I faced with that error message during 19C RAC installation during running runcluvy.sh

/runcluvfy.sh stage -pre crsinst -n rac1,rac2  -orainv oinstall  -osdba dba -verbose

Error :

PRVE-10077 : NOZEROCONF parameter was not specified or was not set to ‘yes’ in file “/etc/sysconfig/network” on node

Check for zeroconf check failed

Pre-check for cluster services setup was unsuccessful on all the nodes.

Actually error indicates also answer.

Solution:

After adding “NOZEROCONF=yes” into “/etc/sysconfig/network” on both servers, then rerun it again successfully without errors any more.

PS: Its better to restart network interface to eliminate possible errors.
