Re: [NV-L] NetView Discovery Issues

[Mike Pearson <pearsom@us.ibm.com>]

Hi Stephanie:
        That
pmr is long gone.  I have searched for it.  I can't really open
a pmr unless I have one to copy the information from.  We do not have
access to customer data, only through an open pmr.  If you could open
it and ask for me, I will work it with you.
Thanks

Regards, 
Michael Pearson

Mike,
Can you open a PMR on this?  The last PMR I opened
was PMR 91969.  My work email address and contact number should still
be in your system.

Leslie, 
My seed file includes routers and switches.  I ran ovobjprint and
ovtopodump to search for the first 3 octects of the IP addresses.  I
turned netmon trace on with a -1 trace mask value.  I've tried forcing
NetView to discover these devices by doing an extended ping from the command
line.  Here's some output from netmon.trace: 
  
14:49:27 : ./nl_pinger.c[1519] : revc_icmp: deleteMatchIp returns null!
14:49:23 : ./nl_hint.c[295] : Addhint(172.18.117.130,0.0.0.0) Best guess
network is <null>
14:49:23 : ./nl_hint.c[306] : Addhint(172.18.117.130,0.0.0.0) rejected
(no network for IP addr)
14:49:23 : ./nl_pinger.c[1559] : -> received unexpected ping, ident=8909
seq=33, from 172.18.117.130 

I ran "ovtopofix -a" and have the rw map. 
  
I've done everything possible to get these devices discovered.  What
are your thoughts?

You don't even need SNMP access to get them discovered. So something more
basic is wrong. 
Is this a Unix or a Windows server? 

Check these things: 
1) If you are using a seedfile, does it exclude the range of addresses
that you are trying to discover? 
2) Have you tried putting the router and switch addresses in the seedfile?
3) Is the map you are looking for them in a r/w map up?
4) Are you sure they are not in there already, maybe on some other node
than you expect? 

For that last one, try 
nvUtil e '("SNMP ipAddress" = "xx.xx.xx.xx")'

5) Remember that a range in the seedfile only allows discovery, it does
not force discovery. If they are found in the arp cache of an existing
device, and they are allowed by the seedfile, they should be discovered.

6) Be sure you are not discovering by a virtual address. Try using the
loopback address of the device. To tell if you are using a virtual, try

  rnetstat -Ix xx.xx.xx.xx 
and check the output to see if that address is in the list of addresses
on the device. If it is missing, Netview will discard the node. 

7) If you have more than one map, and the things were previously discovered
in one of them, they must be deleted from all maps before they can be rediscovered.

8) Do these commands to reorg things that might have gotten out of wack:
  ovstop netmon 
  ovtopofix -a 
  ovmapcount -a 
  ovstart netmon 
  close and open the map
Cordially,

Subject	[NV-L] NetView Discovery Issues

All, 
I have 2 routers and 2 switches on the same subnet which NetView 7.1.4
won't discover.  Each device is reachable via Ping and each one responds
to SNMP polls. 
 
Can someone let me know which MIB objects NetView reads and uses in order
to add new subnets and /or devices? 
 
Thanks In Advance, 
Stephanie
