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.
