Host Info node

A Host Info node contains information about the kind of host and some of its physical characteristics. If BMC Discovery decides that there is not sufficient information available to create a Host node, the Host Info node captures and stores the available information.

Host Info Lifecycle

The following section describes the scenarios in which a Host Info node is created or destroyed. DDD nodes are never updated.

Creation

Whenever BMC Discovery scans an IP address, a Discovery Access node is created. If there is any response to the scan a Host Info node is also created. The level of information in the Host Info node varies depending on the discovered device.

Removal

A Host Info node is removed when the Discovery Access node which it is associated with has been destroyed through the Aging process.
