Redhat使用7.6以後，驗證的結果與描述有些不相符，重啓後故障會重現，不過卻告知了我異常的原因，給了我解決方向
• 參考二： https://blog.csdn.net/johnyiyang/article/details/103006627
也許是PSU問題，也許是OPatch的原因，總之故障如下，不過卻提供給了我打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] (文檔 ID 2180883.1)
解決方案
隨着PSU、OPatch 和 Redhat的版本提升，雖然單獨一個文檔未能解決該問題，但參考各位大神的方案建議，最終還是攻克了這個難關，如下是我整理的解決方案
- 如下是爲了解決最初遇到的bug：ACFS 導致 root.sh 執行失敗所進行的步驟
CLSRSC-400: A system reboot is required to continue installing.
a. 下載最新OPatch：p6880880補丁 爲了打最新的PSU，所以下載了最新的OPatch
b. 下載最新GI升級補丁：p30920127_122010_Linux-x86-64 此處是爲了修復ACFS的故障
-
執行安裝腳本
./gridSetup.sh -applyPSU /u01/app/30920127 -silent -responseFile /home/grid/grid.rsp -skipPrereqs - 此處是爲了修復ASM啓動失敗的bug
ASM failed to start. Check /u01/app/oracle/cfgtoollogs/asmca/asmca-200419AM113741.log for details.
2020/04/19 11:38:16 CLSRSC-184: Configuration of ASM failed

至此，GRID終於成功默認安裝完成，建議大家還是使用19c吧，對比其它版本，的確要穩定許多，此次是爲了搭建DG所做的操作，所以不得已進行了一次bug的攻克。
