1.所有节点停止集群
crsctl stop crs
如果停止不了可以使用
crsctl stop crs -f
2.每个节点执行/crs/install/rootcrs.pl,来撤销集群配置
[root@rac1 oracle]# /u01/app/grid/11.2.0/crs/install/rootcrs.pl -deconfig -verbose -force
[root@rac2 oracle]# /u01/app/grid/11.2.0/crs/install/rootcrs.pl -deconfig -verbose -force
3.每个节点的root用户执行grid安装目录下的root.sh脚本（一次执行）
[root@rac1 oracle]# /u01/app/grid/11.2.0/root.sh
[root@rac2 ~]# /u01/app/grid/11.2.0/root.sh
