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.

Host Info node attributes

The attributes and relationships of a Host Info node are described in the table below.
