What is happening probably is that the client is making a tcp connection
back to the backup server which then sits idle until the backup is
finished.   If a saveset takes longer to backup than the usual firewall
default tcp seesion timeout that session will be dropped by the firewall
and the success of the backup will not be communicated to the savegroup
process...

There are two approaches to solving this:

1. increase default TCP sesssion timeout on the firewall to be long
enough.

2. reduce the tcp_keepalive interval on the backup server to be less
than the TCP session timout on the firewall..

Subject: [Networker] Backups status not finishing

Hi folks,

I would just like to know if somebody in this forum has already
encountered this problem that we are currently experiencing. We have our
backups running smoothly until we migrated some of our clients and one
of our storage nodes to a new IP address with a firewall in between
them. Initially, our problems were concerning DNS resolutions but we
were able to resolve it now, it seems.

Now, although the data on the disks are being being saved to tape and
can be browsed using nwrecover, and the tape drives are being released,
our backup's status on the nwadmin's group control window continous to
be RUNNING and what we'll need to do is to manually stop it so that the
next backup will run as scheduled. Then, that's the time that we will
only get the email notification for a failed completion.

We've already raised a case with EMC on this and currently, we are
setting up a test server to do some isolation tests based on their
suggestions.

Our Networker server is v7.2 on Solaris 9, and our affected clients and
storage node are on OpenVMS v7.3-2/TCPIP v5.4 ECO5, with Networker
v6.01-D ECO13.
