Rename Diskgroup having OCR , Vote File , ASM SPILE [ID 1335975.1] 适用于11R2； 11R2提供renamedg，可在磁盘组dismount时将其重命名；如果该磁盘组包含OCR/vote file，则dismount前需将其迁移至中间磁盘； 大致思路如下： 创建一个临时磁盘组temp，将OCR/vote file迁移至此； 将spfile也迁移到temp，重启CRS； 卸载并重命名原磁盘组，并重新加载； 将ocr/vote file/spfile迁回，重启CRS； 创建临时磁盘组 create diskgroup TEMP normal redundancy disk 'ORCL:DISK4' ,'ORCL:DISK5' ,'ORCL:DATA4' ,'ORCL:DATA6' attribute 'compatible.rdbms'='11.2.0.0', 'compatible.asm'='11.2.0.0', 'au_size'='4M'; 迁移ocr/vote file $ORACLE_HOME/bin/bin/ocrconfig -add +TEMP $ORACLE_HOME/bin/bin/ocrconfig -delete +DATA $ORACLE_HOME/bin/crsctl replace votedisk +TEMP 完成后调用ocrcheck检查完整性 迁移spfile 重启CRS crsctl stop crs crsctl start crs 重命名磁盘组 alter diskgroup data dismount; renamedgphase=both dgname=DATA newdgname=CRS verbose=true 输出如下 Parsing parameters..
