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.
