You can turn off vSAN for a host cluster.
When you disable the vSAN cluster, all virtual machines and data services located on the vSAN datastore become inaccessible. If you have consumed storage on the vSAN cluster using the vSAN-Direct, then the vSAN Direct monitoring services, such as health checks, space reporting, and performance monitoring, are also disabled. 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 vSAN cluster.
- Click the Configure tab.
- Under vSAN, select Services.
- Click Turn Off vSAN.
- On the Turn Off vSAN dialog, confirm your selection.
