Hi
I suggest use https://www.flackbox.com/ to see how to install simulator, they also have youtube video on how to install simulator.
BTW this simulator does not support HA. Please read Simulate ONTAP 9.4 Installation and Setup Guide and check out page 6.
Simulate ONTAP does not support the following features:
High Availability (CFO/SFO)
Fibre channel and SAN connectivity
RLM (Remote LAN Module)
CFE, BIOS, shelf FW, and so on
Multipathing
