When you perform VMFS datastore management operations, vCenter Server uses default storage protection filters. The filters help you to avoid storage corruption by retrieving only the storage devices that can be used for a particular operation. Unsuitable devices are not displayed for selection. You can turn off the filters to view all devices.


Before you change the device filters, consult with the VMware support team. You can turn off the filters only if you have other methods to prevent device corruption.


  1. Browse to the vCenter Server in the vSphere Web Client object navigator.
  2. Click the Manage tab, and click Settings.
  3. Under Settings, click Advanced Settings, and click Edit.
  4. Specify the filter to turn off.
    1. In the Name text box at the bottom of the page, enter an appropriate filter name.

      RDM Filter


      Same Hosts and Transports Filter


      Host Rescan Filter


      If you turn off this filter, your hosts continue to perform a rescan each time you present a new LUN to a host or a cluster.

    2. In the Value text box, enter False for the specified key.
  5. Click Add, and click OK to save your changes.

    You are not required to restart the vCenter Server system.
