Issue/Introduction

When trying to deploy NSX Advanced Load balancer, after selecting the version the NEXT button is greyed out and we get the following error - 

"Something went wrong. Please retry or contact the service provider and provide the reference token."

Environment

VCF 5.x

Cause

When SDDC Manager checks the compatibility for the Advanced Load Balancer bundle we see the following in the logs - 

domainmanager.log:

As a result of the above the bundle gets marked as "bundletoignore" in lcm.log and the NEXT button shows greyed out

Resolution

The Upgrade Compatibility checks can be disabled using the steps below to allow the Deploy to continue - take a snapshot of the SDDC Manager as a precaution when editing configuration files

To disable the upgrade compatibility checks, follow the steps below:

  1. SSH into SDDC Manager appliance with the vcf user and su to root.
  2. Check the status of the flag in file: /opt/vmware/vcf/lcm/lcm-app/conf/compatibility.flag
  3. If value is true update the property vcf.compatibility.controllers.compatibilityCheckEnabled to false
  4. Save and close the file.
  5. Restart Lifecycle Management by running the command: systemctl restart lcm

Note: Re-enable the compatibility checks once the upgrades are complete to ensure guardrails are in place with respect to Bill-of-Materials compatibility for future upgrades

Additional Information

To re-enable the compatibility checks, follow the steps below:

  1. SSH into SDDC Manager appliance with the vcf user and su to root.
  2. Edit the file: /opt/vmware/vcf/lcm/lcm-app/conf/compatibility.flag
  3. Update the property vcf.compatibility.controllers.compatibilityCheckEnabled to true
  4. Save and close the file.
  5. Restart Lifecycle Management by running the command: systemctl restart lcm
