Issue/Introduction

• NSX upgrade interface fails to load
• Upgrade coordinator logs shows a stale entry

var/log/upgrade-coordinator/upgrade-coordinator.log
[Timestamp]  INFO http-nio-127.0.0.1-7442-exec-4 NsxBaseRestController 3596582 SYSTEM [nsx@6876 audit="true" comp="nsx-manager" level="INFO" subcomp="upgrade-coordinator"] UserName:'admin' ModuleName:'upgrade-coordinator' Operation:'GET@/api/v1/upgrade/status-summary' Operation status: 'failure' Error: [Edge UCP] Issue retrieving Edge transport nodes [UUID, ] aggregate information from MP.

• Edge referenced in the log error has already been removed from the environment
• From within NSX User Interface, searching using Edge UUID may return some objects such as segments, T1s, T0s, Edge Cluster etc

Environment

VMware NSX
VMware NSX-T Data Center

Resolution

Note: Before proceeding you must confirm the objects are not in use.

From the NSX User Interface delete the objects that reference the previously removed edge. This may differ based on specific configuration within the environment.

1. Example order that unused configuration can be deleted.

1. Segment
2. T1
3. Static route (T0)
4. BGP neighbours (T0)
5. Uplink Interfaces (T0)
6. T0
7. Edge Cluster (Cluster may contain other edges. These will have to be removed from cluster before the cluster can be deleted)

2. Identify which Manager is the Orchestrator Node.

nsx-manager> get service install-upgrade
<date>
Service name:      install-upgrade
Service state:     running
Enabled on:        <NSX Manager Orchestrator IP>

3. SSH to the NSX Manager where the Orchestrator is running and restart the Upgrade Service. 

nsx-manager>restart service Install-upgrade
