1. A system for allocating control of storage media, the system comprising:
- storage media;
a first module configured to direct storage operations performed by the storage media;
a second module configured to direct storage operations performed by the storage media; and
a third module configured to, based upon a request from a client component for access to the storage media, direct the first module to assume an inactive state with respect to control of the storage media and to direct the second module to assume an active state with respect to control of the storage media,wherein at least one of the first and second modules is configured to generate path data indicating a network path to the storage media.

Abstract
A method for dynamically allocating control of a storage device, the method comprising receiving an access request from a first computer requesting access to a storage device; directing, based upon the access request, a first storage controller computer to assume an inactive state with respect to control of the storage device; and directing, based upon the access request, a second storage controller computer to assume an active state with respect to control of the storage device.

11. A system for allocating control of a storage device, the system comprising:
-
means for storing data; first means for controlling storage operations performed by said storing means, said first controlling means further configured to receive a request from a client component for access to said storing means; second means for controlling storage operations performed by said storing means; and means for directing said second controlling means to assume an inactive state with respect to control of said storing means and for directing said first controlling means to assume an active state with respect to control of said storing means, wherein said first controlling means is further configured to generate path data indicating a network path to said storing means. - View Dependent Claims (12, 13)
