3PAR VSS Provider for Microsoft Windows 1.6 User’s Guide
The file vsstrace.reg is located under the 3PAR VSS Provider for Microsoft Windows
installation directory. Since VSS logging is volume based, the log file cannot be on the volume
as part of the shadow copy set. The default location for the TraceFile is set to:
c:\vsstrace.txt . Modify it to fit into your system if necessary.
Use Windows Explorer to locate the vsstrace.reg file. Double-click on this file to make it
active.
The trace log will be appended. In order to receive meaningful information, clear out the
contents before a new run begins.
To turn off the VSS tracing, remove the following registry key from the registry database:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Debug\Tracing]
NOTE: You can use the ProvCfg.exe utility with the Log subcommand to
specify the appropriate log level. See Chapter 3, Installation, Upgrade and
Deinstallation -- Using the Command Line Interface to Set Up or Modify an InServ
Connection on page 3.18 for complete details.
