Abstract

A method, system, and computer usable program product for identifying a defective adapter are provided in the illustrative embodiments. A configuration process of the adapter is initiated, the adapter being coupled with a slot in a data processing system. An indication of the configuration process is activated. A determination is made whether the configuration has completed successfully. The indication is allowed to remain activated responsive to the configuration not completing successfully. The activated indication identifies the defective adapter.

Claims

1. A computer implemented method for identifying a defective adapter, comprising:

initiating configuration of the adapter, the adapter being coupled with a slot in a data processing system;

activating an indication of the configuration;

determining whether the configuration has completed successfully; and

allowing the indication to remain activated responsive to the configuration not completing successfully, the activated indication identifying the defective adapter.

2. The computer implemented method of claim 1, wherein the adapter is one of a plurality of adapters, and wherein the configuration is one of a plurality of configurations to be performed on the plurality of adapters, further comprising:

serializing the plurality of configurations such that a second configuration of a second adapter initiates when a first configuration of a first adapter has completed successfully; and

preventing the second configuration from proceeding responsive to the activated indication identifying the defective adapter.

3. The computer implemented method of claim 1, wherein the configuration not completing successfully is a failure, further comprising:

triggering a recovery process to recover the data processing system from the failure.

4. The computer implemented method of claim 1, wherein the adapter is identified as being defective one of (i) when the configuration has not concluded after passage of a predetermined period, and (ii) an event indicating the failure of the configuration is detected.

5. The computer implemented method of claim 1, further comprising:

deactivating the indication responsive to the configuration concluding successfully.

6. The computer implemented method of claim 1, wherein the indication being a state of a notification device associated with the slot, the notification device being one of (i) a visual notification device, (ii) an audio notification device, and (iii) a data bit.

7. The computer implemented method of claim 6, wherein the notification device is an existing device associate with the slot and is repurposed for use as the indication.

8. The computer implemented method of claim 1 wherein the initiating the configuration of the adapter occurs as a result of adding the adapter to the data processing system in a hot-swap process.

9. A computer usable program product comprising a computer usable storage medium including computer usable code for identifying a defective adapter, the computer usable code comprising:

computer usable code for initiating configuration of the adapter, the adapter being coupled with a slot in a data processing system;

computer usable code for activating an indication of the configuration;

computer usable code for determining whether the configuration has completed successfully; and

computer usable code for allowing the indication to remain activated responsive to the configuration not completing successfully, the activated indication identifying the defective adapter.

10. The computer usable program product of claim 9, wherein the adapter is one of a plurality of adapters, and wherein the configuration is one of a plurality of configurations to be performed on the plurality of adapters, further comprising:

computer usable code for serializing the plurality of configurations such that a second configuration of a second adapter initiates when a first configuration of a first adapter has completed successfully; and

computer usable code for preventing the second configuration from proceeding responsive to the activated indication identifying the defective adapter.

11. The computer usable program product of claim 9, wherein the configuration not completing successfully is a failure, further comprising:

computer usable code for triggering a recovery process to recover the data processing system from the failure.

12. The computer usable program product of claim 9, wherein the adapter is identified as being defective one of (i) when the configuration has not concluded after passage of a predetermined period, and (ii) an event indicating the failure of the configuration is detected.

13. The computer usable program product of claim 9, further comprising:

computer usable code for deactivating the indication responsive to the configuration concluding successfully.

14. The computer usable program product of claim 9, wherein the indication being a state of a notification device associated with the slot, the notification device being one of (i) a visual notification device, (ii) an audio notification device, and (iii) a data bit.

15. The computer usable program product of claim 14, wherein the notification device is an existing device associate with the slot and is repurposed for use as the indication.

16. The computer usable program product of claim 9 wherein the initiating the configuration of the adapter occurs as a result of adding the adapter to the data processing system in a hot-swap process.

17. The computer usable program product of claim 9, wherein the computer usable code is stored in a computer readable storage medium in a data processing system, and wherein the computer usable code is transferred over a network from a remote data processing system.

18. The computer usable program product of claim 9, wherein the computer usable code is stored in a computer readable storage medium in a server data processing system, and wherein the computer usable code is downloaded over a network to a remote data processing system for use in a computer readable storage medium associated with the remote data processing system.

19. A data processing system for identifying a defective adapter, the data processing system comprising:

a storage device including a storage medium, wherein the storage device stores computer usable program code; and

a processor, wherein the processor executes the computer usable program code, and wherein the computer usable program code comprises;

computer usable code for initiating configuration of the adapter, the adapter being coupled with a slot in a data processing system;

computer usable code for activating an indication of the configuration;

computer usable code for determining whether the configuration has completed successfully; and

computer usable code for allowing the indication to remain activated responsive to the configuration not completing successfully, the activated indication identifying the defective adapter.

20. The data processing system of claim 19, wherein the adapter is one of a plurality of adapters, and wherein the configuration is one of a plurality of configurations to be performed on the plurality of adapters, further comprising:

computer usable code for serializing the plurality of configurations such that a second configuration of a second adapter initiates when a first configuration of a first adapter has completed successfully; and

computer usable code for preventing the second configuration from proceeding responsive to the activated indication identifying the defective adapter.
