With HA having both the heartbeat network and the datastore is a host isolation response (keep powered on/shutdown/power off) triggered if only the mgmt network goes down or does both the datstores (used for hb) and the network have to go down before an isolation response it triggered?
Thank you for your post.
but I am still a little confused to what exactly happens with the vm itself.
In an isolated vs partioned host.

So if the datastore is up but network is down and the isolation response is configured to shutdown vm. Will the VM remain on original host or will it be restarted by the master onto a new host. What about if the VM is configured to stay powered on?
The answer to that is: Only the "network heartbeat" is used for the "Isolation Response". So if management network is isolated the isolation response is triggered.
Hi hurdle
Welcome to communities .
Isolated
- Is not receiving heartbeats from the master
- Is not receiving any election traffic
- Cannot ping the isolation address [usually the default gateway
Partitioned
- Is not receiving heartbeats from the master
- *Is* receiving election traffic (emphasis mine)
- (at some point a new master will be elected at which the state will be reported to vCenter).
