• The NSX manager may have been restored from backup after the upgrade-coordinator was upgraded or the upgrade-plan is not cleaned up after an incorrect upgrade attempt.

Environment

VMware NSX

Cause

A failed upgrade event can leave the upgrade-plan traces and if another upgrade is attempted with a different version, the validation will fail and upgrade-coordinator will fail to load the Upgrade page

Resolution

This issue is resolved in VMware NSX 4.2.0, available at Broadcom downloads.

If you are having difficulty finding and downloading software, review KB Download Broadcom products and software.

Workaround:

Delete the stale upgrade plan

• From root shell of all the managers, run "service upgrade-coordinator stop".
  
  
• Delete the Upgrade Plan by invoking below API on one of the manager
  
  curl -ik -u admin -H "X-Allow-Overwrite: true" -H "Content-Type: application/json" -X DELETE https://<mp-ip>/api/v1/upgrade-mgmt/plan

• From root shell of all the nodes, run "service upgrade-coordinator start".
  
  
• Proceed with MUB upload and UC upgrade.
