该环境为本人测试环境，生产环境该方案仍可使用。
一、服务器上添加新存储，根据原来的裸设备绑定方式对裸盘进行绑定。
KERNEL=="sd*", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="1ATA_VBOX_HARDDISK_VB74b34d9d-2af737fa", NAME="newasm-diskb", OWNER="grid", GROUP="asmadmin", MODE="0660"
这里使用的是scsi_id进行绑定的，因此新加的盘也使用该方法。
验证新存储绑定状态：
[root@hadoop01 rules.d]# ll /dev/new*
brw-rw----. 1 grid asmadmin 8, 32 Jul 26 11:32 /dev/newasm-diskb
老存储绑定状态：
[root@hadoop01 rules.d]# ll /dev/asm*
brw-rw----. 1 grid asmadmin 8, 16 Jul 26 11:34 /dev/asm-diskb
二、grid用户asmca创建磁盘组
newdata为新增的磁盘组。
三、迁移spfile&控制文件
3.1 srvctl stop database -d orcl关闭数据库。
3.2 添加控制文件到相应路径
先nomount数据库：
SQL> startup nomount;
ORACLE instance started.
Total System Global Area 1603411968 bytes
Fixed Size 2228784 bytes
Variable Size 1090522576 bytes
Database Buffers 503316480 bytes
Redo Buffers 7344128 bytes
然后：
[oracle@hadoop01 ~]$ rman target /
Recovery Manager: Release 11.2.0.3.0 - Production on Tue Jul 26 17:15:43 2016
Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.
connected to target database: ORCL (not mounted)
RMAN> restore controlfile to '+NEWDATA' from '+data/orcl/controlfile/Current.260.918213121';
Starting restore at 26-JUL-16
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=36 instance=orcl1 device type=DISK
channel ORA_DISK_1: copied control file copy
Finished restore at 26-JUL-16
RMAN> restore controlfile to '+NEWDATA' from '+data/orcl/controlfile/Current.260.918213121';
Starting restore at 26-JUL-16
using channel ORA_DISK_1
channel ORA_DISK_1: copied control file copy
Finished restore at 26-JUL-16
3.3 创建pfile，并修改其部分内容
SQL> create pfile='/home/oracle/initorcl.ora' from spfile;
File created.
修改控制文件位置：
*.control_files='+DATA/orcl/controlfile/current.261.918213119','+DATA/orcl/controlfile/current.260.918213121'
修改创建数据文件默认位置：
*.db_create_file_dest='+DATA'
修改快速回复区路径：
*.db_recovery_file_dest='+DATA'
如仍存在包含老磁盘组的参数一并修改掉。
修改完成的结果如下：
orcl1.__db_cache_size=503316480
orcl2.__db_cache_size=587202560
orcl1.__java_pool_size=16777216

*.db_recovery_file_dest_size=104856551424

*.remote_login_passwordfile='exclusive'
orcl2.thread=2
orcl1.thread=1
orcl1.undo_tablespace='UNDOTBS1'
orcl2.undo_tablespace='UNDOTBS2'
3.4 在rac中的一个节点（此处用一号结点）指定pfile启动数据库到mount状态以验证pfile正确定，创建spfile。
SQL> startup force mount pfile='/home/oracle/initorcl.ora';
ORACLE instance started.
Total System Global Area 1603411968 bytes
Fixed Size 2228784 bytes
Variable Size 1090522576 bytes
Database Buffers 503316480 bytes
Redo Buffers 7344128 bytes
Database mounted.
mount成功，创建spfile
SQL> create spfile='+newdata/orcl/spfileorcl.ora' from pfile='/home/oracle/initorcl.ora';
File created.
3.5 srvctl修改数据库参数文件位置。
[oracle@hadoop01 ~]$ srvctl modify database -d orcl -p +newdata/orcl/spfileorcl.ora
[oracle@hadoop01 ~]$ srvctl config database -d orcl
Database unique name: orcl
Database name: orcl
Oracle home: /u01/app/oracle/product/11.2.0/dbhome_1
Oracle user: oracle
Spfile: +newdata/orcl/spfileorcl.ora

Database role: PRIMARY
Management policy: AUTOMATIC
Server pools: orcl
Database instances: orcl1,orcl2
Disk Groups: DATA,NEWDATA
Mount point paths:
Services:
Type: RAC
Database is administrator managed
3.6 关闭数据库用新的spfile以及controlfile启动一遍，验证正确性。
[oracle@hadoop01 ~]$ srvctl start database -d orcl
[oracle@hadoop01 ~]$
[oracle@hadoop01 ~]$ sqlplus / as sysdba

