IJ32668: COMMANDS LIKE "MMCES STATE CLUSTER NFS" ALWAYS SHOW PARSEABLE OUTPUT, EVEN WITHOUT -Y

APAR status

• Closed as program error.

Error description

• mmces state
  
  There's no more difference in format of stdout
  when running e.g. "mmces state cluster NFS"
  or "mmces state cluster NFS -Y".
  With former versions we used to
  have a nice table list when not using -Y.
  But, today, we get e.g. this:
  
  [root@nas22ces01-i ~]# mmces state cluster NFS
  mmcesstatecluster::HEADER:version:reserved:
  reserved:NODE:COMPONENT:STATE:EVENTS:
  mmcesstatecluster::0:1::::nas22ces01-i:NFS:HEALTHY:
  csm_resync_forced,no_longwaiters_found,
  ccr_quorum_nodes_ok,service_running,node_resumed,

  Work around:
  None
  
  Problem trigger:
  Parsing of the machine readablle
  output was not done correctly
  
  Platforms affected:
  ALL Linux OS environments (CES nodes)
