The z/OS NFS client supports servers that implement the server portion of the Sun NFS Version 2, Version 3, and Version 4 protocols:

• z/OS NFS Server
• Linux
  • Red Hat EL 5
    • Intel x86
    • PPC64
    • z/Linux
  • Suse SLES 11.2
    • Intel x86
    • PPC64
    • z/Linux
• AIX®
  • 6.1
  • 7.1
• Sun Solaris version 10
  • Sparc
  • X86_64
• Windows/OpenText
  • Windows XP
    • OpenText Maestro™ 2008
  • Windows 7
    • OpenText NFS 14
  Note:

  1. Older versions of these servers are still supported under the NFS version 2, version 3, and version 4 protocols, but not all have been tested by IBM®.
• Other server platforms should work as well, since NFS is an industry standard protocol, but have not been tested by IBM.

A mount parameter vers(x), where x is either 2, 3, or 4 is provided to make the z/OS NFS client communicate with the server at the specified protocol level. The z/OS NFS client also communicates at the highest protocol level that is supported by the server if no level is specified.

• If no version is specified and if the server supports:
  • Only the NFS version 2 protocol, then the z/OS NFS client will use the NFS version 2 protocol to communicate
  • The NFS version 2 and 3 protocols, then the z/OS NFS client will use the NFS version 3 protocol to communicate
  • The NFS version 2, 3 and 4 protocols, then the z/OS NFS client will use the NFS version 4 protocol to communicate.
• If vers(2) is specified, then use NFS version 2 protocol to communicate with the server.
• If vers(3) is specified, then use NFS version 3 protocol to communicate with the server. z/OS NFS client fails the mount command if the server does not support NFS version 3 protocol.
• If vers(4) is specified, then use NFS version 4 protocol to communicate with the server. z/OS NFS client fails the mount command if the server does not support NFS version 4 protocol.
