The NSX upgrade tab never finishes loading and displays a spinning circle indefinitely.

Products

• VMware NSX

Issue/Introduction

• Unable to perform any tasks from System -> Upgrade in NSX UI, the page fails to load and displays only a spinning circle indefinitely.
• NSX Manager node running the UC was re-deployed mid-upgrade due to an environmental issue (For example, vSAN failure).
• A different NSX Manager node is running the UC service now after a stable NSX Manager Cluster has been formed again.
• You see log entries similar to the following in the NSX manager log /var/log/upgrade-coordinator/upgrade-coordinator.log:

ERROR http-nio-127.0.0.1-7442-exec-1 MPUpgradePlanServiceImpl 8082 SYSTEM [nsx@6876 comp="nsx-manager" errorCode="MP30427" level="ERROR" subcomp="upgrade-coordinator"] [MP UCP] Invalid Upgrade method SERIAL for MP UPgrade

• Please note there is another KB article which identifies an issue that presents with same symptom: The NSX upgrade tab never finishes loading but the cause and resolution is different and can only be ascertained from findings in the upgrade-coordinator.log file.

Environment

VMware NSX-T Data Center
VMware NSX

Cause

The issue can occur when an NSX Manager node running the Upgrade Coordinator service is lost to any environmental issue mid-upgrade ( i.e. when UC along with some other components of the NSX environment like Edges/Hosts have been upgraded but MP upgrade is not yet complete)

Resolution

Workaround

To workaround this issue, issue the following command from the NSX manager CLI (while logged in as root):

curl -ku 'admin' -X POST 'https://localhost/api/v1/upgrade/plan?action=reset&component_type=MP'

 

Please note that the above command needs to be run on all Manager nodes in the Cluster.

Additional Information

The Manager node running the UC service can be identified by running the following command on any Manager node admin CLI:

get service install-upgrade
