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
4.查看资源的状态[root@rac2 ~]# crs_stat.shName Target State Host------------------------------ ---------- --------- -------oggvip ONLINE ONLINE rac1ora.CRS.dg ONLINE ONLINE rac1ora.DATA.dg ONLINE ONLINE rac1ora.FRA.dg ONLINE ONLINE rac1ora.LISTENER.lsnr ONLINE ONLINE rac1ora.LISTENER_SCAN1.lsnr ONLINE ONLINE rac1ora.OGG.dg ONLINE ONLINE rac1ora.asm ONLINE ONLINE rac1ora.cvu ONLINE ONLINE rac1ora.gsd OFFLINE OFFLINEora.net1.network ONLINE ONLINE rac1ora.oc4j ONLINE ONLINE rac1ora.ons ONLINE ONLINE rac1ora.rac.db ONLINE ONLINE rac1ora.rac1.ASM1.asm ONLINE ONLINE rac1ora.rac1.LISTENER_RAC1.lsnr ONLINE ONLINE rac1ora.rac1.gsd OFFLINE OFFLINEora.rac1.ons ONLINE ONLINE rac1ora.rac1.vip ONLINE ONLINE rac1ora.rac2.ASM2.asm ONLINE ONLINE rac2ora.rac2.LISTENER_RAC2.lsnr ONLINE ONLINE rac2ora.rac2.gsd OFFLINE OFFLINEora.rac2.ons ONLINE ONLINE rac2ora.rac2.vip ONLINE ONLINE rac2ora.registry.acfs ONLINE ONLINE rac1ora.scan1.vip ONLINE ONLINE rac1
这里如果磁盘没有挂载需要手动挂载1.以sysasm身份登陆asm实例,查看磁盘组SYS@+ASM1> select name,state from v$asm_diskgroup;
2.如果没有挂载alter diskgroup ***** mout;验证OCR[root@rac1 oracle]# ocrcheckStatus of Oracle Cluster Registry is as follows :Version : 3Total space (kbytes) : 262120Used space (kbytes) : 3396Available space (kbytes) : 258724ID : 2129345179Device/File Name : +CRSDevice/File integrity check succeeded
