ONCplus B.11.31.03 Release Notes

server, can traverse the file system “/a/b” on the server without mounting the file system
explicitly.
• Referrals and Multi-server Namespace
The Cross Mount Traversal feature allows an NFSv4 client to traverse the servers shared
directories and seamlessly cross the physical file system boundaries on the server. The
Referrals feature allows an NFSv4 client to traverse shared directories and seamlessly cross
the physical file systems located on different servers. In other words, a referral defines a
way for the NFSv4 server to direct an NFSv4 client to a file system which resides on a different
server. The combination of cross mounts and referrals can be used to construct a global
namespace.
For additional details on these new NFS features, please see the Introducing Network File
systems Version 4 on HP-UX 11iv3 white paper at: http://docs.hp.com/en/
