Error description

  • When defining a range of LUs using the define_lu_0_to_3_range
    command and specifying name_attributes = USE_HEX_IN_NAME a valid
    and correct but unexpected configuration is produced: any name
    that would have an alpha character (A-F) in the suffix is split
    into an individual LU definition, and any name that would have
    only numberic characters (0-9) in the suffix is split into
    ranges (00-09, 10-19, 20-29, etc.). This does not cause
    problems, but it does increase the size and complexity of the
    configuration file, and for large configurations can
    significantly increase the time necessary to load when starting
    the node.
    

Local fix

  • Stop the sna software (sna stop).
    Edit the sna_node.cfg file to manually code the
    define_lu_0_to_3_range definition.
    Start the sna software (sna start).

      PROBLEM DESCRIPTION:
      When defining a range of LUs using the
      define_lu_0_to_3_range command and specifying
      name_attributes = USE_HEX_IN_NAME a valid and correct but
      unexpected configuration is produced: any name that would
      have an alpha character (A-F) in the suffix is split into
      an individual LU definition, and any name that would have
      only numberic characters (0-9) in the suffix is split into
      ranges (00-09, 10-19, 20-29, etc.). This does not cause
      problems, but it does increase the size and complexity of
      the configuration file, and for large configurations can
      significantly increase the time necessary to load when
      starting the node.
    
      PROBLEM SUMMARY:
      When an LU 0-3 pool of LUs is defined using hex extensions
      the configuration file does not store this as a single
      record. Instead it is broken up into multiple
      define_lu_0_to_3 records so making the file more difficult
      to maintain. Furthermore when the LUs are queried they are
      sorted in order of the EBCDIC name where the fact that
      alphabetics are lexically lower than digits means that the
      LUs are not displayed in order of LU address.
    

Problem conclusion

  • The code has been altered to keep the configuration
    records together. In addition the sorting has been
    changed to use ASCII names so that the LUs are now
    in order of LU address.
    

Temporary fix
