VMware Discovery Limitations

  • DFM can discover the total number of licenses and available licenses for each feature, but only when the user has Global.Licenses permission. If the user does not have such permissions, these attributes of the License Feature CI are not populated.

  • Different versions of ESX Servers (versions 3.0 and 3.5) report the feature_is_edition flag differently for the esxFull feature: for the older version it is reported as false and for the newer version it is reported as true. Because of this discrepancy, DFM does not report this attribute.

  • Different versions of ESX Servers (versions 3.0 and 3.5) report the total or available license counts differently for ESX-specific features (nas, iscsi, vsmp, san) that are included in the esxFull edition license. For these features, DFM does not report these attributes.

  • There is a difference between the VMware protocol versions: certain attributes appear only in newer versions and do not appear in previous versions. As a result, when using an old protocol certain attributes are not discovered, especially for clusters and licenses.

  • DFM does not discover or report licensing information for vCenter\ESX server version 4.0 or above.

  • DFM does not report information about the order of teamed interfaces. You can group server physical interfaces of an ESX server into NIC Teaming groups, while specifying the order of such interfaces in a group (first, second, and so on). Information about what interface are teamed is reported but the order of these interfaces is not.
