IJ45805: mmprotocoltrace fails with "/tmp/mmfs: No such file or directory"

APAR status

• Closed as program error.

Error description

• The command to start smb traces "mmprotocoltrace start smb -c
  <ip address> " failed with
  an error message "/tmp/mmfs: No such file or directory".
  The corresponding log file /var/adm/ras/mmprotocoltrace.log
  shows error messages of this failing command, but not any reason
  detail.
  

Local fix

• Manually check if all CES nodes have the data collection path
  available.
  This is /tmp/mmfs by default, or the path given with the "-l
  LogFileDir" option in the mmprotocoltrace command.
  

Problem summary

  Benefits of the solution:
  The code prints out the node where the isssue occured. This will
  help debugging the reason better.
  
  Work Around:
  Manually check if all CES nodes have the data collection path
  available.
  This is /tmp/mmfs by default, or the path given with the "-l
  LogFileDir" option in the mmprotocoltrace command.
  
  Problem trigger:
  The mmprotocoltrace command tries to access all CES nodes to
  collect data from them.
  Each of these nodes must have the given data collection
  directory available and the correct rights for the
  mmprotocoltrace user (like root or sudo user) to access it.
