asm中怎样终止正在reblance的磁盘操作？

背景：公司新买了一套存储，准备替换。方法是通过加磁盘，剔除磁盘的方式操作。加盘时，发现盘的读写速度很慢。数据库性能明显下降
sql> alter diskgroup test add disk '/dev/mapper/asmnetappdata01p1' rebalance power 5;

asm中怎样终止正在添加的磁盘操作？
1.将正在进行reblance的磁盘终止reblance
SQL> alter diskgroup <TEST> rebalance power 0;     -----终止磁盘的reblance
Diskgroup altered.

SQL> select * from gv$asm_operation          ----检查磁盘是否终止reblance

INST_ID GROUP_NUMBER OPERA PASS STAT POWER ACTUAL SOFAR EST_WORK EST_RATE EST_MINUTES ERROR_CODE CON_ID
---------- ------------ ----- --------- ---- ---------- ---------- ---------- ---------- ---------- ----------- -------------------------------------------- ----------

2 1 REBAL REBALANCE WAIT 0 0
2 1 REBAL REBUILD WAIT 0 0

2.手动删除正在添加的磁盘
SQL> select NAME,MOUNT_STATUS,HEADER_STATUS,MODE_STATUS ,STATE,REDUNDANCY,TOTAL_MB,FREE_MB,PATH from v$asm_disk;
NAME MOUNT_S HEADER_STATU MODE_ST STATE REDUNDA TOTAL_MB FREE_MB PATH

3.删除正在添加的磁盘。
SQL> ALTER DISKGROUP TEST DROP DISK NETAPP0001 REBALANCE POWER 15 WAIT;
SQL>

查看删盘的进度：

SQL> select name,OS_MB,TOTAL_MB,FREE_MB,TOTAL_MB-FREE_MB from v$asm_disk_stat;

NAME OS_MB TOTAL_MB FREE_MB TOTAL_MB-FREE_MB
