在安装RAC时，有时候我们可能会安装失败，需要重新安装GI/CRS，如果卸载不干净，重装过程中还可能会失败，下面简单列出了删除GI/CRS的步骤，适应于11g,12c的环境

   1.删除集群配置

      /pgold/orgrid/oracle/product/121/crs/install/rootcrs.pl -deconfig  -verbose -force

      /pgold/orgrid/oracle/product/121/crs/install/rootcrs.pl -deconfig  -verbose -force -lastnode 注意：最后一个节点要加上-lastnode

   2.删除OS上相关配置文件及ORACLE软件

       find /etc /tmp /var/tmp/ -ls|egrep 'ohas|oratab|oraInst|crs|CVU|^oracle|^Ora|.oracle' |egrep -v 'release|asm'   查看确认要删除的文件，如果没问题，执行下面的命令

       find /etc /tmp /var/tmp/ -ls|egrep 'ohas|oratab|oraInst|crs|CVU|^oracle|^Ora|.oracle' |egrep -v 'release|asm' |awk '{print $11}' |xargs rm -rf

   3.清除之前磁盘组的头部

       dd if=/dev/zero of=/dev/<device name> bs=1M count=100


删除集群配置
