Hello,
I am trying to install Oracle Grid Infrastructure 12c Release 2 and hit the following error when it is trying to check the User Equivalence.

Rac nodes are as following
rac1.support.lab
rac2.support.lab
In the gridSetupActions2017-04-02_06-46-39PM.log, I can see the following error which is not informative at all.
INFO: [Apr 2, 2017 7:37:02 PM] Preparing to check passwordless SSH Connectivity between nodes: [rac1, rac2]

I am able to login to individual nodes as oracle user and ran the following commands which tell me that the ssh has been configured correctly.
[oracle@rac1 ~]$ ssh rac1 date
Sun Apr 2 19:41:06 EDT 2017
[oracle@rac1 ~]$ ssh rac2 date
Sun Apr 2 19:41:09 EDT 2017
[oracle@rac2 ~]$ ssh rac1 date
Sun Apr 2 19:41:25 EDT 2017
[oracle@rac2 ~]$ ssh rac2 date
Sun Apr 2 19:41:27 EDT 2017
I have checked the hostnames specified in the cat /etc/hosts and they are in lower case.
cat /etc/hosts
[oracle@rac1 ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.X.X.X rac1.support.lab rac1
172.X.X.X rac2.support.lab rac2
I am able to ping both the machines from each of the nodes as oracle user.
SSH and SCP commands are in the following directories.
[oracle@rac1 ~]$ which ssh
/usr/local/bin/ssh
[oracle@rac1 ~]$ which scp
/usr/local/bin/scp
I have edited the cvu_config and added the following and that did not help too.
# To override SSH location
ORACLE_SRVM_REMOTESHELL=/usr/local/bin/ssh
# To override SCP location
ORACLE_SRVM_REMOTECOPY=/usr/local/bin/scp
Any help here is greatly appreciated.
Thanks
