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

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
