You might need to remove a virtual flash resource deployed on local flash devices to free the devices for other services.
Verify that the virtual flash resource is not configured with host swap cache.
Verify that no virtual machines configured with Flash Read Cache are powered on the host.
- In the vSphere Web Client, navigate to the host that has virtual flash configured.
- Click the Configure tab.
- Under Virtual Flash, select Virtual Flash Resource Management and click Remove All.
After you remove the virtual flash resource and erase the flash device, the device is available for other operations.
