1. A system for allocating control of storage media, the system comprising:
- storage media;
a first module executing in one or more computer processors wherein the first module is configured to direct storage operations performed by the storage media;
a second module executing in one or more computer processors, wherein the second module is configured to direct storage operations performed by the storage media; and
a third module executing in one or more computer processors, wherein the third module is configured to, based upon a priority of a storage operation, to 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, andwherein the third module is configured to receive path data indicative of 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.

10. A method for allocating control of storage media, the method comprising:
-
providing a first module executing in one or more computer processors configured to direct storage operations performed by storage media; providing a second module executing in one or more computer processors configured to direct storage operations performed by the storage media; directing with a third module executing in one or more computer processors, based upon a priority of a storage operation, 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; and receiving path data indicative of a network path to the storage media. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
