Windows Smart Server build / rebuild fails at ConfigureOperatingSystem step with error like -
Running: /bin/mkdir -p /mnt/onapp-tmp-mez8srhj5aoi3v/Drivers Fatal: SCP did not finish successfully ()
All OnApp versions with Smart Server option
Error can occur because of missing drivers files for that Windows version. Files can be found on the repo here.
Example file: http://templates.repo.onapp.com/Windows/drivers/smart_server_windows_2012r2_x64.tgz
Then download the file to /data on the CP to fix the error.
