DATA  是一个dg（NORMAL）。里面有两个磁盘 DATA_0001  DATA_0002 分别来自两个存储
有两个failgroup DATA_0001 DATA_0000  每个里面都只有一个磁盘。
上面看起来很正常

当一个存储断电上面有磁盘DATA_0002.
出现如下情况，

QL> select group_number,disk_number,total_mb,free_mb,name,failgroup,path,mount_status,state,mode_status,REDUNDANCY from v$asm_disk  order by  group_number,disk_number,failgroup,path,mount_status,state,mode_status,REDUNDANCY;
