ptx®/NFS® V4.6.5 is a subset of Sun Microsystems® NFSSRC V4.2, ported and enhanced to run on IBM® NUMA 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:

The following sections list open and fixed software defects in this release of ptx/NFS:
The following software defects are fixed in this release of ptx/NFS:
(223763) The ptx/ADMIN Change NFS Mount Entry form was always drawn with the automount option set to"Y" and the comments field cleared.
(239314) When an automount was created through the ptx/ADMIN menu system for direct or indirect maps, the option for the type of mount was positionally dependent.
(241176) The system panicked when creat(), unlink(), chmod() and chown() were run in parallel on a file on an NFS-mounted filesystem.
(248292) rpc.rstatd passed an incorrect buffer size to getkerndata, which resulted in warning error messages.
(253956) ptx/NFS was continuously writing "host down" messages to the log.
(253977) An error in the ptx/ADMIN NFS menus resulted in a filesystem export with anon=root.
(255257) While the system was reading from an NFS file that was memory mapped, ptx/NFS returned extra zero bytes.
(255441) When a file was successfully mounted from an exported VM filesystem, the first ls command on the mounted filesystem was successful. All subsequent ls operations failed.
(255523) ptx/NFS had the wrong owner and group for /usr/sbin.
This section lists open problems in this release of ptx/NFS:
The ptx/ADMIN menus used to manage the automounter maps create file names with periods instead of underscores, creating /etc/auto.master instead of /etc/auto_master.
Workaround. None.
ptx/ADMIN returns an error when a user tries to add more than 10 hosts in the "Enter list of hosts to export this filesystem read/write to" section of the "Exported filesystems" menu. The error is:
Too many members in the read/write group
Must be less than 10. Operation aborted.
Workaround. If you wish to place more than 10 hosts in the read/write group, edit the /etc/exports file manually and then run exportfs.
The automounter is not able to read maps from NIS servers.
Workaround. None.
rpcinfo is unable to communicate with previous versions of the portmapper.
Workaround. None.
The mount_nfs command returns a 0 exit status when it fails because the mount point is already in use. This can cause problems when mount_nfs is used by shell scripts that try to verify whether the command was successful.
Workaround. None.
ptx/NFS limits itself to one-half the total buffer cache. This does not work correctly on multiquad systems, where one quad can run out of buffers.
Workaround. None.
The mount_nfs command does not validate the options that are passed to it and passes bad options to /etc/mnttab.
Workaround. None.
Environment macro expansion in the automounter does not work correctly.
Workaround. None.
One of the options in the automounter is to start up the automounter server with a known port number and replace a crashed automounter with the same port number. However, the automounter refuses to start up with the -p option.
Workaround. None.
The -f, -p, and -l options to the automount command are not documented in the man page.
Workaround. None.
Comments in the auto.master file are not ignored by the automounter, which results in errors in the ktlog.
Workaround. None.
