Abstract

A method, apparatus and computer instructions for handling a failure of a primary adapter in a data processing system. The primary adapter is monitored for the failure by the device driver. A standby adapter handled by the device driver is switched in place of the primary adapter in response to detecting the failure.

Claims

1. A method in a device driver for handling a failure of a primary adapter in a data processing system, the method comprising:

monitoring the primary adapter for the failure; and

responsive to detecting the failure, switching to a standby adapter handled by the device driver.

2. The method of claim 1, wherein the failure is an occurrence of at least one of a network problem and a port problem.

3. The method of claim 1, wherein the primary adapter is on a first port and the standby adapter is on a second port and wherein the switching step comprises:

switching from the first port to the second port to switch to the standby adapter.

4. The method of claim 3, wherein the first port is assigned an active media access control address prior to a switch from the primary adapter to the standby adapter and wherein the switch from the first port to the second port is made by assigning the second port to an active media access control address.

5. The method of claim 3 further comprising:

initiating a soft reset of the first port.

6. The method of claim 1, wherein the primary adapter is a network adapter.

7. The method of claim 1, wherein the primary adapter is a graphics adapter.

8. A data processing system for handling a failure of a primary adapter in a data processing system, the data processing system comprising:

monitoring means for monitoring the primary adapter for the failure; and

switching means for switching to a standby adapter handled by the device driver responsive to detecting the failure.

9. The data processing system of claim 8, wherein the failure is an occurrence of at least one of a network problem and a port problem.

10. The data processing system of claim 8, wherein the primary adapter is on a first port and the standby adapter is on a second port and wherein the switching means comprises:

means for switching from the first port to the second port to switch to the standby adapter.

11. The data processing system of claim 10, wherein the first port is assigned an active media access control address prior to a switch from the primary adapter to the standby adapter and wherein the switch from the first port to the second port is made by assigning the second port to an active media access control address.

12. The data processing system of claim 10 further comprising:

initiating means for initiating a soft reset of the first port.

13. The data processing system of claim 8, wherein the primary adapter is a network adapter.

14. The data processing system of claim 8, wherein the primary adapter is a graphics adapter.

15. A computer program product in a computer readable medium for handling a failure of a primary adapter in a data processing system, the computer program product comprising:

first instructions for monitoring the primary adapter for the failure; and

second instructions for switching to a standby adapter handled by the device driver responsive to detecting the failure.

16. The computer program product of claim 15, wherein the failure is an occurrence of at least one of a network problem and a port problem.

17. The computer program product of claim 15, wherein the primary adapter is on a first port and the standby adapter is on a second port and wherein the second instructions comprise:

sub-instructions for switching from the first port to the second port to switch to the standby adapter.

18. The computer program product of claim 17, wherein the first port is assigned an active media access control address prior to a switch from the primary adapter to the standby adapter and wherein the switch from the first port to the second port is made by assigning the second port to an active media access control address.

19. The computer program product of claim 17 further comprising:

fourth instructions for initiating a soft reset of the first port.

20. The computer program product of claim 15, wherein the primary adapter is a network adapter.

21. The computer program product of claim 15, wherein the primary adapter is a graphics adapter.

22. A server data processing for obtaining cultural context information from a client, the server data processing system comprising:

a bus system;

a communications unit connected to the bus system;

a memory connected to the bus system, wherein the memory includes a set of instructions; and

a processing unit connected to the bus system, wherein the processing unit executes instructions for a device driver to monitor the primary adapter for the failure and, switch to a standby adapter handled by the device driver in response to detecting the failure.
