1. 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.

18. A system for dynamically allocating control of a storage device, the system comprising:
-
a storage device for performing storage operations as directed by a storage controller computer;
a first storage controller computer programmed to direct storage operations performed by the storage device;
a second storage controller computer programmed to direct storage operations performed by the storage device; and
a storage manager computer programmed, based upon an access request from a first computer requesting access to the storage device, to direct a first storage controller computer to assume an inactive state with respect to control of the storage device and to direct a second storage controller computer to assume an active state with respect to control of the storage device. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
