Any ideas on what the error listed above means would be great.

Re: NFS Read/write issues...
Have you looked aat syslog /var/adm/syslog/syslog.log
Is there anything else to help.
As far as I can tell without background, there is nothing in the error output to lead to the read write issue, which is not clearly defined or referred to in your thread.
Most NFS issues either deal with Network connectivity, as in the switch the wire, the configuraiton, the NIC card, or permissions.
If permissions is not an issue, run cstm or mstm or xstm diagnostics on the NIC card and see if there are a lot of problems on the switch concerning this host.
Also, make sure always you have the latest, greatest and best NFS patches on your system along with dependencies.

Re: NFS Read/write issues...
which protocol are you using to access the NFS mountpoint ? UDP or TCP. If it is UDP, and if you can try TCP as it provides a little slower but more robust access.
Also, check to see if your network interfaces' firmware revisions are upto date.

Permissions do not appear to be the problem.

Re: NFS Read/write issues...
I have checked your previous posting abut the issue and you said you do not have control over the netapp, so I will not re-iterate my try TCP connectivity instead suggestion, but if you have any way to talk to the admins of the netapp box, try convincing them to turn on TCP connectivity, just for the testing if not for permanent, so that you can diagnose the problem. If that fails, ask your network administrator folks to place a sniffer to this network segment and try to find out what exactly is happening at this RPC timeout moments.
Other than that, I don't know what else to suggest.

Re: NFS Read/write issues...
I just saw this post (I only check ITRC once ever couple of weeks when I get really busy at work). Are you still having this problem or have you figured out the root cause? If you're still having the problem let me know and I can try to help you troubleshoot it further.

Re: NFS Read/write issues...
This problem has popped up once again.
Any ideas on how i can fix it?
Last time it was due to the NFS server having two NICs and i was trying to mount against the wrong one but, thats not the case now.
Any ideas would be greatly appreciated.

Re: NFS Read/write issues...
Well, isn't this a blast from the past? Nearly a year between responses. :)
Let's refresh a bit here. What OS is the NFS client running? What OS is the NFS server running? What NFS patch levels are both of them running? On the NFS client issue the command "nfsstat -m" and post the output so I can see exactly how the filesystem is mounted.
Is this a problem that happens once a year or is it reproducible? If so, what steps are you using to reproduce the problem? If you can reproduce it at will I'd suggest starting a network trace and capturing one of these events in the trace. Hopefully the trace will provide some hints as to the reason for the error.

Dave

Re: NFS Read/write issues...
I think its a network connectivity issue...
First check whether servers are reachable..
then also check nfs status on both servers.

Re: NFS Read/write issues...
IE HP server located in the smae building is successfully mounting the export from the server.
However copying the exact mount references from the /etc/fstab still gets the errors.
I have checked networking to verify that the Lan card is mounting at 100FD.
Any other ideas?

SolutionYou haven't answered any of the questions in my previous post. Please answer those and also cut/paste the exact command you're using to reproduce the problem and the exact error message you're getting.
