After the invalid record is removed, runcluvfy checks and continues to install everything normally through. OUI.
It is because of invalid records in/etc/hosts that the RAC Installation check fails. remind you to install the RAC file carefully.

• Install ORACLE 12C single-node RAC
• View cpu/memory/swap/network/disk information using common AIX commands
• 10g rac Installation notes
• When localhost. localdomain is missing in hosts, the listener startup time is too long.
• A single Nic is bound with multiple IP addresses, leading to errors such as TNS-12542
• IP = FIRST
• Use PXE to brush XD
• Analysis of database connection latency caused by domain name resolution
