You may know, but there is a Microsoft hotfix rollup that addresses many
known issues with VSS. After testing we made the decision to push them
out to all of our servers.

Thank you,

1. Make sure you have the prerequisite hotfixes installed for Windows
2003
(see the client requirements web page for which hotfixes to install if
you
are not already familar with them). If the hotfixes are not installed,
your
first step should be to install them.

After verifying the hotfixes are installed, see if the problem
continues.
If it does:

2. Try installing and testing the admin command line interface (dsmadmc)
to
see if it can connect to the TSM server. This would help determine
whether
connectivity between TSM client and server is at issue.

Assuming that connectivity is not the issue, then:

3. Start the backup-archive CLI (dsmc.exe). Observe the process in Task
Manager. Do you see it using an CPU? Does memory utilization change? How
about disk I/O (you may need to turn on those columns in the Task
Manager
display, as some of these are not enabled by default).

If there is CPU activity, changes in memory utilization, and/or disk
I/O,
then the client is probably not "hung", but something in the
initialization
routines may be slowing it down. My first though is possibly an issue
with
VSS initialization. In this case, try the following:

4. Run the Windows command "vssadmin list writers". Do you get results
fairly quickly? If that command seems to hang, there this would indicate
a
problem with Microsoft VSS, in which case assistance from MIcrosoft
support
would be the logical next step.

If the vssadmin command works okay, then:

5. Search for article 1412250 (or "vshadow") at the IBM support page
(see
my sig) and follow the steps there to obtain the Microsoft SDK which
includes a useful tool called vshadow.exe. Run vshadow like this:

   vshadow -wm2 > vswm2.out

It will generate a lot of output data. It should run to completion in a
minute or two. If it seems to take forever, then again, this would
appear
to be a problem to take up with Microsoft support.

If none of the above seems problematic thus far, then:

6. Start the client like this from the TSM baclient directory (where
dsmc.exe lives):

   dsmc -traceflags=service -tracefile=tsmtrace.out

and let it sit.

Over time, do you see the trace file growing? If it grows rapidly (say,
to
hundreds of MB), then this might be indicative of some kind of loop.
Kill
the dsmc.exe process, open a PMR, and provide the trace.

The trace file will have *some* amount of data in it. But after, say, an
hour, if you see no additional growth, then use the Microsoft userdump
tool
(see KB article 241215 at support.microsoft.com) to create a dump of the
dsmc.exe process. Kill the process, open a PMR, and provide the trace
and
dump file so we can see where it is stuck.

Andy

The command line is your friend.
