‘/dev/oracleasm/disks/DATA009‘ rebalance power 0;

SQL>select group_number,name ,path from v$asm_disk;
GROUP_NUMBER NAME PATH
------------ ------------- ------------------------------
1 ARCH_0003 /dev/oracleasm/disks/ARCH004
1 ARCH_0002 /dev/oracleasm/disks/ARCH003
1 ARCH_0005 /dev/oracleasm/disks/ARCH006
1 ARCH_0004 /dev/oracleasm/disks/ARCH005
1 ARCH_0007 /dev/oracleasm/disks/DATA014
1 ARCH_0006 /dev/oracleasm/disks/DATA013
1 ARCH_0011 /dev/oracleasm/disks/DATA018
1 ARCH_0010 /dev/oracleasm/disks/DATA017
1 ARCH_0009 /dev/oracleasm/disks/DATA016
1 ARCH_0008 /dev/oracleasm/disks/DATA015
······

其中存储工程师帮忙提供的存储DATA*是提供给DATA磁盘组使用的，因此存在问题。

删除磁盘命令

alter diskgroup arch drop disk ‘ARCH_0006‘ rebalance power 0;
alter diskgroup arch drop disk ‘ARCH_0007‘ rebalance power 0;
alter diskgroup arch drop disk ‘ARCH_0008‘ rebalance power 0;
alter diskgroup arch drop disk ‘ARCH_0009‘ rebalance power 0;
alter diskgroup arch drop disk ‘ARCH_0010‘ rebalance power 0;
alter diskgroup arch drop disk ‘ARCH_0011‘ rebalance power 0;
此时删除成功，但是视图查询ARCH磁盘还在！！！需要重平衡。

alter diskgroup arch rebalance power 6;

再次查询视图

SQL>select group_number,name ,path from v$asm_disk;

SQL>select group_number,name ,path from v$asm_disk;
GROUP_NUMBER NAME PATH

/dev/oracleasm/disks/DATA014

/dev/oracleasm/disks/DATA018
/dev/oracleasm/disks/DATA017
/dev/oracleasm/disks/DATA016
/dev/oracleasm/disks/DATA015
