解决：

第一种原因可能是DNS没有配置，从11.2.0.2开始DNS是必须配置的。

配置DNS

卸载CRS，清理裸设备，使用asmlib方式绑定磁盘

loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]').  Hitting <ENTER> without typing an
answer will keep that current value.  Ctrl-C will abort.

然后重新安装Grid Infrastructure。

(2)我的原因是：

重装了好几次，都是报这个错误，后来发现虚拟机的磁盘紊乱了，本来第一块二磁盘变成了第四块，但是两个虚拟机的顺序是一致的，后来把磁盘删除了又重新加上后搞定了。

a 在设置中删除并创建磁盘（vmware可以在线增删磁盘）

b 操作系统删除分区，并新建分区

c 重新绑定裸设备

d 重新安装Grid Infrastructure
