For versions 6.x, 7.x, 8.x and 9.x, when the VMware integration fails the vddk log files could reveal more information on the root case.
To enable TRIVIA debugs you must update the vepa_vddk.config file. This file is under /etc/opt/omni/client or C:\ProgramData\OmniBack\Config\client on the Vepa backup host.
1. Edit the file with log level 6.
2. Restart the Data Protector INET in the Backup host
The transport logs are interlaced with the executed commands in the VEPALIB_VMWARE_EXECUTION_THREAD file.
