Accessing z/OS

To access remote z/OS files, enter both the mvslogin command to log in to the NFS server's host system and the mount command to mount the files or data sets to your local system. The mvslogin command is only required when accessing data on systems where the NFS server site security attribute is set to saf or safexp. Once the files or data sets are mounted to a local mount point, you can read, write, create, delete and treat the mounted files as part of your local UNIX files. When you are finished with your work, use the unmount and mvslogout commands to break the connection. The mvslogout command is only required when the mvslogin command was used to begin the connection.

Note:

Issuing the mount and unmount commands, as well as creation of the mount point, must be performed by someone with superuser authority.
If the underlying z/OS UNIX file system structure should change due to the mount of a new HFS or zFS file system into the space accessible by an existing remote NFS Client mount, this change and new directory structure and contents will not be visible to the remote NFS Client until the NFS mount is unmounted and remounted or the z/OS NFS Server is restarted.

To access files on z/OS systems where the NFS server site security attribute is set to saf or safexp, you need a z/OS user ID and password, and authorization to access the files that you need. You can only establish one z/OS session for each z/OS user ID. If you do not already have an z/OS user ID, a z/OS password, and access authorization on the z/OS system from which you require NFS services, request them from your z/OS system administrator.

Note: If you cannot use the mvslogin, mvslogout, or showattr commands, they might be installed incorrectly. Ensure that your system administrator has made the executable code for these three commands available to your z/OS user ID and that you have been given the correct access authority to them.
