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 making any changes to 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.


Launch the vSphere Client and log in to a vCenter Server system.


  1. In the vSphere Client, select Administration > vCenter Server Settings.
