We are trying to install and configure two node Oracle Grid infrastructure 12.1.0.2 for one of our customer, but there was an issue with on of the cluster node and installation cannot proceed further. All pre-reqs checks were successful, we tested ssh it was working fine. Even nodes communication was working without any issues from both the nodes. Error Screen Shot: Its a very generic error that points to invalid hostname, but honestly hostname was defined correctly. After lot of troubleshooting we found solution, there was problem with "hostname -i", when we see the hostname IP address it was pointing to IP Address + MAC address which is not correct. After fixing this issue installation completed with any issues. Hope it helps, thanks for reading.  regards, Zaheer
