When you are logged in to an ESXi host with the VMware Host Client, you can clear the partition table of a disk device that is accessible from the host.
Before you begin
Verify that the device is not in use by ESXi as boot disk, VMFS datastore, or Virtual SAN.
- Click Storage in the VMware Host Client and click Devices.
- Right-click a device from the list, click Clear partition table and click Yes.
Clearing the partition table might cause data loss.
