VMKernel adapter validation failure "is not assigned to a dedicated port group" during installer stage.

Products

• VMware SDDC Manager / VCF Installer

Issue/Introduction

When attempting to deploy VCF 9.1.0.0, the host validation stage fails. The following error is shown in the VCF Installer Validation page:

Host #### VMKernel adapter #### is not assigned to a dedicated port group. Ensure Host #### VMKernel adapter #### is assigned to a dedicated port group.

Environment

VMware Cloud Foundation 9.1x

Cause

When a VDS is imported as part of the deploy, the moids typically change while the keys remain the same. This mismatch causes the hostVmkTrafficTypeValidator to fail because it cannot find the expected port group reference.

Resolution

A permanent fix for this issue is under development for a future release.

Note: Before skipping this validation, manually ensure that only one vNIC is assigned to each traffic type and that a dedicated port group is used for every traffic type on each host.

To unblock the installer and proceed with deployment, run the following: 

1. Use SSH to log in to the VCF installer appliance with su then elevate to root
2. Then run the following commands
   cd /etc/vmware/vcf/operationsmanager
vi application.properties
3. Add the following property to the file: skip.assessment.external.validation.hostVmkTrafficTypeValidator=true
   Save the file and restart the operations manager service (systemctl restart operationsmanager) for the changes to take effect.
