Upgrades from 3.9 to 3.9.1 fails on Configuration Drift fails with error "Failure: A specified parameter was not correct: ConfigSpec.infrastructureTrafficResourceConfig"

Products

• VMware Cloud Foundation

Issue/Introduction

Symptoms:

• Configuration Drift upgrade may fail with error "InvalidArgument: A specified parameter was not correct: ConfigSpec.infrastructureTrafficResourceConfig"
• VI Workload Domains' clusters will not have their virtual Distributed Switch Traffic Resources configured according to the VMware Validated Design recommendations.
• If a VI Workload Domain is on NIOC2, the config drift will fail at 'A specified parameter was not correct: ConfigSpec.infrastructureTrafficResourceConfig'
   

Environment

VMware Cloud Foundation 3.9.x
VMware Cloud Foundation 3.8.x

Cause

This drift is meant to configure VI Workfload Domains in alignment with what is recommended with VVD.

Resolution

Ensure All Workload Domains are upgraded to NIOC3. See https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.networking.doc/GUID-4F40390D-E5F4-4139-AC50-FDB2C4F36B42.html

For deployments content with the current DVS Traffic Resource configurations, leave the current settings as is.

For deployments that would like to align their configurations with VMware Validated Design, please configure with the following:
 

Traffic Type	Shares
Fault Tolerance (FT) Traffic	Low
Management Traffic	Normal
NFS Traffic	Low
Virtual Machine Traffic	High
iSCSI Traffic	Low
vMotion Traffic	Low
vSAN Traffic	High
vSphere Data Protection Backup Traffic	Low
vSphere Replication (VR) Traffic	Low

To Configure from the vCenter Server Web Client:

1. Define Network I/O Control shares for the different traffic types on the the define Workload Domain distributed switch(es).
2. Click the distributed switch for the VI cluster, click the Configure tab, and click Resource Allocation > System traffic.
3. Under System Traffic, configure each of the following traffic types with the following values.

Detailed instructions for assigning these values through the UI can be found here on Page 34 https://docs.vmware.com/en/VMware-Validated-Design/4.3/vmware-validated-design-43-sddc-regiona-deployment.pdf
