[INS-30069] Installer has detected that user “oracle” does not belong to the OS group “asmdba” on the following nodes [dc01x02]. These nodes will be ignored and not participate in the configured Grid Infrastructure.


This installation error happened due to lack of proper group for managing the asm operations. You can still ignore this error but to overcome this , do the next step


As the group ASMDBA was missing in node 2, add the group!

[root@dc01x02 oracle]# groupadd asmdba
[root@dc01x02 oracle]# usermod -G asmdba,backupdba,dba,oinstall,racdba,kmdba,dgdba oracle
