You can power off a vSAN cluster to perform maintenance or upgrades.


If the vCenter Server VM is running on the vSAN cluster, migrate the VM to the first host, or record the host where it is currently running.


  1. Power off all virtual machines that are running on the vSAN cluster.
    If the vCenter Server is running on the vSAN cluster, the vCenter Server VM must be powered off last.
  2. Place all ESXi hosts that compose the cluster in maintenance mode.
  3. Power off the ESXi hosts.
