Using the z/OS File System (zFS)

zFS is a UNIX file system. It contains files and directories that can be accessed with APIs. They can also be mounted into the z/OS® UNIX hierarchy along with other local or remote file systems types such as TFS and NFS. Use the ZFS file system type when installing z/OS or as the root file system.

You can use ISPF panels to create and manage the zFS file system. For more information about working in the ISPF shell, see Invoking the ISPF shell in z/OS UNIX System Services User's Guide.

The automount facility can be used for zFS, as described in Automounting zFS file systems.

You can set up read-only basic partitioned access method (BPAM) access to zFS files. Each zFS directory is treated as if it were a PDSE or PDS directory. For more information about BPAM, see Reading UNIX files using BPAM in z/OS DFSMS Using Data Sets.

For more information about setting up and using zFS, see z/OS File System Administration.
