ptx®/NFS® V4.7.1 is a subset of Sun Microsystems.® NFSSRC V3 based on ONC+ 2.1, ported and enhanced to run on IBM® NUMA-Q® and Symmetry® systems. It supports filesystems larger than 2 GB and files up to 2 GB.
This version of ptx/NFS requires the following products:

This release of ptx/NFS is a follow-up release to ptx/NFS V4.7.0, IBM NUMA-Q's initial release of NFS Protocol V3 based on ONC+ v2.1 source code from SunSoft. ptx/NFS V4.7.0 and V4.7.1 include:
64-bit file sizes and offsets to support larger files and filesystems.
Performance enhancements due to a decrease in the number of over-the-wire transfers, use of the uncommitted write command, and by relaxing transfer size limitations.
This release of ptx/NFS supports the "vers" argument to the "-o" option of the mount command. This optional argument lets you specify either 2 or 3, for versions 2 and 3 of NFS Protocol V2 and V3, respectively. If you do not specify the version argument, ptx/NFS will use the NFS version of the system you are mounting to.
For information on installing ptx/NFS, refer to the DYNIX/ptx and Layered Products Software Installation Release Notes.

This section lists fixed and open software defects that have been reported against this release of ptx/NFS.
(249640) ptx/NFS did not handle rfscall commit failures by resending the data; now it does.
(246156) A file could not be opened when the mandatory lock bit was set in permissions.
(245694) After running for several hours, the automounter failed and dumped core.
(251007) ptx/NFS automount clients failed to mount hosts for indirect host table maps.
(250579) A CPU stall occurred during an NFS unmount operation.
(250521) /bin/pwd returned the wrong path name for ptx/NFS mount points.
(249831) A regular file could be NFS mounted but not unmounted, causing the system to panic during shutdown.
(249818) The lockdump utility did not work correctly.
(248820) A ptx/NFS forced umount operation was not working correctly because it did not delete old mount structures.
(247634) The nfsstat command did not provide NFSSRV 3 client-side data.
(223763) The "Change NFS Mount Entry" ptx/ADMIN menu form always set the automount option to "Y" and cleared the comment field.
This section lists open problems in this release of ptx/NFS. The numbers in parentheses identify the problems in the IBM NUMA-Q problem-tracking system.
Occasionally, for no apparent reason, the automounter dumps core.
Workaround: First, unmount all the automount /tmp mount points, and then restart the automounter.
The mount_nfs(1M) man page does not include a description of the new mount -o vers= option.
Workaround: None.
