FT - Secondary VM Won't Automatically Power On

Hello,

I have a 3 host HA cluster that I'm testing FT on.  When I turn on FT for a particular VM, it enables correctly.  The problem that I'm experiencing is when I actually install a manmade fault.  For instance, if I hard power the host that the primary VM resides, it does not automatically power on the secondary VM on another host.  Any clue on what could be causing this and how I can rectify it?  We are running ESXI 6U2.

Also, am I understanding this correctly....FT is a feature of HA....so in order to turn on FT, I must have an HA cluster with HA enabled.

Thanks for your help in advance!!
