nfs mount OpenVMS 8.3 -1H1 to windows 2012 nfs server

I am trying to mounting a device on my OpenVMS 8.3-1H1 (ia64)  machine to an NFS Server directory on a windows 2012 server.

 

OpenVMS tcpip version - 5.7 eco 4

 

mount command:

 tcpip mount DNFS2: /host=windows2012host.name.co.il  -
        /user=DEFAULT/uid=-2/gid=-2/path="/d/forms"   -
        /time=::59/noadf

 

the error message that I receive is

%TCPIP$DNFSMOUNT-E-MOUNTFAIL, error mounting _DNFS2:[000000]
-SYSTEM-E-NOMSG, Message number 000086EA

 

 

On the windows 2012 side the nfs share is setup for auth_sys and allow anonymous access.

Also, NFS permissions are set to ALL MACHINES read write.

 

what is the problem?

[ Edited ]

A wild guess, maybe this is not the complete VMS error code and it should be

DEMO$ set message sys$message:tcpip$msg

DEMO$ write sys$output f$mess("%x76486EA")

%TCPIP-E-NOTADIR, !AS is not a directory
DEMO$
which would make some sense in this context and which would mean that the specified /path value is not correct - not a directory.

Re: nfs mount OpenVMS 8.3 -1H1 to windows 2012 nfs server

That is a very interesting idea.

 

While I was looking for a solution I deliberately entered an invalid path and received the error message that you mentioned - "is not a directory". So I was assuming that my unclear message was something else.

 

I have also since discovered that I neglected to configure the "Identity Mapping Source"  with "Active directory domain name" in the "Services for NFS Properties" window on my windows server. (see attachment)

 

Now the following occurs.

 

The mount command succeeds. In the windows nfs event viewer I receive a log message "mount succeeded" but immediately following that I have another event viewer message "unmount succeeded".

 

And guess what, I can't access the directory from the OpenVMS server even though it looks to be mounted.

 

Any ideas?

Re: nfs mount OpenVMS 8.3 -1H1 to windows 2012 nfs server

Anthony,

 

have you correctly set up the UID/GID mapping ?

 

Every NFS request contains a UID/GID pair. On OpenVMS, this is obtained from the NFS proxies (TCPIP SHOW PROXY). So your OpenVMS user trying to access the NFS share needs to have a valid NFS PROXY entry for the NFS server host. Username and host name are used as a key to access the proxy database to obtain the UID/GID.

 

The same kind of UID/GID mapping to username will probably happen on Windows.

 

Volker.
