IT37310: crtmqm -sx fails with AMQ3812E error if /var/mqm/vols directory does not exist

APAR status

• Closed as program error.

Error description

• When creating the primary queue manager instance in an RDQM
  cluster, the 'crtmqm -sx' procedure creates the queue manager
  directory structure in the /var/mqm/vols folder. This folder is
  created when installing the MQSeriesRDQM package. If the folder
  is missing when attempting to create the primary RDQM Queue
  Manager (crtmqm   -sx QM1), a generic message is displayed in
  the console:
  
   AMQ3812E: Failed to create replicated data queue manager
  configuration.
  

Local fix

• Manually create the missing /var/mqm/vols directory as below and
  retry the crtmqm operation.
  sudo mkdir /var/mqm/vols
  sudo chown mqm:mqm /var/mqm/vols
  sudo chmod 775 /var/mqm/vols
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All IBM MQ RDQM user's who try to create Primary Queue Manager
  and  if there installation missing  /var/mqm/vols Directory.
  
  
  Platforms affected:
  Linux on x86-64
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  MQ is unable to cope up with the missing "/var/mqm/vols"
  directory which causes "crtmqm -sx" to fail with AMQ3812E. Also
  the produced error message is more generic which is not helpful
  to determine the cause.
  

Problem conclusion

• The IBM MQ code has been modified to automatically create
  missing directory /var/mqm/vols and also to improve the
  diagnostics by tracing specific errno and  FDC upon failure.
