Hi !
I have some questions related to new ha functions in vsphere 5
as I found, there is a master ha in the cluster which monitors other hosts and protected vms through two type of heartbeats (network and datastore) and move vms if necessary. if that host fails, an election is held and new ha master is determined by vcenter server.
ok ! what happens if we install vCenter Server as a virtual machine inside the hosts which is the master ha in a cluster. if this host fails (something like a power out) its agent is also going away and also the vcenter is destroyed. So, who is gonna hold the election and introduce the new ha while the old ha and vCenter are out of play.
I know that ha agents are not fully dependent on vCenter and runs if the host holding vcenter is away (vms including vcenter or moved to another host are restarted on another one) but i think this one is different because of new master role
my next question is about different kinds of events which can happen to slave hosts and making them partitioned or isolated. I will ask them later (after this question is answered Image may be NSFW.
Clik here to view.
thanks to you all
