What a good idea. It's my favorite thing to do. Yes, use the one that saves
customizations. It saves smartset definitions and apm stuff if you have
any.
If you are using the location.conf file, make sure it is up to date, so as
to avoid
the problems that have been discussed here lately. And of course double
check your seedfile and name resolution. I suggest you order your seedfile,
routers first, near to far, keep it fairly short. Deal with the hubs later,
for instance.
And don't put any non-snmp things in the seedfile if you can help it.
Note that if you have been using the Turbo form, say because you have a few
devices with interface counts over about 70, then you will have to redo the
Turbo conversion after the rediscovery to get those devices discovered
correctly. In those cases, I start with a short seedfile, stop the
discovery, and
convert before proceeding.
A good thing to do at this point, when you have too much stuff, is to
extract
from it a list of what you DO have, so you can make sure you get it all
back, if
you want it. Use ovtopodump -rl > topo.file to save it for later. Then you
can
use little scripts to pull all of the routers, or all of the devices by
oid, or whatever.
Backups before and after, of course. And neatness counts!
Cordially,

Subject: [NV-L] How to clean the database up?
Hi. We are running NV 6.0.2 on AIX 4.3.3.
I would like to "destroy" the database(s) and have Netview rediscover our
network. It appears that under the "server setup" dialog, there are two
options called "Clear object/topology/map databases" that would do the
trick, one saves customizations, one doesn't. I don't want to destroy my
smartset definitions or rulesets, but otherwise would like Netview to
behave as if it was just installed and knew nothing about our network.
So, would the "save customization" version of this be what I want, or is
there a better way?
Some things I'm seeing that are driving me toward this are:
* Netview refuses to discover anything new. (eg, Netview is missing
hundreds of hubs, and no matter what I do, it won't discover them)
* We swapped some switch hardware, which Netview recognized just fine, by
updating the objects and symbols. I cut the objects from the map and tried
to paste them into a new container, but they came back with "shadows". I
deleted them and can't get them back.
* Netview discovered some of our routers as multiple routers, rather than
one router with multiple interfaces.
* Netview knows about plenty of objects it shouldn't right now. Probably
due to not having the correct seed file filters on during a discovery that
happened a long time ago.
This seems like the easiest, quickest way for me to try to get this cleaned
up.
Other opinions and input are welcomed.
Thanks.
