Storage Pool node
A Storage Pool node represents a block of storage from which storage volumes and other storage pools can be allocated. A storage system may expose one or more storage pools. Where there is a hierarchy of pools (Primordial -> Concrete), this is modeled using a Hierarchy relationship.
Creation/update
A Storage Pool node is created or updated when a storage pool is discovered as a result of:
- WBEM queries to storage management software triggered by the creation or update of an SI representing storage management software
- Directly discovered storage using WBEM queries to the WBEM/SMI-S provider triggered by the creation or update of a Storage Device node representing the chassis
- Directly discovered storage using SNMP triggered by the creation or update of a Storage Device node representing the chassis
Removal
A Storage Pool node is removed when its parent Storage System node is removed. This is Containment Removal.
