Edge node replacement failing with error "Update/Replace of transport node is not allowed"

Products

• VMware NSX

Issue/Introduction

Edge node replacement in the Edge Cluster fails with error message "Update/Replace of transport node is not allowed, as change of failure domain from old xxxx to new xxxx is violating placement of active-standby in different domains."

Environment

VMware NSX

VMware NSX-T Data Center

Cause

• The new edge deployed is part of a system-default-failure-domain while the existing node that needs to be replaced is part of a different user-defined failure domain.
• Existing failure domains can be validated with below API call:
  GET /api/v1/failure-domains
• The failure domain of the edge can be validated with below API call:
  GET /api/v1/transport-nodes/<tn-id>

Resolution

The new edge node should be a part of the same failure domain which the existing edge node is a part of.
Change the failure domain of the new edge node using the below API call: 

PUT /api/v1/transport-nodes/<transport-node-id>
