Now before you say "What an idiot!" let me say that I would totally agree with you!!
I created a shutdown workflow to shutdown my lab and forgot to exclude the orchestrator engine that I am using (it's an embedded orchestrator inside of a VRA). So the workflow got to the VRA appliance and did the task to shut it down. This of course stopped the workflow as the appliance shutdown. Now when I start up the appliance it resumes the workflow and of course the first thing it does is shuts down the appliance. Did I tell you I know that I'm an idiot?
Is there a way to start VRA but tell it to cancel any outstanding workflows?
