Storage Device node
The model of a storage entity consists of a central Storage System node, and associated Storage pools, Storage volumes, Storage processors, Front end FC ports, and Storage connections. Directly discovered storage entities also have a Storage Device node. The Storage Device node can be regarded in much the same way as the SI representing the storage management software. They are the trigger for the discovery of the storage entity rather than an integral component.
Creation/update
A Storage Device node is created or updated when a storage device is discovered either through discovery of the WBEM/SMI-S provider in the storage chassis, or a NetApp device is discovered using SNMP.
Removal
The removal of a Storage Device node is governed by aging in the same way as Host nodes.
When a Storage Device node is removed, all of the nodes it contains are removed. This is Containment Removal, see Containment Removal.
