有点晕倒了ORA-15018: diskgroup cannot be created ORA-15307: disk DATAA_0001 not discov？

disk DATA_0001 not discoverable by CSS
看日志

Oracle的安装问题，需要看日志，虽然日志不一定能准确的定位问题，但是总比你发的这些前端显示报错能强一点点

11.2.0.1确实是存在很多BUG，最终版的11.2.0.4都EOS了，11.2.0.1完全不建议初装使用。

至于这个问题是不是由bug引起的，根据你提供的信息还判断不出来

你确定是按照官方Guide操作的么?install log 中的详细报错是什么？
1、首先你的磁盘权限不需要给到777，660即可。
2、你的磁盘权限所属组是否正确？请给出你RAC中的用户规划：为何不按照官方指导设置为grid:asmadmin 3、reserve_policy属性否已经更改？
忠告一点：如果不是应用强制要求，新安装Oracle数据库不建议安装11.2.0.1版本，推荐11.2.0.4，且最好打上最新PSU。
