IBM AIX: Data collection for automountd issues

How To


Summary

Debug data collection to troubleshoot automountd issues.


Steps

Follow the steps in the order shown for collecting data.

1. Stop automountd
# stopsrc -s automountd
2. Verify and kill any automountd processes still running
# ps -ef | grep -i auto
# kill -9 <process PID>
3. Save existing automountd ODM entry if any non-default options set
# odmget -q subsysname=automountd SRCsubsys > /<some directory path>/automountd-odmentry.save
4. Get a copy of some files:
# snap -r
# mkdir -p /tmp/ibmsupt/testcase
# cp -rp /etc/auto* /tmp/ibmsupt/testcase/
# cp -p /etc/irs.conf /tmp/ibmsupt/testcase/
# cp -p /etc/rc.nfs /tmp/ibmsupt/testcase/
# cp -p /etc/filesystems /tmp/ibmsupt/testcase/

5. Enable syslog logging
# cp /etc/syslog.conf /etc/syslog.conf.bak
# echo "*.debug /tmp/ibmsupt/testcase/syslog.out rotate size 10m files 4" >> /etc/syslog.conf
# touch /tmp/ibmsupt/testcase/syslog.out
Make the syslogd read the changes to syslog.conf
# refresh -s syslogd
 
6. Change automountd SRC ODM entry to enable automountd debug
# chssys –s automountd –a “-v -d -d -d -d -d” –o /tmp/ibmsupt/testcase/auto.debug –e /tmp/ibmsupt/testcase/auto.debug
The /tmp/ibmsupt/testcase/auto.debug file contains the debug traces from automountd.
7. Start automount
# /usr/sbin/automount
8. Start iptrace
# startsrc -s iptrace -a "-L 300000000 -b /tmp/ibmsupt/testcase/iptrace.bin"
9. Re-create the problem.
10. Stop iptrace
# stopsrc -s iptrace
11. Undo changes to syslog.conf and refresh syslogd
# cp /etc/syslog.conf.bak /etc/syslog.conf
# refresh -s syslogd
12. Collect snap data
# snap -aZc
13. Kill automount processes
# ps -ef | grep -i auto*
# kill -9 <process PID>
14. Restore the default automount entry
# chssys –s automountd –a “” –o /dev/console –e /dev/console
or change back to the saved pre-debug automountd ODM entry at:
/<some directory path>/automountd-odmentry.save
 
15. Start automountd for the changes to take effect
# /usr/sbin/automount
16. Rename snap data
# cd /tmp/ibmsupt
# mv  snap.pax.Z  <case number>.snap.pax.Z 
17. Upload the packaged data or individual files to the IBM secured server using one of upload options provided at:
