NFS mount to tru64 5.1 from HP-UX 11iv3

I'm stumped...I have a tru64 5.1b host. I'm trying to mount a filesystem from an HP-UX 11iv3 server.

from the tru64 client:

client # rpcinfo -p server
program vers proto port
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper

100227 3 tcp 2049
100005 3 tcp 56219 mountd

apps-raos # showmount -e server
Exports list on server:
/scratch Everyone

Now here's the strange part:

mount server:/scratch /scratch
Cannot talk to mount server at cadprd01: RPC: Timed out

What am I missing?

Actual output from:
sizer -v
and/or:
dupatch -track -type patch_level | grep 'Patch Kit'
could be interesting.

I don't know. Around here, I use the
automounter with no particular trouble.

Any chance that you have some firewall (or
other access restrictions) blocking the RPC
traffic between these guys?

Hello,
Did you also try using the ip@ of the NFS server ? And did it also fails or not?
You must first check if the tcp/ip Host Name Resolution is working or not. Please also check first /etc/hosts, resolv.conf, nsswitch.conf files too and etc..

Here is assuming your node is not a cluster member...You may check that also with
# hwmgr -view cluster

Re: NFS mount to tru64 5.1 from HP-UX 11iv3

My tru64 node IS part of a cluster. Not sure if that matters. I have verified name resolution. If I use the IP address, I see the same results.

Re: NFS mount to tru64 5.1 from HP-UX 11iv3

Hi Thomas,

I would sanity check the name resolution...

Based on your original output, I'm not sure whether you've tried to mask some of the real hostnames from the output, or whether "server" and "client" exist as real names, either in hosts or DNS...

Regards,

Rob

Thomas,
Did you put IP address of default cluster alias in /etc/export file on HP-UX machine?

Re: NFS mount to tru64 5.1 from HP-UX 11iv3

I did not do anything with the default IP of the cluster. I fail to see why that would be relevent, since the cluster node is just an NFS client. Please explain - I realize that trucluster can complicate some things.

Thanks.

Re: NFS mount to tru64 5.1 from HP-UX 11iv3

The outbound traffic from the client to the server might not be going out on the interface that you think it is...

Do the log files on the server yield any clues ?

Cheers,
Rob

Re: NFS mount to tru64 5.1 from HP-UX 11iv3

Rob, to simplify things, I have exported the server filesystem to any client. (filesystem is empty now - for test purposes).

If showmount -e (run from the client) shows the exported filesystem on the server, wouldn't that imply that the Tru64 client should be able to mount it?

Re: NFS mount to tru64 5.1 from HP-UX 11iv3

I've never used showmount, so can't really comment, however a quick test on a couple of Linux boxes I've got handy appears to suggest that showmount -e just lists what is exported, not whether the shares are actually mountable...

Did you get anything from the HP-UX log files ?

Cheers,
Rob
