Troubleshooting the cluster configuration from the CLI

1. If the FortiGates don’t form a cluster, use the following command to re-enter the cluster password. Do this for each cluster unit in case you made an error typing the password when configuring one of the cluster units.

   config system ha

   set password <password>

   end

2. Check that the correct interfaces of each cluster unit are connected. Check the cables and interface LEDs. Use the get hardware nic <interface_name> command to confirm that each interface is connected.

   If the interface is connected, the output should contain a Link: up entry similar to the following:

   get hardware nic port1

   .

   .

   .

   Link: up

   .

   .

   .

3. If the link is down, re-verify the physical connection. Try replacing network cables or switches.
