Errors when copying from HP-UX to Windows 2003 Storage Server

Paul Maglinger — Wed, 07 Jul 2010 15:09:46 GMT

We're running HP-UX 11.23 servers that have mounts to remote NFS shares on a Windows 2003 Storage Server machine. Not on every file, but occasionally we get an error similar to this:

128:cp: cannot create /source/recship.lis: I/O error

or sometimes we'll get this:

952:cp: cannot create /PdfRpt/Accounting/mis_415/mis_415_152_2010-07-02.pdf: Permission denied

After which we try recopying the file and it works okay. I have downloaded several documents on tuning NFS and have made the registry changes on the Windows server and it helped quite a bit, but we are still getting them about 10 times a day. The entries in the fstab look similar to this:

server.domain.com:/Source /source nfs retrans=10,timeo=14,rw,suid,hard,intr 0 0

Any other suggestions on where to look or what to try to eliminate these errors? I submitted this on the HP-UX forum and one response believes that the issue is still on the Windows side.

hi,

did you tried to use AutoFS ???

this is for 11.31 but i tbink it should be compatible for 11.23.

I'm not having an issue mounting to the share, but copying to it consistently. Just from what I read on the overview, this would only mount the share when needed and then unmount it afterwards. How would this improve the reliability of the copy process? Just asking.

hi,

yes you have right with the AutoFS, NFS is very well but if you have normal NFS mount soft/hard mounted it could happen, that if your server ( windows storage server ) is not respondig, your Unix server could hang, the Autofs is better option. As you already mentioned, the Storage server could be the reason why you recieve this error messages, check the event log for errors.

Yes, and I was simply following Steven Schweda's suggestion to post to the Windows Admin forum. I'm looking for any and all suggestions here.

Due to some clues given by those on the HP-UX thread, I think the problem has been corrected. I installed the Server for NFS Authentication component on all the domain controllers and the problem seems to have cleared up. Thanks to all.
