Certain functionalities, such as vSAN or virtual flash resource, require that you use clean devices. You can erase an HHD or flash device and remove all existing data.


  • Make sure that the host is in the connected state.

  • Verify that the devices you plan to erase are not in use.

  • Required privilege: Host.Config.Storage


  1. Navigate to the host.
  2. Click the Configure tab.
  3. Under Storage, click Storage Devices.
  4. Select one or more devices and click All Actions > Erase Partitions.

    If you are erasing a single device, a dialog box with partition information opens.

  5. For a single device, verify that the partition information you are erasing is not critical.
  6. Click OK to confirm your change.
