/u01/grid/crs/crs/install/rootcrs.pl -deconfig -force  删除集群配置信息
rm –rf /etc/oracle/*
rm -rf /etc/init.d/init.cssd
rm -rf /etc/init.d/init.crs
rm -rf /etc/init.d/init.crsd
rm -rf /etc/init.d/init.evmd
rm -rf /etc/rc2.d/K96init.crs
rm -rf /etc/rc2.d/S96init.crs
rm -rf /etc/rc3.d/K96init.crs
rm -rf /etc/rc3.d/S96init.crs
rm -rf /etc/rc5.d/K96init.crs
rm -rf /etc/rc5.d/S96init.crs
rm -rf /etc/oracle/scls_scr
rm -rf /etc/inittab.crs
rm -rf /var/tmp/.oracle/*
cd /etc/oracle
ls
rm -rf ocr.*
rm -rf /tmp/CVU*
rm -rf /var/opt/oracle
rm -rf /usr/local/bin/dbhome
rm -rf /usr/local/bin/oraenv
rm -rf /usr/local/bin/coraenv
rm -rf /u01/
3.删除所有asm磁盘，清除所有的asm磁盘头信息：
/etc/init.d/oracleasm deletedisk OCR_VOT1  
... ...
dd if=/dev/zero of=/dev/sda1 bs=1024k count=1
4. 重启服务器
如果是集群套件安装失败，执行后三步。
