The port needs to be open on the agent host. Check if a firewall is running on the agent host:
# service iptables status If the firewall is running, you either need to open port 8145 on it or turn it off. Run the following command to turn off the port: # service iptables stop To test if the connectivity has been restored, go to the Inventory page in the SnapCenter GUI and select 'Refresh Resources'
I had same issue with v3.0 as well. Followed the steps in the threads and others, did not help. I finally download the Linux plugin and installed it at the Linux manually, after that, went to SnapCenter GUI, went through add host steps without any problem. Just FYI
