VMware vSAN Stuff

Shutting Down and Restarting the vSAN Cluster

When necessary, you can shut down the entire vSAN cluster.

If you plan to shut down the vSAN cluster, you do not need to manually disable vSAN on the cluster.


If vCenter Server is hosted in the vSAN cluster, do not power off the vCenter Server VM.

Click the Monitor tab, and select vSAN > Resyncing Components.

The vSphere Client becomes unavailable.

Connect to the host and use the host client or esxcli command to place the host into maintenance mode with no data migration (no action).

On the physical box where ESXi is installed, press the power button until the power-on sequence begins.

The ESXi host starts, locates its VMs, and functions normally.

After you power on the hosts, the vSAN cluster is automatically recreated.

You can ignore any misconfiguration status message if you did not make network configuration changes and the vSAN cluster was working as expected before you shut down the cluster. The message disappears after at least three hosts join the cluster.
