OpenVMS 8.5 NFS client
OpenVMS 8.5 NFS client
I am attempting to mount an nfs share hosted on a netapp to my VMS system. When i issue the mount command i get an error message stating that "network object is unknown at remote node" I have also attempt this when connecting to a RHEL8 nfs server and get the same error. If i try to mount something that has not been exported i get the error that I would expect "file not found"
I have scoured the net high and low and can not find anything that will point me in the right direction to figure this out. I am a newbie with VMS and inherited this system so I am learning as I go.

Re: OpenVMS 8.5 NFS client
to start with, give us some hints. perhaps sharing your OpenVMS and TCPIP versions along with the actual tcpip mount command that you're using with the actual error messages.lobout wrote: ↑Thu Jan 23, 2025 5:01 pmI am attempting to mount an nfs share hosted on a netapp to my VMS system.

Re: OpenVMS 8.5 NFS client
As the subject says it is OpenVMS 8.5 running on itanium hardware. tcpip is version 5.7. i'm not doing anything special with the mount command. i have a proxy user set up and am mounting with the following:
mount dnfs0: /path=”/<path>” /host=”<hostname>” /structure=5 /system
when doing this towards my linux nfs server I see a mount authentication request then a umount request. If i change the path to a mount that is not exported I get the expected error of file not found, but when pointed to a legit export i get the network object unknown message.

Re: OpenVMS 8.5 NFS client
The latest release of VMS for Integrity platform is V8.4-2l3; version 8.5 never released !
I would suggest you get more precise information about your software environment, including the hw platform and the patch level of OS and TCP/IP stack.

So plain V5.7 on Itanium 8.4. I assume the TCPIP_NFS_PAT V5.7ECO5C is not installed.
In that case add
/noafd
to the mount command

/noafd

Re: OpenVMS 8.5 NFS client
Thank you I will try that. Like I said I am still trying to come up to speed on VMS. I played with it a little well over 20 years ago, but don't know much about it. i'm a linux guy, so I understand a lot of the theory behind it, but just learning the OS has been a major curve for me.

so i get the same error message when using the /noafd switch. and yes you are correct it appears to be plain openvms 8.4 with tcpip 5.7. no other patches appear to be applied.

Re: OpenVMS 8.5 NFS client
TCPIP 5.7 with no patches seems a poor starting point. For sure update to 5.7-latest ECO patch kits before proceeding.
after that... there are two potential transports (UDP and TCP). Try both; some servers don't do one or the other by default. also the

Ok so If I can go down that route, how does one obtain the patch kit, and how do you apply it?lastovica@sciinc.com wrote: ↑Fri Jan 24, 2025 9:26 amTCPIP 5.7 with no patches seems a poor starting point. For sure update to 5.7-latest ECO patch kits before proceeding.

Re: OpenVMS 8.5 NFS client
get in touch with your software vendor. they'll presumably be able to supply you with the current TCPIP ECO kit(s) along with the release notes and installation instructions.

Also please share with us the output from "pipe ucx sho ver/all | sea sys$input nfs ; prod sho hist *TCP*"
