AIX client activity trace

z/OS Network File System Guide and Reference
SC23-6883-00

The AIX IP trace contains a trace of the IP activity from the AIX client:
rm /tmp/ibmsupt 
Note: Make sure that there is enough space under /tmp for the IP-traces.

Systems with high TCP/IP activity may use up to 20 MB per minute.

snap -gkitn (takes 2-3 minutes and collects all necessary AIX diagnostic information).

  • To start the AIX IP trace, issue the following AIX command:
    startsrc -s iptrace -a "-s -d -b 
    /tmp/ibmsupt/testcase/iptrc.bin" 
    
    cd /tmp/ibmsupt/testcase 
    script cmd_log (puts all keybaord actions to file cmd_log in current directory)
    Ping -c 5 (z/OS NFS server)  showmount -e 
    cd to NFS mounted z/OS filessysem  
    cp /etc/filesystems /tmp/ibmsupt/testcase/filesystems.out 
    mount
  • Reproduce the problem in a system with minimal activity.
  • To stop the AIX IP Trace, issue the following AIX command:
    stopsrc -s iptrace  
  • To format the Trace Report, issue the following AIX command:
    ipreport -rns /tmp/ibmsupt/testcase/iptrc.bin > /tmp/ibmsupt/testcase/iptrc.out  
    Note: The formatted version of the trace will be approximately five times as large as the binary version.
  • To stop script recording, issue the following console command:
    CTRL-D 
  • To generate snap.pax.Z file in /tmp/ibmsupt directory, issue the following console command:
    snap -c  
  • Send snap.pax.Z file to NFS service personnel.
