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.
