HA - Datastore PDL/Host Isolation response

Hi,

Is there any reason why you would not set the action to "Power off and restart VMs" when there is an PDL?

On the other hand I understand that with APD the issue might be temporary so leaving it to Disabled.

With regards to Host Isolation and in a vSAN cluster, heartbeats go via the same vSAN vmkernel, does this mean that an isolated host has lost access to the vSAN datastore?

Thanks
