I spin up a new VM ESXi appliance for our new secondary Panorama server. After loading the config from our primary server the following errors below are shown. Please note that I did not input yet the serial number on this server. Maybe it is the cause of the problem?
Software Version: 10.1.5 - h2
Appreciate your help and response on this matter.
Thank you for the post @EarvinYu
when it comes to secondary Panorama, the only concept that is supported is Panorama HA where 2 units are acting as either of the roles: primary-active / secondary-passive. If you built a standalone Panorama as your secondary appliance, the limitation you are going to face is a managed Firewall can be registered only to a single Panorama set at a time.
Regarding the error you posted, it looks like you configured post policy security/nat rules with target Firewalls and Firewalls Serial Numbers are not in the configuration as registered Firewalls. Could you please confirm how you exported / import configuration? Based on my experience running configuration export includes everything including all Serial Numbers and there is no manual intervention needed to add Serial Numbers manually.
Just in case, could you navigate to: Panorama > Setup > Operations > Export named Panorama configuration snapshot, then select: running-config.xml. Do not check: "Select Device Group & Templates". In this way full configuration will be exported. Edit the configuration file to change Panorama management interface IP address to new Panorama (Otherwise you will have IP address duplication) and change the name to avoid confusion. Login to other Panorama you built and navigate to Panorama > Setup > Operations > Import > Import named Panorama configuration snapshot, then Load configuration by going to: Panorama > Setup > Operations > Load > select file to load, then select only this option: "Retain rule UUID", then perform commit. After performing this step all configuration will be on one to one bases with your original Panorama.
As closing note, even though I do not know exactly how you ended up in the state that configuration is imported with missing Firewall Serial Numbers, I believe that adding Serial Numbers manually fill fix the issue. Alternatively, changing your post policy security/nat rules to remove limit to push policies only to target devices should resolve the issue as well.
