Symptom


VM-Series firewall was rebooted, and post reboot, the Serial number shows as “Unknown” in Dashboard and in CLI “show system info”
 
  • Collect the CPUID and UUID from PA-VM instance either via WebUI > Dashboard or using below CLI command:
> show system info
family: vm
model: PA-VM
serial: unknown
vm-mac-base: 7C:89:C1:27:8C:00
vm-mac-count: 256
vm-uuid: 247D7900-0A84-4E58-9EEF-58D2D48416F2
vm-cpuid: KVM:54060500FFFB8B0F
vm-license: VM-700 vm-mode: KVM
cloud-mode: non-cloud
sw-version: 9.0.4

Environment


  • Platform: PA-VM
  • PAN-OS / Plugin Version: Any
  • Deployment: Existing


Cause


  • Serial number associated with CPUID and UUID on license server does not match with CPUID and UUID of PA-VM instance
  • PA-VM was moved to different host which causes the underlying CPUID and/or UUID to change. However, these changes would not take affect in PAN-OS until reboot.

 


Resolution


  • Engage Support Team to edit the CPUID and UUID on backend server to match with the PA-VM instance and then retrieve license on PA-VM. This will cause the PA-VM to reboot automatically.
