Hello. 

   I am using a Solaris 8 machine and working with an NFS remote file
system, when trying to copy big files to the NFS file system I am
getting the next errors :

NFS write failed for server shlight: error 5 (RPC: Timed out)
NFS write failed for server shlight: error 5 (RPC: Timed out)
NFS write failed for server shlight: error 5 (RPC: Timed out)
cp: /export/home/prod/import/a.tar: write: Connection timed out

I have a slow connection to the NFS server, I think that this is
causing my problems, is there a way to tell the NFS client on my
Solaris machine to use a bigger time out before aborting the operation
with en error ?

TX. 
    hagai.

See
man mount_nfs

Promising is e.g.

mount -o proto=udp,retrans=10,timeo=600,rsize=8192,wsize=8192,retry=20000
....

Maybe one of these is already enough, try it out!

Don't mount with "soft".

In my experience with soft mounts the timeouts are never long enough.

So use hard mounts and your troubles are gone.

"hard,intr" (the default) does work well for mounts like these: you can
still bail out (intr) but you won't get corruption (hard).

Surely you don't want the mount to be both slow *and* unreliable?
