创建一个asm Disk Group Name 组，并给一个名称ORC，并选择下面的三块盘，然后 Next
错误的原因是由于磁盘数和冗余层级不匹配：
如果创建用来存放OCR和VOTEDISK的ASM磁盘组，那么External、Normal、High三种冗余级别对应的Failgroup个数是1、3、5。也就是说，创建这三种冗余级别的磁盘组至少分别需要1、3、5个ASM磁盘。
如果创建用于非OCR和VOTEDISK存储的ASM磁盘组，那么External、Normal、High三种冗余级别对应的Failgroup至少是1、2、3。也就是说，创建这三种冗余级别的磁盘组至少分别需要1、2、3个ASM磁盘。
*给这个组，设置一个密码
这里选择不使用用IPMI
指定不同的ASM组，这里默认
这里安装向导会帮你填写集群软件的安装路径，我们继续next，这里我们需要注意的是oracle_Home不能是oracle_base的子目录
选择grid安装清单目录
环境检测出现resolv.conf错误，是因为没有配置DNS，可以忽略
Install 继续安装
安装grid完成，提示需要root用户依次执行脚本orainstRoot.sh ，root.sh （一定要先在rac1执行完脚本后，才能在其他节点执行）

回到图形化安装界面
这个报错不用去管，不影响使用，点击ok ，在next
点击yes
安装完成
到这里oracle RAC 就部署完成！！！
验证，基于oracle RAC的特性，查看IP地址，会发现 hosts文件里面的与节点对应的IP都有，VIP和scan IP会启动成功后自动出现在网卡上
