Disk Drive node
A Disk Drive node represents a physical disk drive in a storage system.
A Disk Drive node is created or updated when a storage entity is discovered by one of the following:
- 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
A Disk Drive node is removed when its parent Storage System node is removed. This is Containment Removal.
