Additional Information
Note:
- This article is to remove the standalone firewall from Panorama.
- If a HA (High Availability) Firewall Pair must be removed from Panorama, then "config sync" needs to be disabled, and "commit" must be completed prior to starting the removal process.
- If not, due to HA config sync, one of the firewalls may end up with double policies (one from Panorama and the second from config sync of the Peer). This may result in commit failure
Starting from PAN-OS 10.1, there is a new field under Device > Setup > Management > Panorama Settings called Auth Key. If the firewall was managed through Panorama prior to 10.1, this field will likely be blank. As such, the OK button will be greyed out and will not let Panorama IP to be removed. In order to resolve that, give auth key of format "2:<anycharacters>" as shown in snapshot below:
Alternatively, remove Panorama config from CLI. See: PAN-189804
