Chapter 9 High Availability for FortiOS 5.0 : Virtual clusters : Example: virtual clustering with two VDOMs and VDOM partitioning : General configuration steps
  
General configuration steps
The section includes web‑based manager and CLI procedures. These procedures assume that the FortiGate‑620B units are running the same FortiOS firmware build and are set to the factory default configuration.
General configuration steps
1. Configure the FortiGate units for HA operation.
Optionally change each unit’s host name.
Configure HA.
2. Connect the cluster to the network.
3. Configure VDOM settings for the cluster:
Enable multiple VDOMs.
Add the Eng_vdm VDOM.
Add port5 and port6 to the Eng_vdom.
4. Configure VDOM partitioning.
5. Confirm that the cluster units are operating as a virtual cluster and add basic configuration settings to the cluster.
View cluster status from the web‑based manager or CLI.
Add a password for the admin administrative account.
Change the IP addresses and netmasks of the port1, port2, port5, and port6 interfaces.
Add a default routes to each VDOM.
