"Cannot change immutable field: tier1_lr" error when updating some of the existing Load Balancer virtual services

Products

• VMware Cloud Director

Issue/Introduction

Symptoms:

• Editing and saving a virtual service of an existing Load Balancing section of an Edge Gateway fails with the following error:

Cannot change immutable field: tier1_lr
 

• On /opt/vmware/vcloud-director/logs/vcloud-container-debug.log you have entry similar the one reported below: 

com.vmware.vcloud.common.network.NsxAlbApiException: Cannot change immutable field: tier1_lr at com.vmware.vcloud.fabric.net.nsxalb.NsxAlbRestTemplateErrorHandler.handleError(NsxAlbRestTemplateErrorHandler.java:45)

 

• The error is not seen for new virtual services.

Environment

VMware Cloud Director 10.5.1
VMware Cloud Director for Service Provider 10.x

Cause

This issue occurs due to a change introduced in the 10.5.1 release of Cloud Director.

• The format of tier1_lr has been changed from UUID to /infra/tier-1s/UUID.
• Any pool created before the change will have just the UUID in the tier1_lr field.
• Updating any property in the pool, sets the tier1_lr using the newer format causing it to fail in NSX-ALB. 

Resolution

The issue has been resolved in Cloud Director 10.5.1.1 available at Broadcom Downloads .

Workaround:
If you are unable to upgrade to 10.5.1.1, the only workaround is to recreate the affected entities.

Additional Information

Impact/Risks:
Users are unable to update any existing load balancer pool created before Cloud Director version 10.5.1.
