Network adapters disappear from a recently provisioned VM in vRA UI after data collection

Products

• VMware Aria Suite

Issue/Introduction

Symptoms:

• Virtual machine (VM) provisioning is successful from vRealize Automation and appropriate network adapters are connected for those VMs.
  
  
• Network adapters disappear from recently provisioned machines in vRA UI after data collection is performed on compute resources.
  
  
• In the vSphere Agent log file, you see empty network names for all machines after data collection:

<obj type="Network">
<attr name="Name" value />
<attr name="MacAddress" value="00:50:56:8d:f9:7c" />
<attr name="portID" value="428" />
</obj>

Environment

VMware vRealize Automation 7.3.x
VMware vRealize Automation 7.0.x
VMware vRealize Automation 7.1.x
VMware vRealize Automation 6.2.x
VMware vRealize Automation 7.2.x

Cause

This issue occurs due to mismatch between the dvPortGroup key and Moid, a condition which is not supported by vRA. As a result, when vRA runs data collection, it cannot determine which networks the machines are attached to and updates the networking information in the UI to reflect that.

 

The mismatch between the dvPortGroup key and Moid is commonly caused by DVS export import operations between two different vCenters. This issue won't occur if you create a new DVSwitch instead of exporting and importing the old one.

Resolution

 

To resolve this issue, build a new distributed switch on the vCenter Server and migrate all the hosts to it.

 

Note: Before making changes to your vCenter Server configuration, Broadcom recommends taking appropriate steps to back up your databases and snapshot the environment to provide a thorough fall-back point.
