ASM下遷移spfile

How to move ASM spfile to a different disk group [ID 1082943.1]
適用於11R2
有兩種方法：採用create pfile/spflie透過中間檔案遷移；適用asmcmd自帶的spcopy命令；
第一種方法比較簡單，步驟如下
create pfile='/tmp/pfile+ASM.ora' from spfile;
create spfile='+PLAY' from pfile='/tmp/pfile+ASM.ora';
crsctl stop has
crsctl start has --重啟驗證

下面介紹一下spcopy命令
由於GPnP profile記錄有spfile路徑資訊，因此需新增-u選項自動更新

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.
