='/u01/app/oracle/admin/+ASM/bdump'

*.core_dump_dest='/u01/app/oracle/admin/+ASM/cdump'

*.instance_type='asm'

*.large_pool_size=12M

*.remote_login_passwordfile='SHARED'

*.user_dump_dest='/u01/app/oracle/admin/+ASM/udump'

asm_diskstring='/dev/rasm*'

asm_diskgroups='DATAFILE','REDO','ARCH'

错误原因：

asm_diskstring='/dev/rasm*'，此处与'/dev/rlv_data1','/dev/rlv_data2'不匹配

更改成：

asm_diskstring='/dev/r*'后，问题解决！
