Failed to run vdcpromo / Firstboot script execution error when installing additional external PSC – which log to look for

Ok. For people who keep getting this when installing additional PSCs:



Unfortunately, the logs that get’s dump in your local PC (where you initiate the installation) doesn’t provide enough information for you to troubleshoot this.

The correct logs to look for would be inside the PSC appliance that gets deployed.

  • SSH to the failed PSC installation
  • Go to the following path:  /var/log/firstboot
  • Look inside:  vmafd-firstboot.py_9000_stderr.log


For this particular instance, we found out that the firewall is blocking some ports which prevents the PSC to join the existing SSO domain.



Hope that helps!
