Gathering information
To gather information to report a problem, complete the following steps:
1.
Write a complete description of the problem. Describe the events leading up to and including
the problem. Attempt to describe the source and symptoms of the problem.
Include in your description: HP-UX commands used; communication subsystem commands
used; job streams; result codes and messages; and data that can reproduce the problem. Also
provide a network map with the host name, IP (Internet address), and station address of
each system connected to the HP system.
Illustrate as clearly as possible the context of any message(s). Prepare copies of information
displayed at the system console and user terminal.
2.
Obtain the version, update, and fix information for all software. To check the HP APA
version number, enter the following command:
# what /stand/vmunix | grep -i -e hp_apa -e pagp -e lacp
To check the version of your kernel, enter
uname -r
.
This information enables HP to determine if the problem is already known and if the correct
software is installed at your site.
3.
Prepare copies of the following files:
•
/etc/rc.config.d/netconf
•
/etc/rc.config.d/hp_apaconf
•
/etc/rc.config.d/hp_apaportconf
•
/etc/lanmon/lanconfig.ascii
4.
Enter the
nwmgr -v [-c lanx | -S driver-name]
command and record messages
about the status of the NIC.
5.
Enter the
nwmgr
command and record the output.
6.
Enter the
nwmgr --st -c lanx
command and record the output.
7.
Record all error messages and numbers that appear at the user terminal and the system
console.
8.
Save all network log files. Make sure that
Error
and
Disaster
log classes are enabled
when log files are collected.
Prepare the formatted output and a copy of the log file for your HP representative to further
analyze.
9.
Prepare a listing of the HP-UX I/O configuration you are using for your HP representative
to further analyze. Use the
ioscan
command to help collect this information.
10. Prepare a list of your switch trunking configuration related to this problem.
11. Try to determine the general area within the software where you think the problem exists.
See the appropriate reference manual and follow the guidelines on gathering information
for that product.
12. Document your interim or workaround solution. You can typically find the cause of the
problem by comparing the circumstances in which it occurs with the circumstances in which
it does not occur.
13. Create copies of any Internet or HP APA link trace files that were active when the problem
occurred for your HP representative to further analyze.
14. In the event of a system failure, a full memory dump must be taken. Use the HP-UX
savecore
utility to save a core dump. Send the output to your HP representative.
