Beginning with z/OS® V1R11, the zFS file system owner can be different than the z/OS UNIX file system owner when zFS is running sysplex-aware. For an explanation on how to determine the owner of a zFS file system, see the topic on zFS ownership versus z/OS UNIX ownership of file systems in z/OS Distributed File Service zFS Administration. Instead of the typical commands used to determine the z/OS UNIX user (for example, df -v, D OMVS,F, or F BPXOINIT,FILESYS=D,ALL), the zfsadm lsaggr command is used.
