An ADOM has two device modes: Normal (default) and Advanced.
In Normal mode, you cannot assign different FortiGate VDOMs to different ADOMs. The FortiGate unit can only be added to a single ADOM.
In Advanced mode, you can assign a VDOM from a single device to a different ADOM. This allows you to analyze data for individual VDOMs, but will result in more complicated management scenarios. It is recommended only for advanced users.
To change from Advanced mode back to Normal mode, you must ensure no FortiGate VDOMs are assigned to an ADOM.
- Go to System Settings > Advanced > Advanced Settings.
- In the ADOM Mode field, select either Normal or Advanced.
- Select Apply to apply your changes.
