Error description

  • The MODIFY ZFS,FSINFO command documentation is incorrect.
    
    Issuing F ZFS,FSINFO,MY.FSNAME.*,EXCEPTION fails with an
    IOEZ00844E
    
    Despite the documentation indicating that BASIC is the default
    level of output, the user MUST specify a level of output for the
    command to work
    
    Ex.
    F ZFS,FSINFO,MY.FSNAME.*,BASIC,EXCEPTION
    
    
    ANALYSIS:
    zFS trace will show the command failure.
    
    KNOWN IMPACT:
    Command fails with
    IOEZ00844E Invalid option EXCEPTIONS.
    IOEZ00024E zFS kernel: MODIFY command -
    FSINFO,OMVS.PRV.*,EXCEPTIONS 656
    failed.
    
    VERIFICATION STEPS:
    IOEZ00844E Invalid option EXCEPTIONS.
    IOEZ00024E zFS kernel: MODIFY command -
    FSINFO,OMVS.PRV.*,EXCEPTIONS 656
    failed.
    
    ADDITIONAL SYMPTOMS:
    IOEZ00844E Invalid option EXCEPTIONS.
    IOEZ00024E zFS kernel: MODIFY command -
    FSINFO,OMVS.PRV.*,EXCEPTIONS 656
    failed.
    

Local fix

  • BYPASS/CIRCUMVENTION:
    Specify the output level with the command
    Ex.
    F ZFS,FSINFO,MY.FSNAME.*,BASIC,EXCEPTION

    This apar is being used to clarify the MODIFY ZFS FSINO
    command. The fsinfo parameter  options are positional which
    caused the reported failure.
    

Problem conclusion

  • This documentation APAR is providing information for the
    MODIFY ZFS FSINFO command in the z/OS File System
    Administration publication (SC23-6887-XX) for z/OS 2.5 and
    z/OS 3.1.
    
    In Chapter 10. z/OS system commands, some of the parameter
    sections for the modify fsinfo command are being updated.
    
    The fsinfo parameter section is being updated as follows:
    
    fsinfo
    Displays detailed information about a zFS file system, which is
    also known as a zFS aggregate. All fsinfo options are
    positional.
    
    The aggrname parameter section is being updated as follows:
    
    aggrname
    Specifies the name of the aggregate that the detailed zFS
    information is for. The aggregate name is not case-sensitive and
    is converted to uppercase. To specify multiple aggregates with
    similar names, use an asterisk (*) at the beginning, at the end,
    or both at the beginning and the end of aggrname as a wildcard.
    
     - If aggrname is specified with wildcards but no other options
       are specified, the default information display is basic.
    
     - If a single aggregate name is specified as aggrname but no
       other options are specified, the default information display
       is full.
    
     - If there are other options that are specified after aggrname,
       you must specify one of the basic, full, owner, or reset
       options.
    
    For more information, see "Usage notes for displaying file
     system information" on page 110
    and "Examples of displaying file system information" on page
    112.
    
    The all parameter section is being updated as follows:
    
    all
    Displays information for all aggregates in the sysplex. This
    uses the default information display option of basic if no
    other options are specified.
    
    The basic parameter section is being updated as follows:
    
    basic
    Displays a line of basic file system information for each
    specified file system. This option is the default in the
    following situations:
    
     - The all option is specified but no other options are
       specified.
     - aggrname is specified with wildcards but no other options
       are specified.
    For more information about what is displayed when the basic
    option is used, see Table 15 on page 200.
    
    The exceptions parameter section is being updated as follows:
    
    exceptions
    Displays information about any specified aggregate that is
    quiesced, disabled, had grow failures, is low on space, failed
    to convert a directory to version5, contains at least one
    V4 directory, disk size that exceeded the space monitoring
    threshold, or is damaged. Any specified aggregate is also
    displayed if it has had XCF communication failures or an error
    because it ran out of space or when doing I/O.
    
    This option cannot be specified with reset, select, and aggrname
    with no wildcard. An information display option must be
    specified.
    
    The reset parameter section is being updated as follows:
    
    reset
    Resets zFS statistics that relate to each specified file system.
    reset cannot be specified with basic, full, owner, exceptions,
    select, or sort. reset must be specified with aggrname or all
    option.
    
    The select=criteria  parameter section is being updated as
    follows:
    
    select=criteria
    Displays each specified file system that matches the criteria.
    
    This option cannot be specified with exceptions, reset, and
    aggrname with no wildcard. An information display option must
    be specified.
    
    To use this option, specify a selection criteria from Table 14
    on page 199. Multiple criteria are separated by spaces.
    
    The sort=sort_option parameter section is being updated as
    follows:
    
    sort=sort_option
    Sorts the displayed information using the value of sort_option.
    The default is to sort by Name.
    An information display option must be specified.
    
    This option cannot be specified with reset. For a list of the
    sorting options, see Table 17 on page 203.
    
    In the "Usage notes for displaying file system information", the
    following sentence is being added to the list of methods to
    specify aggregates, based on their names list :
    
     - all can be specified to mean all file systems that are
       currently mounted in the sysplex.
    
    The following line is being added to the supported syntax
    examples:
    
    F ZFS,FSINFO,aggrname*,BASIC,EXCEPTIONS
