Improved design for onboarding FortiGate HA clusters to prevent auto-link failure

Improved design for onboarding FortiGate HA Clusters to prevent auto-link failure.

To add a FortiGate HA cluster using model devices in FortiManager:

1. If using ADOMs, ensure that you are in the correct ADOM.
2. Go to Device Manager > Device & Groups.
3. Click Add Device.
4. Select Add Model HA Cluster. The Add Device wizard opens.
   
5. Populate the mandatory fields including the Name, HA Mode, Cluster ID, Cluster Name, and Password.
   
6. Enter the FortiGate device's Serial Number.
7. Optionally, click Add HA Secondary to add and configure a secondary cluster device.
   
8. Configure the remaining settings as needed, and click Next.
9. After the wizard is finished, FortiManager adds the FortiGate HA cluster in Device Manager > Device Groups.
   
   
10. On FortiGate, go to Security Fabric > Fabric Connectors > FortiManager, and configure the fabric connector using the FortiManager IP for each FortiGate device.
    
    After the FortiManager IP is added to all FortiGate devices, model device auto-linking to real devices begins. The following tasks are performed while auto-linking model devices to real devices:
    
    After auto-link is complete, the HA cluster in Device Manager > Device & Groups displays additional information about the HA cluster, including the HA Status and Config Status.
