You must gather traces for Data Protection for Microsoft Exchange,
the Tivoli® Storage
Manager application
programming interface (API), and the DSMAGENT processes to ensure
a good diagnosis of the Volume Shadow Copy Service (VSS) operation.
The following traces are the different traces to gather
when you diagnose Data Protection for Exchange VSS operational problems:
- Data Protection for Exchange trace
- To create the trace flag, issue the "/TRACEFILE" and "/TRACEFLAGS" command-line
options with the following example command:
TDPEXCC BACKUP SG1 FULL /TRACEFILE=DPTRACE.TXT /TRACEFLAG=SERVICE
Enable tracing for FlashCopy® Manager.
See the IBM® Tivoli Storage FlashCopy Manager Installation
and User's Guide for information about how to enable tracing.
- Tivoli Storage
Manager API
trace
- Enable tracing with the DP/Exchange dsm.opt file
and the "TRACEFILE" and "TRACEFLAGS" keywords.
The following text is an example of the entry in the DP/Exchange dsm.opt file:
TRACEFILE APITRACE.TXT
TRACEFLAG SERVICE
- DSMAGENT trace
- Enable tracing with the dsmagent (baclient) dsm.opt file
and the "TRACEFILE" and "TRACEFLAGS" keywords.
The following text is an example of the entry in the dsmagent
(baclient) dsm.opt file:
TRACEFILE AGTTRACE.TXT
TRACEFLAG SERVICE PID TID ENTER ALL_VSS SBRM RESTORE
The
trace flag, in this instance, is ALL_VSS (you might need different
traceflags, depending on the circumstance).
- Exchange VSS Writer tracing
- Event logging is the only extra tracing that can be turned on.
Complete these steps to modify the level of event logging for the
Exchange Store Writer:
- Open the Exchange Management Console.
- Find the server object.
- Right-click the server on which you want to increase the logging
level and click Properties or Manage
Diagnostic Logging Properties, depending on the Exchange
version.
- Click the Diagnostics Logging tab.
- Expand the MSExchangeIS node in the Services pane
and click System.
- Click Exchange writer in the Categories pane
and select the logging level.
- Click Apply and then OK to
close the Properties dialog box.
- Enable the Volume ShadowCopy service debug trace features in Windows
