Chapter 3 Managing ITP Networks Using SGM
Discovering the Network
If you run Discovery with Entire Network cleared, then you run Discovery with
Entire Network selected, any Unmanaged nodes in the first Discovery are not
rediscovered by the second Discovery.
To recover from this situation and generate a new, complete, and reliable SGM
database, you must perform one of the following procedures:
a. Run Discovery again, with both Entire Network and Delete Existing Data
selected.
b. Change the Unmanaged nodes to managed status. See the “Unmanaging and
Managing a Node” section on page 3-133 for more information.
c. Poll the nodes that were Unmanaged in the first Discovery. See the “Polling
a Node” section on page 3-134 for more information.
Step 7 (Optional) Specify whether SGM is to keep or delete the existing database when
discovering the network:
• To keep all existing network data in the SGM database before rediscovering
the network, clear the Delete Existing Data checkbox. This is the default
setting. Clear this checkbox when you run Discovery for the very first time.
• To delete all existing network data from the SGM database before
rediscovering the network, select the Delete Existing Data checkbox.
Choose this option if you know that network elements have been deleted from
your network since the last Discovery.
Note If you discover the network with Delete Existing Data selected, SGM
stops any real-time polls that are running and issues appropriate
messages.
