HP Netsight manual NEW and Secondary Discovers, Stopping a Discover in Progress

Discovering Nodes

NEW and SECONDARY Discovers

Discovery sessions are divided into two types: NEW and SECONDARY. The first time you run a device discover script, all IP addresses in the subnet or address range you have specified will be queried, and all discovered devices will be listed in the discover window and automatically added to the central node database. This is called a NEW Discovery. The second time you run any device discover, however — even a device script which has not yet been run — NetSight Element Manager will perform a SECONDARY Discover, querying only those IP addresses which did not respond to the first discover.

When a NEW Discovery is performed, new information which may be discovered about an

TIP IP address will not overwrite the information about that address which is currently in the central node database. For example, if an IP address previously assigned to an EMME is moved to a SmartSwitch 6000, the discover application does not record this change in the database.
