Issue/Introduction

Symptoms:
  • When attempting to converge a 6.x PSC and vCenter the process fails almost immediately with no entries logged into the converge.log.
  • On the GUI you see "example.vmware.com cannot be converged".
  • In the converge_rest.log in /var/log/vmware/converge you see entries similar to:
2019-05-01 21:29:32,528 - vcenter.system_config_impl - INFO - feature ConvergeAPI is enabled.

Environment

VMware vCenter Server Appliance 6.5.x

Cause

The "converge_running_flag" file in /var/log/vmware/converge is present which causes the convergence tool to believe that a convergence is in progress.

Resolution

To resolve the issue:
  • Log into the VCSA with SSH.
  • Navigate to /var/log/vmware/converge.
  • Move the "converge_running_flag" file back one directory:
mv  converge_running_flag ../
  • Remove the file /root/velma/task.json if exists
rm /root/velma/task.json
  • Perform the convergence operation again.
Note: Reboot the VCSA and retry the convergence if you observe same error after performing above steps.

Additional Information

Impact/Risks:
As per part of the convergence process a backup should always be taken.
