注意这个提示,我们需要将默认生成的命令根据提示在不同节点以root用户身份登录去执行。
The deconfig command below can be executed in parallel on all the remote nodes. Execute the command on the local node after the execution completes on all the remote nodes.
Run the following command as the root user or the administrator on node "rac02".

在这里我需要告诉大家的是卸载grid完成之后,默认的grid和oracle的密码无效了,需要重新修改,cvuqdisk包也被自动卸载了需要重新安装。接下来重新执行root..sh脚本就不会报错了。
