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. Have you used NFS clients on other platforms with our server? Tell us about them. If you have any other comments on these instructions, send a note to Mary Ellen Carollo, maryelln@us.ibm.com.
