11.1 Overview

The parent object in the Media Manager’s object hierarchy is the adapter object. For every non-removable device (that is, a device that can contain only one piece of media, such as a hard disk) the Media Manager automatically creates a media object. The figure below shows an example of how, by starting from the two media objects (one of which is not shown), the Partition API set is used to build a single mirror object. The file system will then perform I/O to the mirror object. Following is a sample sequence of events that properly use the Partition APIs.
