To generate VDDK logs
1 Open the vmware.cfg file in any text editor. You can find this file in <NetVault Backup home>\config on Windows and <NetVault Backup home>/config on Linux.
2 Set the value for the following entry to “True”:
[Custom:GenerateVddkLogsOnDisk]
Value = True
By default, this value is set to False, and must be left so unless requested by Technical Support.
3 Retry the operation with the new setting. This will generate VDDK log files entitled vixDiskLib*.log in the following directories:
• Windows – <SYSTEMDRIVE>\WINDOWS\Temp\vmware-SYSTEM or "C:\Users\<username>\AppData\Local\Temp\2\vmware-<username>"
• Linux – /tmp/vmware-root
4 After capturing the logs, reset [Custom:GenerateVddkLogsOnDisk] to False.
