The messages in machine-readable format can be converted into human-readable format by  the newly created tool  ltfsee_catcsvlog , which is run by the following command:  /opt/ibm/ltfsee/bin/ltfsee_catcsvlog /var/log/ltfsee_trc.log The  ltfsee_catcsvlog  command accepts multiple log files as command-line arguments. If no  argument is specified,  ltfsee_catcsvlog  reads from  stdin . This section describes ways to solve persistent IBM Spectrum Archive EE problems. If an unexpected and persistent condition occurs in the IBM Spectrum Archive EE  environment, contact your IBM service representative. Provide the following information to  help IBM re-create and solve the problem: The operating system automatically generates system log files after initial configuration of the  IBM Spectrum Archive EE. Provide the results of the  ltfsee_log_collection  command to  your IBM service representative. IBM Spectrum Scale writes operational messages and error data to the IBM Spectrum Scale  log file. The IBM Spectrum Scale log can be found in the  /var/adm/ras  directory on each  node. The IBM Spectrum Scale log file is named  mmfs.log. date . nodeName , where  date  is the  time stamp when the instance of IBM Spectrum Scale started on the node and  nodeName  is  the name of the node. The latest IBM Spectrum Scale log file can be found by using the  symbolic file name  /var/adm/ras/mmfs.log.latest . The IBM Spectrum Scale log from the prior start of IBM Spectrum Scale can be found by  using the symbolic file name  /var/adm/ras/mmfs.log.previous . All other files have a time  stamp and node name that is appended to the file name. At IBM Spectrum Scale start, files that were not accessed during the last 10 days are deleted.  If you want to save old files, copy them elsewhere. Example 10-19 shows normal operational messages that appear in the IBM Spectrum Scale  log file.
