6.4.2 Checking for discovery of all seeds

  1. Open the Seeds view.

  2. On the Seeds view, sort the list of nodes by the Discovery Seed Results column.

    For any node in an error state, consider the following:

    • Failed discovery due to an unreachable node or unresolved DNS name -- For these types of failures, verify network connectivity to the node and check for accurate DNS name resolution. To work around DNS issues, use the IP address to seed the node or include the host name in a hostnolookup.conf file.

      If a name cannot be resolved due to the IP address, include the corresponding IP address in the ipnolookup.conf file. For details, see the reference pages for hostnolookup.conf and ipnolookup.conf.

    • License node count exceeded -- This scenario occurs when the number of devices already discovered has reached your license limit. You can either delete some discovered nodes or purchase additional node pack licenses.

      When tracking license information, note the following:

      • Consumption: NNMi discovers and manages nodes up to the NNMi licensed capacity limit (rounded up):

      • VMware environments: Each device with a Device Profile of vmwareVM is equivalent to 1/10th node.

        All other devices are equivalent to one discovered node.

    • Node discovered but no SNMP response -- SNMP communication problems can occur for seeded devices as well as for devices that are discovered through auto-discovery. For details, see 5.4 Evaluating communications.
