在11.2或者12.1的RAC中,ocr和votedisk可以放到asm中,而很多人安装系统把ocr和votedisk放到一个单独的asm 磁盘组里面,但是如果这个磁盘组坏了,而数据所在的磁盘组是好的,这个时候该怎么恢复呢？这里的恢复分两种情况，一种是有ocr备份的恢复,另外一种是无ocr备份的恢复。但是在一般情况下ocr是每4个小时自动备份一份，因此大部分的系统中都会有ocr的备份。本blog主要对于Oracle 12c rac在有ocr备份，存储ocr,votedisk的asm磁盘组异常恢复
确定ocr,votedisk,asm spfile存在一个独立asm diskgroup中

至此在ocr 磁盘组异常,而有ocr备份的情况下故障恢复完毕，对于没有ocr备份的故障，只能通过重建ocr来完成，，大概步骤为
--deconfigure(root)
remote node
# <$GRID_HOME>/crs/install/rootcrs.pl -deconfig -force -verbose
lastnode
# <$GRID_HOME>/crs/install/rootcrs.pl -deconfig -force -verbose -lastnode
--配置信息重建ocr等(grid)
# $GRID_HOME/crs/config/config.sh
