Pre-check for cluster services setup was unsuccessful.
Checks did not pass for the following node(s):
rac01

$
I understand the error is ignorable but why create an ignorable error in the first place?
Next, I would like to look at the bottom line to know if the check passed for failed and if the failure is false positive, then it would require wasted time for investigation.
A better alternative is to exclude eth0 from the check using -networks eth1,eth2 to have successful setup.
Pre-check for cluster services setup was successful.
