Environment

• VMware Lifecycle Manager
• VMware NSX

Cause

The vLCM service is likely in inconsistent state due to an activity that has occurred on the vCenter in the past, e.g. VM snapshot or vMotion, and requires a restart. 

Resolution

To fix this issue, please follow the steps below:

1. SSH to the vCenter, and switch the console to shell.
2. Restart the vLCM/VUM service:
   vmon-cli -r updatemgr
3. Repeat the upgrade workflow.
