The discovery process relies on the local name resolution service to complete the following three tasks:

  • For manual discovery, resolve the hostnames of discovery candidate systems to corresponding IP addresses so that the systems can be discovered.

  • For manual discovery, resolve the IP addresses of discovered systems to corresponding hostnames so that the discovered systems are given unique names within the topology.

  • For autodiscovery, resolve the IP addresses of discovered systems to corresponding hostnames so that:

    • Hostnames can be matched against the “System Name” field in the discovery filters that are described in “Creating discovery filters” on page 88.

    • Discovered systems that pass the discovery filters are given unique names within the topology.

      Until a system is discovered, it is known to the discovery process by its IP address only. When the system is discovered, the discovery process makes calls to the local name resolution service and runs a script to assign the system a distinct and meaningful name.
