SNA IMF Troubleshooting
Problem Resolution
data communications products installed, and any other products you
were using when the problem arose.
• Obtain the version, update, and fix information for all software by
running NMMAINT (for SNA IMF, you also can call the VERS3270
intrinsic). This allows Hewlett-Packard to determine whether the
problem is already known and if the correct software is installed at
your site.
• Record all result messages and numbers that appear at the user
terminal and the system console.
• Run NMDUMP to format the NM log file (NMLG
nnnn .PUB.SYS) that
was active when the problem occurred. You might need to issue the
MPE command SWITCHNMLOG to free the NM log file. For more
information, see the SNA Link/XL Node Manager’s Guide. Inspect
the formatted output and try to locate errors. Prepare the formatted
output and a copy of the log file for your HP representative to
analyze.
• Prepare a listing of the configuration file and the MPE configuration
you are using for your HP representative to analyze. Inspect the
output and try to locate errors.
• Try to determine the general area, within the software, where you
think the problem exists. If you think the problem is caused by an
SNA link, refer to the SNA Link/XL Node Manager’s Guide and
follow the guidelines there for gathering information for problems.
• Document your interim, or “workaround,” solution. The cause of the
problem can sometimes be found by comparing the circumstances in
which it occurs with the circumstances in which it does not occur.
• Save copies of any SNA trace and communications link trace files
that were active when the problem occurred, for your HP
representative to analyze.
• If the problem involves NMMGR, give a copy of NMMGRF.PUB.SYS to
your HP representative.
• If a system failure occurs, a full memory dump must be taken.
• If a fatal SDLC link error has occurred, a message in this format is
displayed on the operator’s console:
SDLC ( LinkName ) Error ErrorNum :
SDLC ( LinkName ) Info: Status= Status ,
Loc= LocationId , Path= PhysPath
Be sure to include this error message in the SR exactly as it appears
on the operator’s console.
• Save copies of all active or in-use trace files for analysis by your
HP representative.
