Storage Volume Mirror node

A Storage Volume Mirror node represents a mirror image of a Storage Volume, used for high availability.

Creation/update

A Storage Volume Mirror 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 Storage Volume Mirror node is removed when its parent Storage System node is removed. This is Containment Removal.
