VM TCP/IP NFS Server Support

The Network File System (NFS) server support enables access to files stored on VM's native UNIX* file system (the Byte File System), the VM Shared File System and CMS minidisks from any platform with an NFS Client.


NFS server support is packaged with z/VM in all supported releases. In z/VM Version 3, Release 1.0 (TCP/IP level 3A0) it was packaged as a separate feature.


How can VM's NFS server support benefit me?

  • Keep your data on VM, but use your BFS, SFS, or minidisk files transparently from any platform that has an NFS client.
  • Data is available across many platforms, without duplication.
  • Enjoy all the advantages of keeping your data on VM!
    • Automatic, secure facilities to back up and recover data
    • System managed storage
    • Host access control
    • Centralized space administration

Okay, how do I get started?


Interested in ancient history? See a description of release-to-release NFS changes for TCP/IP level 420 for z/VM Version 4, Release 2.0 and TCP/IP level 410 for z/VM Version 4, Release 1.0 and TCP/IP level 3A0 for z/VM Version 3, Release 1.0 and TCP/IP level 320 for VM/ESA Version 2, Release 4.0 and TCP/IP level 310 for VM/ESA Version 2, release 3.0.
With VM/ESA Version 2 Release 3.0, TCP/IP and the Network File System (NFS) server feature of TCP/IP became optional priced features of VM/ESA.

Other NFS clients should be able to use our NFS server support, although mount procedures may differ from those described above.
