If vCenter goes down – what will work and what doesn’t ?


Things that continue to work if vCenter is down:

  • Fault Tolerance will continue to work for the configured VMs. However, in case of a failover, no new secondary VMs will be created.
  • HA will continue to work
  • You can take snapshot of the VM by connecting to the ESXi host using vSphere client
  • VMs will continue to work
  • dvSwitch will continue to work
  • vSwitch will continue to work

What will not work?

  • vMotion will not work since vMotion requires vCenter server
  • Storage vMotion will not work
  • DRS will not work since DRS requires vMotion.
  • You cannot deploy VMs from templates
  • You cannot clone a VM
