I'm looking in the web console or directly on the edge device the command to use the on-demand failover for the edge device ... Didn't find anyhting i'm on NSX 6.2.4 ... Any direction will be appreciated!
There's currently no option to do the Edge failover through the CLI or GUI. There's an API call you can do to initiate the failover. Here's a great example: NSX 6.2.3 and Triggered Edge Failover ~ CCIE5851
