Hi,

The attribute caching parameters won't do anything for you since you are copying a file and not searching a directory.

An NFS connection timeout error is probably a soft NFS Mount timeout due to packet loss on the underlying network. Its possible that you are seeing Duplex mismatch on 100BaseT link or an unreliable link.

ITRC Document KBAN00000261, and NETUXKBRC00006283 both should give you tips to solve that underlying problem.

Hope this helps,

The devresource.hp.com pages have all changed. The NFS performance location is now:

Brian is right.

If you are getting NFS timeouts, then the network link is unreliable or, less likely, the source of the file or the target system to where the file is being moved is having file system troubles.

I would check the network link error counts first, and if they are low (should be nonexistent, e.g., 0) then check the system logs for the source NFS system and the target. If the source system and the target are the same, then you have but one system to check.
