1 Pod Host Offline, All VMs Shut Down

[Asai]

Greetings,

I have 2 hosts in a pod, and 3 primary storage shares. I just ran into 
an issue where a cable accidentally got damaged which took host 2 
offline and primary storage 2 offline, but ALL of my VMs shut down 
spontaneously.  Weird, because only half of my VMs are running on host 2 
and primary storage 2.  Even the VMs on host 1 and primary storage 1 
shut down.  Can anyone shed light on why this would have happened and 
how I can avoid this in the future?

Much thanks,
Asai
