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.
What is claimed is: 1. A method for dynamically allocating control of a storage device, the method comprising: receiving an access request from a client computer requesting access to a storage device; directing, based upon the access request, a first computer to assume an inactive state with respec
What is claimed is: 1. A method for dynamically allocating control of a storage device, the method comprising: receiving an access request from a client computer requesting access to a storage device; directing, based upon the access request, a first computer to assume an inactive state with respect to control of the storage device; directing, based upon the access request, a second computer to assume an active state with respect to control of the storage device; and generating storage path data indicating a network path to the storage device. 2. The method of claim 1, wherein generating storage path data comprises generating storage path data at the second computer. 3. The method of claim 2, comprising communicating the storage path data to a third computer configured to perform said directing the first computer and said directing the second computer. 4. The method of claim 2, comprising communicating the storage path data to the client computer. 5. A method for dynamically allocating control of a storage device, the method comprising: receiving an access request from a client computer requesting access to a storage device; directing, based upon the access request, a first computer to assume an inactive state with respect to control of the storage device; directing, based upon the access request, a second computer to assume an active state with respect to control of the storage device; and allocating control of the storage based on the priority of a storage operation. 6. A method for dynamically allocating control of a storage device, the method comprising: receiving an access request from a client computer requesting access to a storaqe device; directing, based upon the access request, a first computer to assume an inactive state with respect to control of the storage device; directing, based upon the access request, a second computer to assume an active state with respect to control of the storage device; and storing, in a database, control data indicating a change in control of the storage device, wherein storing control data in a database comprises storing control data in a database of at least one of the first and second computers. 7. A method for dynamically allocating control of a storage device, the method comprising: receiving an access request from a client computer requesting access to a storage device; directing, based upon the access request, a first computer to assume an inactive state with respect to control of the storage device; directing, based upon the access request, a second computer to assume an active state with respect to control of the storage device; and storing, in a database, control data indicating a change in control of the storage device, wherein storing control data in a database comprises storing control data in a database of a third computer configured to perform said directing the first computer and said directing the second computer. 8. A method for dynamically allocating control of a storage device, the method comprising: receiving an access request from a client computer requesting access to a storage device; directing, based upon the access request, a first computer to assume an inactive state with respect to control of the storage device; directing, based upon the access request, a second computer to assume an active state with respect to control of the storage device; storing, in a database, control data indicating a chance in control of the storage device; and identifying, based upon the control data, whether the first computer or second computer is available to perform a storage operation. 9. The method of claim 8, comprising directing, based upon the availability of the first computer or second computer, a third computer to assume an active state with respect to control of the storage device. 10. A system for dynamically allocating control of a storage device, the system comprising: a storage device; a first computer configured to direct storage operations performed by the storage device; a second computer configured to direct storage operations performed by the storage device; and a third computer configured, based upon an access request from a client computer requesting access to the storage device, to direct the first computer to assume an inactive state with respect to control of the storage device and to direct the second computer to assume an active state with respect to control of the storage device, wherein the first and second computers are programmed to generate storage path data indicating a network path to the storage device. 11. The system of claim 10, wherein the first and second computers are programmed to communicate the storage path data to the third computer. 12. The system of claim 10, wherein the first and second computers are programmed to communicate the storage path data to the client computer. 13. A system for dynamically allocating control of a storage device, the system comprising: a storage device; a first computer configured to direct storage operations performed by the storage device; a second computer configured to direct storage operations performed by the storage device; and a third computer configured, based upon an access request from a client computer requesting access to the storage device, to direct the first computer to assume an inactive state with respect to control of the storage device and to direct the second computer to assume an active state with respect to control of the storage device, wherein the third computer is programmed to generate storage path data indicating a network path to the storage device. 14. The system of claim 13, wherein the third computer is programmed to communicate the storage path data to the client computer. 15. A system for dynamically allocating control of a storage device, the system comprising: a storage device; a first computer configured to direct storage operations performed by the storage device; a second computer configured to direct storage operations performed by the storage device; and a third computer configured, based upon an access request from a client computer requesting access to the storage device, to direct the first computer to assume an inactive state with respect to control of the storage device and to direct the second computer to assume an active state with respect to control of the storage device, wherein each of the first and second computers is programmed to allocate control of the storage device based on the priority of a storage operation. 16. A system for dynamically allocating control of a storage device, the system comprising: a storage device; a first computer configured to direct storage operations performed by the storage device; a second computer configured to direct storage operations performed by the storage device; a third computer configured, based upon an access request from a client computer requesting access to the storage device, to direct the first computer to assume an inactive state with respect to control of the storage device and to direct the second computer to assume an active state with respect to control of the storage device; and a database for storing control data indicating a change in control of the storage device, wherein the database comprises a database of at least one of the first and second computers. 17. A system for dynamically allocating control of a storage device, the system comprising: a storage device; a first computer configured to direct storage operations performed by the storage device; a second computer configured to direct storage operations performed by the storage device; a third computer configured, based upon an access request from a client computer requesting access to the storage device, to direct the first computer to assume an inactive state with respect to control of the storage device and to direct the second computer to assume an active state with respect to control of the storage device; and a database for storing control data indicating a change in control of the storage device, wherein the database comprises a database of the third computer. 18.
