Troubleshooting Tip: Command 'diagnose hardware deviceinfo psu' not working on Fortigates after FortiOS 7.6.3

The following command fails when run on the FortiGate:

FortiGate-200G # diagnose hardware deviceinfo psu

command parse error before 'psu'
Command fail. Return code -61

In the example above , the command fails as the FortiGate 200G does not have removable power-supplies, but instead only contain multiple AC inputs to the internal power-supply. This approach is used on other SOC3/SOC4/SP5 platforms that contain dual-inputs. The above command was previously available prior to FortiOS 7.6.3 due to a firmware bug and it's removal is intentional and expected for devices that do not have removable power supply units. 

For devices that contain dual power inputs but not removable PSU's , use  'execute sensor list' instead to display PSU status.

FortiGate-200G # execute sensor list
[HW monitor sensors]
1 PSU [1] ....................... OK
2 PSU [2] ....................... LOST
