does HA/DRS require vcenter to be up

[tdubb123]

if vcenter is down, would HA/DRS still work?

[Troy_Clavell · Accepted solution]

DRS would not work but HA would

[jrmunday]

Agreed with Troy Clavell and also confirmed in Duncan's excellent article;

http://www.yellow-bricks.com/vmware-high-availability-deepdiv/#HA-50basics

So, while HA, by design, will respond to failures without vCenter, HA relies on vCenter to be available to configure or monitor the cluster

[aravinds3107]

HA will work as it just restart the VM's to other host in the cluster, whereas DRS need the analysis the performance of cluster to place the VM's and need vMotion to migrate the VM's so it required vCenter to be available
