Challenge

Management Pack fails to build the environmental topology. The vmspi.log (default location: C:\Program Files\Veeam\Veeam Virtualization Extensions for System Center\Collector\Log) contains the following entries:
 

+** System.NullReferenceException: Object reference not set to an instance of an object. at nworksCore.TopologyNode.Clone()

Cause

Some host hardware objects may fail to return mandatory properties, such as NIC MAC address or NIC name. In this case Veeam Colelctor would fail to process such objects.
 

Solution

The hotfix prevents Veeam Collector from crashing and provides additional output about the object with missing properties. Download the hotfix here.

Follow these steps to apply the fix.

  1. Stop Veeam VMware Collector service.
  2. Make a backup of VeeamCollector.Core.dll (default path: C:\Program Files\Veeam\Veeam Virtualization Extensions for System Center\Collector).
  3. Unpack the downloaded .zip and replace VeeamCollector.Core.dll with the file from the archive.
  4. Start Veeam VMware Collector service.
