You can turn off vSAN for a host cluster.

When you turn off vSAN for a cluster, all virtual machines and data services located on the vSAN datastore become inaccessible. If you have consumed storage on the vSAN cluster using vSAN Direct, then the vSAN Direct monitoring services, such as health checks, space reporting, and performance monitoring, are not available. If you intend to use virtual machines while vSAN is off, make sure you migrate virtual machines from vSAN datastore to another datastore before turning off the vSAN cluster.

Prerequisites

Verify that the hosts are in maintenance mode. For more information, see Place a Member of vSAN Cluster in Maintenance Mode.

Procedure

  1. Navigate to the vSAN cluster.
  2. Click the Configure tab.
  3. Under vSAN, select Services.
  4. Click Turn Off vSAN.
  5. On the Turn Off vSAN dialog, confirm your selection.