四、迁移数据文件
保证数据库处于归档模式。rman进行backup as copy 操作
[oracle@hadoop01 ~]$ rman target /

srvctl stop database -d orcl -o immediate
[oracle@hadoop01 ~]$ srvctl stop database -d orcl -o immediate
[oracle@hadoop01 ~]$ sqlplus / as sysdba

SQL> Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
Data Mining and Real Application Testing options
[oracle@hadoop01 ~]$ rman target /
Recovery Manager: Release 11.2.0.3.0 - Production on Tue Jul 26 17:36:28 2016
Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.
connected to target database: ORCL (DBID=1445993855, not open)
RMAN> switch database to copy;
using target database control file instead of recovery catalog
datafile 1 switched to datafile copy "+NEWDATA/orcl/datafile/system.260.918235957"
datafile 2 switched to datafile copy "+NEWDATA/orcl/datafile/sysaux.261.918235981"
datafile 3 switched to datafile copy "+NEWDATA/orcl/datafile/undotbs1.263.918236023"

datafile 6 switched to datafile copy "+NEWDATA/orcl/datafile/undotbs2.264.918236029"
RMAN>
switch完成后一定要recover一下
[oracle@hadoop01 ~]$ rman target /
Recovery Manager: Release 11.2.0.3.0 - Production on Tue Jul 26 17:40:51 2016
Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.
connected to target database: ORCL (DBID=1445993855, not open)
RMAN> recover database;
Starting recover at 26-JUL-16
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=35 instance=orcl1 device type=DISK
starting media recovery
media recovery complete, elapsed time: 00:00:02
Finished recover at 26-JUL-16
RMAN> exit
Recovery Manager complete.
然后srvctl方式启动数据库。
[oracle@hadoop01 ~]$ srvctl start database -d orcl
五、迁移临时文件
查看临时表空间
select * from dba_tablespaces where contents = 'TEMPORARY';
查看临时文件
select * from V$TEMPFILE;
为临时表空间添加临时文件
SQL> alter tablespace temp add tempfile size 18M;
Tablespace altered.
由于db_create_file_dest参数设置为+newdata，所以新临时文件会自动创建在newdata磁盘组上
删除老存储上的临时文件。
[oracle@hadoop01 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Tue Jul 26 17:50:16 2016
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
Data Mining and Real Application Testing options
SQL> alter tablespace temp add tempfile size 18M;
Tablespace altered.
SQL> ALTER DATABASE TEMPFILE '+DATA/orcl/tempfile/temp.266.918213143' DROP INCLUDING DATAFILES;
Database altered.
六、迁移online redo log
ALTER DATABASE ADD LOGFILE THREAD 1 GROUP 5 SIZE 50M;
ALTER DATABASE ADD LOGFILE THREAD 1 GROUP 6 SIZE 50M;
ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 7 SIZE 50M;
ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 8 SIZE 50M;
ALTER DATABASE DROP LOGFILE GROUP 1;
ALTER DATABASE DROP LOGFILE GROUP 2;
ALTER DATABASE DROP LOGFILE GROUP 3;
ALTER DATABASE DROP LOGFILE GROUP 4;
遇到在线日志或未回档的日志采用如下命令：
alter system switch logfile;
alter system checkpoint;
七、迁移OCR&voting disk&ASM spfile
[root@hadoop01 ~]# crsctl query css votedisk
## STATE File Universal Id File Name Disk group
-- ----- ----------------- --------- ---------
1. ONLINE 4b1a5effbe514f46bfd6a45c20c06935 (/dev/asm-diskb) [DATA]
Located 1 voting disk(s).
[root@hadoop01 ~]# crsctl replace votedisk +newdata
Successful addition of voting disk 350eddf550034f2bbfb890dd05d80ed0.
Successful deletion of voting disk 4b1a5effbe514f46bfd6a45c20c06935.
Successfully replaced voting disk group with +newdata.
CRS-4266: Voting file(s) successfully replaced
[root@hadoop01 ~]# crsctl query css votedisk
## STATE File Universal Id File Name Disk group
-- ----- ----------------- --------- ---------
1. ONLINE 350eddf550034f2bbfb890dd05d80ed0 (/dev/newasm-diskb) [NEWDATA]
Located 1 voting disk(s).
voting disk 迁移完成。
[root@hadoop01 ~]# ocrcheck

如遇到CRS-4602，CRS-1638 错误，传送门-->http://blog.csdn.net/u011478909/article/details/51972303
SQL> create pfile='/tmp/pfile.asm' from spfile;
File created.
SQL> create spfile='+NEWDATA' from pfile='/tmp/pfile.asm';
File created.
八、卸载老磁盘组
asmca dismount +data磁盘组 然后将其drop
至此，oracle rac存储更换完成
