You can power off a vSAN cluster.
Before you begin
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.
- Power off all virtual machines that are running on the vSAN cluster.
The vCenter Server virtual machine must be powered off last.
- Place all ESXi hosts that compose the cluster in maintenance mode.
Run the esxcli command to set the vSAN mode for entering the maintenance state.
esxcli system maintenanceMode set -e true -m noAction
- Power off the ESXi hosts.
