List - Just thought I would share this information should you want to move from v4 to v5 zFS files. This is for z/OS V2.1. You would need to check for your level of z/OS.
There is a parm you can use to set the default format of a zFS filesystem to V5 in IOEFSPRM. format_aggrversion=4 Sets the default format for new zfs datasets to v4 format_aggrversion=5 Sets the default format for new zFS datasets to v5 I am afraid there is no mass conversion utility, but there is something you might find useful and that is the change_aggrversion_on_mount IOEFSPRM option. With this option enabled zFS v4 datasets would be converted to v5 then next time they are mounted. This can also be done with the converttov5 configuration option in IOEPRMxx or with CONVERTTOV5 on the mount command itself. To maximize the conversion I would enable both change_aggrversion_on_mount and CONVERTTOV5. See this manual on z/OS Moutn command: https://ibm.biz/BdrTcb CONVERTTOV5 | NOCONVERTTOV5 Specifies whether a zFS read/write file system is assigned the converttov5 attribute. If it is assigned the converttov5 attribute and the aggregate is a version 1.5 aggregate, zFS automatically converts directories from v4 to extended (v5) as they are accessed. If the converttov5 attribute is assigned at primary mount time, a version 1.4 aggregate is changed to a version 1.5 aggregate. If automatic directory conversion for a directory fails, the conversion is not attempted again until the file system is unmounted and mounted again. The converttov5 attribute can also be assigned if the MOUNT option is not specified but the converttov5 specification in the IOEFSPRM file is on when the file system is mounted or remounted. The default is NOCONVERTTOV5. However, the converttov5 attribute can also be assigned if the converttov5 specification in the IOEFSPRM file is on when the file system is mounted or remounted.
