Deleting an organization regional network in VCF Automation 9.x fails with VPC attachment error

Products

• VCF Automation

Issue/Introduction

There are no active deployments for the organization in VCF Automation (VCFA).

When attempting to delete the Regional Networking configuration for the Organization in VCFA, the operation fails. The following error message is observed:

"VPC attachment [/orgs/default/projects/...] delete is not allowed when VPC [path=/orgs/default/projects/...] ip-address allocation consuming connectivity-profile [/orgs/default/projects/...] External ip-block(s)" ... error_code=612946

Environment

VCF Automation 9.0

Cause

The deletion is blocked by stale Virtual Private Cloud (VPC) attachments and active IP address allocations within the NSX Project connectivity profile. NSX Policy prevents the removal of network attachments when orphaned IP allocations or residual VPC resources still exist.

Resolution

To resolve this issue, manually clear the residual resources in NSX before attempting the deletion in VCF Automation:

• Log in to NSX Manager.
• Navigate to the associated Project (e.g., the project identified in the error path).
• Manually delete the residual VPC.
• Access the VCF Automation UI.
• Navigate to the Networking tab of the target Organization.
• Delete the Regional Networking Configuration.
• Proceed with the Organization deletion.
