I tried James's suggestion and was able to get NV to discover my new nodes.

James,
Thank you for your support. Adding an Address from a range, is exactly what I
did, but these where the only nodes NV discovered yet. I started NV without
seedfile now, but didn't get any nodes (couldn't even discover it self yet). So
i'll let it run this way tonight and let's see what happend. I guess the I have
to search the problem somwherre else than ins seedfiles.
I'll send you an update when the problem is solved (if you're intrested)

Adrian -
The first thing I will tell you is that I am not an expert in fixing discovery
problems, so I cannot comment on what you have done. I don't work in that area
of the product. All I can do is suggest what to do based on my understanding.
If you want further assistance you will have to open a problem to Support or ask
a question for other users to comment on here. But what I am suggesting is that
you put in the seed file, in addition to the address range, a few actual nodes
in those subnets. When you put a node by hostname or IP address in the seed
file you are telling netmon that you absolutely must have this node discovered
and put on the map (if at all possible). That will force him to go out and find
it if he can.
So for your range 192.168.10.4-253, pick a node in the first subnet, let us say
192.168.10.9 for example, and put him in the seed file and restart netmon. If
you have 5.1.1or later you can issue netmon -y and he will re-read the
seedfile without a restart. Finding nodes in the seed file is the first thing
netmon does after loading the topology and doing his config checks, so it should
make a difference very quickly. If you have success with this, then follow the
same procedure and add one node from each subnet. Once those are found the
others in each subnet will follow very quickly. Note that I am not suggesting
that you add all the nodes, just one from each subnet.

James,
sorry, this stupid question, but do you mean I just have to add such an address
in the seedfile? If so, I have to tell you that I already did, but netview just
got a single address yet (in 72 hours). Because of the arp cache thing, NV
discovered all routerinterfaces connecting to these ranges, so I think there
should be enough of arp informations aviable there. I also searched in all
aviable documentations, and it seems that I did everything the way it's written
there.
Should I add the router interfaces for each range seperately?

A range does not guarantee discovery, but rather limits it to addresses within
the range. You will want to add the IP addresses of at least one actual machine
in the subnets which you haven't found yet. New node discovery works on the
principle that the arp cache of known machines will contain addresses of unknown
ones.
You might want to review the on-line doc on seed files, just type in dtext from
the command line, assuming you have sourced the Tivoli environment ( .
/etc/Tivoli/setup_env.sh ) first. You can search all the books dynamically but
most of what you want is in NetView Installation and Configuration.

Subject: using IP ranges in seedfile
Hi,
I'm a newbie on this list, but already have a question. We have several NV
installations, all using seedfiles, and all works fine. But on a new
installation we tried to use ip ranges (192.168.10.4-253) in the seedfile. The
problem is, that it dosvered just 2 ranges which are in the seedfile.
any suggestions?
Thanks
Adrian
