Issue/Introduction

This article outlines the Day2 operational guidance to support Cross vCenter NSX (Universal objects) use cases on VMware Cloud Foundation versions 2.3.2 and above. 

Note: Depending on the desired target version, there may be intermediate steps required to ensure a smooth and effective upgrade process. All these steps are documented in this KB. Ensure you review the relevant section in detail.

Note: This KB article only applies to the Ready Nodes based VMware Cloud Foundation. For Integrated Systems refer to the respective OEM vendor for guidance.

Environment

VMware Cloud Foundation 2.3.x

Resolution

Note: VMware Cloud Foundation SDDC Manager does not automate the deployment and configuration of NSX universal logical constructs for cross site/regional networking use cases.  However, you may request Cross vCenter NSX support on Cloud Foundation SDDC as an RPQ from your VMware account team.

VMware Cloud Foundation minimum requirements: 

1. Dual sites VMware Cloud Foundation 2.3.2+ Enterprise deployment configured per the VMware Cloud Foundation Site Protection Recovery VMware Validated Design guidance. 
2. Single Site VMware Cloud Foundation 2.3.2+ Enterprise (VMware Cloud Foundation Management Workload Domain - configured as Primary and Tenant Workload Domain as Secondary using NSX universal objects)

Perform these operational steps to maintain a stable operational environment during VMware Cloud Foundation LCM "NSX components" upgrades-patches etc. 
 

Scenario 1

Workload Domains not enabled for Cross vCenter NSX:

• Initiate the NSX Upgrade on any Workload Domain that do not have Cross Site NSX configured.

 

Scenario 2

For any Workload Domain with Cross-Site NSX configured:

1.  From VMware Cloud Foundation SDDC Manager UI, start the LCM upgrade on the Primary NSX site first.  The upgrade is expected to fail with an error similar to:

 Description {"details' The secondary  NSX Managere 10.24.64.40 [version:6.26.4977495] has different version with the Primary NSX Manager [version:  6.3.4]. Cannot upgrade the controller. ","errorCode"126009,"moduleName"."core-services"}

2.  Start the SDDC Manager LCM Update on the VMware Cloud Foundation Secondary NSX Site next.  The upgrade is expected to fail with the an error similar to:

​Description {"details' Controller needs to be upgraded before upgrading the Network Fabric","errorCode"128006,"moduleName"."core-services"}

3. Restart the upgrade on the VMware Cloud Foundation Primary NSX Site instance, this time it will complete successfully.
4. Restart the upgrade on the VMware Cloud Foundation Secondary NSX Site instance this time, it will complete successfully.
