How to move ASM spfile to a different disk group [ID 1082943.1]
适用于11R2
有两种方法：采用create pfile/spflie通过中间文件迁移；适用asmcmd自带的spcopy命令；
第一种方法比较简单，步骤如下
create pfile='/tmp/pfile+ASM.ora' from spfile;
create spfile='+PLAY' from pfile='/tmp/pfile+ASM.ora';
crsctl stop has
crsctl start has --重启验证

下面介绍一下spcopy命令
由于GPnP profile记录有spfile路径信息，因此需添加-u选项自动更新

1. Copy spfile with -u option - to update GPnP profile in RAC environment
$ asmcmd spget
+DATA/asm/asmparameterfile/registry.253.722601213

$ asmcmd lsdg
State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Votin g_files Name
MOUNTED EXTERN N 512 4096 1048576 14658 9814 0 9814 0 N DATA/
MOUNTED EXTERN N 512 4096 1048576 9772 8507 0 8507 0 N PLAY/
MOUNTED EXTERN N 512 4096 1048576 9772 9212 0 9212 0 N RECO/

$ asmcmd spcopy -u +DATA/asm/asmparameterfile/registry.253.722601213 +PLAY/spfileASM.ora

2. Restart the HA stack to verify that ASM starts up fine with copiedspfile
$ crsctl stop has
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on '<server>'
...
CRS-4133: Oracle High Availability Services has been stopped.

$ crsctl start has
CRS-4123: Oracle High Availability Services has been started.

$ asmcmd spget
+PLAY/spfileASM.ora

3. Remove the original spfile
$ asmcmd ls -l +DATA/asm/asmparameterfile
Type Redund Striped Time Sys Name
ASMPARAMETERFILE UNPROT COARSE JUN 25 10:00:00 Y REGISTRY.253.722601213

$ asmcmd rm +DATA/asm/asmparameterfile/registry.253.722601213

NOTE: The disk group that holds ASM spfile has to have COMPATIBLE.ASM value of 11.2 or higher.
