Panorama Device Removal

L7 Applicator

I had to rebuild Panorama 7 on ESX as for some reason after a power outage the image could not be restored...


New installation completed and licensed but I cannot get the firewall 3020 to connect.


I have removed the Panorama settings from firewall and re-applied.


I have added the serial number to Panorama but the firewall is complaining.....


Error:  pan_cmsa_tcp_channel_setup(src_panos/cms_agent.c:623): cms sent untrusted cert!!


I can see the certificate via cli "show panorama-certificate", this shows the certificate from the original Panorama connection but cannot remove it.


So, what do i need to do to rejoin to a new Panorama installation.

give this a try:

> delete authentication user-file ssh-known-hosts user ip <panoramaIP> username panorama

Thanks for your reply...


ssh-known-hosts does not exist yet for panorama

you do that on the firewalls, not on the new panorama


it erases the ssh-known-hosts entry they have for the previous panorama so they can create a new one for the same IP
