Reverting to Multi VDOM mode

If your FortiGate-6000 or 7000 is operating in Split-Task VDOM mode, you can use the information in this section to revert back to Multi VDOM mode.

You can revert to Multi VDOM mode by resetting your FortiGate-6000 or 7000 to factory default settings by entering the execute factoryreset command. You will loose all configuration settings by entering this command, including network settings. However, the FortiGate-6000 or 7000 will be in Multi VDOM mode.

You can revert to Multi VDOM mode from the CLI or the GUI. The CLI process is recommended because it involves fewer steps.

Reverting to Multi VDOM mode from the CLI (recommended)

The following steps show how to use the CLI to switch from Split-Task VDOM mode to Multi VDOM mode.

1. If required, use the following command to set the Security Fabric role to root by unsetting the upstream IP address:

   config global

   config system csf

   unset upstream-ip

   end

2. If the Security Fabric group name is blank, use the following command to add a group name:

   config global

   config system csf

   set group-name <name>

   end

   The group name may be blank if the FortiGate-6000 or 7000 had joined a Security Fabric.

3. Enter the following command to switch to Multi VDOM mode:

   config global

   config system global

   set vdom-mode multi-vdom

   end

   You are logged out of the CLI.

4. Log into the GUI or CLI.

   The FortiGate-6000 or 7000 will be operating in Multi VDOM mode. The FG-traffic VDOM will still be available. However, it will be empty and you can choose to delete if you do not need it.

Reverting to Multi VDOM mode from the GUI

The following steps show how to use the GUI to switch from Split-Task VDOM mode to Multi VDOM mode.

2. Disable FortiGate Telemetry, go to Security Fabric > Settings and disable FortiGate Telemetry and select Apply.

3. Go to System > Settings > System Operation Settings and select Multi VDOM and select OK.

   You are logged out of the GUI.

4. Log into the GUI.

   The FortiGate-6000 or 7000 will be operating in Multi VDOM mode. The FG-traffic VDOM will still be available. However, it will be empty and you can choose to delete if you do not need it.

   Also, Security Fabric will not be enabled and the Security Fabric > Settings > FortiGate Telemetry GUI page will be hidden.

   set status enable

   unset upstream-ip
