报错描述：

select a.group_number,b.name,a.failgroup,a.path
from v$asm_disk a,v$asm_diskgroup b
where a.group_number=b.group_number
and a.group_number=1
order by 3;

ERROR at line 1:
ORA-15032: not all alertations performed
ORA-15411: Failure groups in disk group DATA have different number of disks.

从报错信息得知，要求每个failgroup中磁盘数量一致，可通过修改ASM隐含参数来解决：

SQL> alter system set "_asm_disable_failgroup_size_checking"=true;

System altered.

SQL> alter system set "_asm_disable_dangerous_failgroup_checking"=true;

System altered.

SQL> alter diskgroup data add failgroup DATA001 disk '/dev/data06';

System altered.
