1. A computerized method for allocating control of a robotic arm in a storage device, the method comprising:
- assigning control of a robotic arm associated with a storage device to a first media management device associated with the storage device;
selecting, in accordance with selection logic, a second media management device associated with the storage device; and
transferring, from the first media management device to the second media management device, control of the robotic arm associated with the storage device.

Abstract
The invention relates generally to controlling access to a storage device. In a three-tier storage system including a storage manager, media management devices and storage devices, access to a storage device containing a robotic arm is dynamically assignable to one or more media management devices in accordance with user preferences, storage policies or other logical bases, such as network efficiency or availability. The invention also provides a computerized method for assigning control of a robotic arm to one or more media management devices.
