4.3.2 Tips for configuring seeds

If you already have a file that lists the nodes to be discovered, format this information as a seed file and use the nnmloadseeds.ovpl command to import the node list into NNMi.
In the seed file, specify IP addresses as a way of influencing the IP address that NNMi chooses as the management address. (If you use host names, DNS provides the IP address for each node.)

Formats for the entries in the seed file are as follows:

IP_address # node name
IP_address2, "tenant-name-or-tenant-UUID" # node name

For maintenance purposes, it is better to use only one seed file. Add nodes as needed and then rerun the nnmloadseeds.ovpl command. NNMi discovers the new nodes but does not re-evaluate the existing nodes.
Removing a node from the seed file does not remove it from the NNMi topology. Delete the node directly on the NNMi console.
Deleting a node from a map or inventory view does not delete the seed.
If you want NNMi to rediscover a node, delete that node from a map or inventory view and from the Seeds view in the Discovery area of the Configuration workspace on the NNMi console, and then re-enter the node on the Discovery Seed form on the NNMi console, or run the nnmloadseeds.ovpl command.

Rule-based discovery only: Completely configure a discovery rule before you specify a seed for that rule. That is, click Save and Close on the Discovery Configuration form. (When you save the information on the Discovery Seed form, NNMi updates the seed configuration immediately.)
