You can turn off vSAN for a host cluster.
About this task
When you disable the vSAN cluster, all virtual machines located on the shared vSAN datastore become inaccessible. If you intend to use virtual machine while vSAN is disabled, make sure you migrate virtual machines from vSAN datastore to another datastore before disabling the vSAN cluster.
Verify that the hosts are in maintenance mode.
- Navigate to the host cluster in the vSphere Web Client.
- Click the Configure tab.
- Under vSAN, select General and click Edit to edit vSAN settings.
- Deselect the vSAN Turn On check box.
