Redhat使用7.6以后，验证的结果与描述有些不相符，重启后故障会重现，不过却告知了我异常的原因，给了我解决方向
• 参考二： https://blog.csdn.net/johnyiyang/article/details/103006627
也许是PSU问题，也许是OPatch的原因，总之故障如下，不过却提供给了我打PSU的方向
• Installation Grid Infrastructure 12c Release 2 – root.sh, CLSRSC-184, CLSRSC-258 (Doc ID 2289380.1)
• The root.sh Fails with ORA-29783:GPnP Attribute SET Failed With Error [CLSGPNP_NOT_FOUND] (文档 ID 2180883.1)
解决方案
随着PSU、OPatch 和 Redhat的版本提升，虽然单独一个文档未能解决该问题，但参考各位大神的方案建议，最终还是攻克了这个难关，如下是我整理的解决方案
- 如下是为了解决最初遇到的bug：ACFS 导致 root.sh 执行失败所进行的步骤
CLSRSC-400: A system reboot is required to continue installing.
a. 下载最新OPatch：p6880880补丁 为了打最新的PSU，所以下载了最新的OPatch
b. 下载最新GI升级补丁：p30920127_122010_Linux-x86-64 此处是为了修复ACFS的故障

执行安装脚本
./gridSetup.sh -applyPSU /u01/app/30920127 -silent -responseFile /home/grid/grid.rsp -skipPrereqs - 此处是为了修复ASM启动失败的bug

至此，GRID终于成功默认安装完成，建议大家还是使用19c吧，对比其它版本，的确要稳定许多，此次是为了搭建DG所做的操作，所以不得已进行了一次bug的攻克。
