You might need to remove a virtual flash resource deployed on local flash devices to free the devices for other services.
You cannot remove a virtual flash resource if it is configured with host swap cache or if the host has virtual machines configured with Flash Read Cache that are powered on.
- In the vSphere Web Client, navigate to the host that has virtual flash configured.
- Click the Manage tab and click Settings.
- 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.
