Host Container node

A Host Container node is used to model a system that is logically partitioned into a number of hosts, but is not a directly discoverable host itself. Systems that contain a number of physically separate devices, such as blade enclosures, are modeled as a Hardware-Container-node.

Host Container nodes always have a relationship to the Pattern node corresponding to their maintaining pattern.

Host Container Lifecycle

The following section describes the scenarios in which a Host Container is created, updated or removed.

Creation

Host Containers are created when a pattern discovers conditions which enable it to detect a contained host. Once found, the pattern creates the Host Container that it needs. A relationship link is automatically created to the Host node and the Host Container will have a key generated. The generated key for a Host Container node is entirely dependent on the type of Host Container.

Update

The update procedure for a Host Container is also under full control of patterns. When the pattern has identified a contained host, a key is generated for the Host Container. If a Host Container with that key already exists, the Host Container is updated accordingly.

Removal

The default destruction of a Host Container is not under the control of patterns. A Host Container node is removed when the last remaining contained Host node is unlinked and there is no longer any evidence for that host or any of its relationships, for example, to network devices, management controllers or any other root node kind. This is a Cascade Removal type, see Cascade Removal.
