Objective 1.1 - vCenter Storage Filters

From the ESX Configuration Guide.

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

Before making any changes to the LUN filters, consult with the VMware support team. You can turn off the filters only if you have other methods to prevent LUN corruption.


  1. In the vSphere Client, select Administration > vCenter Server Settings.
  2. In the settings list, select Advanced Settings.
  3. In the Key text box, type a key.
              1. Key                                                                     Filter Name
                config.vpxd.filter.vmfsFilter                                    VMFS Filter
                config.vpxd.filter.rdmFilter                                     RDM Filter
                config.vpxd.filter.SameHostAndTransportsFilter       Same Host and Transports Filter
                config.vpxd.filter.hostRescanFilter                           Host Rescan Filter
  4. NOTE If you turn off the Host Rescan Filter, your hosts continue to perform
    a rescan each time you present a new LUN to a host or a cluster.

  5. In the Value text box, type False for the specified key.
  6. Click Add.
  7. Click OK.

You are not required to restart the vCenter Server system.
