Configuring NFS timeouts

Hello Tru64 Managers,

Have been having problems with NFS timeouts mounting DVDs in a jukebox via
NFS3. The DVD takes about 30 seconds to load, during that time you get:

NFS3 server localhost not responding still trying
NFS3 server localhost ok

messages on the screen and in the system log. Tried setting 'timeo=600' as
suggested by mount(8) but that doesn't seem to work. See below for further
details. Any suggestions?

                Sorry, on Tru64 we do not know, or think there is a way to
change NFS
                (loopback) time outs.
                On other Operating Systems timeo value seems to work fine
but not on Tru64.
                So you are going to see "NFS3 not responding / OK" messages
in your system
                log.

                Problem Title: MagnaVault 227: NFS3 server
localhost not
                responding still trying

                Problem Description:

                When loading a DVD into a jukebox drive, the messages:

                NFS3 server localhost not responding still trying
                NFS3 server localhost ok

                appear on the screen and in the system error log(s).

                You should be able to overcome this by modifying /etc/xfstab
from:

                JAM04001 11df11df.886aaa1a udf 0 1 rw,auto,rdirid=400008b -
0 - 0 -
                /jb/JAM04001
                to:
                JAM04001 11df11df.886aaa1a udf 0 1
rw,auto,timeo=600,rdirid=400008b - 0 - 0
                - /jb/JAM04001

                either directly or via /opt/bakbone/bin/xfstab -o. See
mount(8) for details.

                But it doesn't work. Please advise how to configure NFS
timeouts for DVDs.
