Abstract

The present invention is a system and method for providing clarity and simplicity to the task of screening for errors occurring in a data storage system and improving the effectiveness of the response to these errors. The system and method includes and employs a graphical user interface (GUI) for providing clarity and simplicity. Also by constraining entry texts into a controlled entry field, the likelihood of text-entry errors are greatly reduced. Further by providing menu options, simplicity and clarity are improved while likelihood of text-entry errors are also further reduced. Text-entry error checking tools are also provided to further decrease the probability that such errors will occur. The system and method employ a mechanism to allow for remote error screening and responding to the error from a remote location also.

Claims

1. In a data storage system having a plurality of storage devices and that is in communication with an error response station remotely located from the data storage system, a method for handling at least one error related to the data storage system, the method comprising the steps of:

receiving at an error response station a message about an error related to the data storage system; and

providing a graphical user interface (GUI) useful for entering error handling information in response to receiving the message, wherein information on the GUI presented on the error response station includes information residing on a service processor that has memory and is located proximate to the data storage system and is in communication with the data storage system, such that when the error handling information is indicated as being saved on the GUI it is saved in the memory of the service processor.

2. The method of claim 1, wherein the error handling information includes information regarding an acceptable error quantification threshold for a particular error identified by an error code wherein the threshold is a determining factor regarding whether the particular error may be excluded from a process of calling the error response station to report the particular error.

3. The method of claim 2, wherein the error handling information includes information regarding a device adapter for which the error handling information is related.

4. The method of claim 3, wherein the acceptable quantification threshold is related to the device adapter for which the error handling information is related.

5. The method of claim 2, wherein the acceptable quantification threshold specifies an acceptable amount of error occurrence over a specified period of time.

6. The method of claim 1, wherein the error handling information includes information regarding a device adapter for which the error handling information is related.

7. The method of claim 1, wherein the service processor and the data storage devices are separated by a distance of less than 10 meters.

8. The method of claim 7, wherein the error response station and the data storage devices are separated by a distance of at least 1 kilometer.

9. The method of claim 1, wherein the data storage devices include at least one disk drive and further including the step of spinning down the at least one disk drive and disabling an ability to send error messages related to the at least one disk drive to the error response station.

10. The method of claim 1, wherein the GUI contains at least one entry into which error handling information must be entered to require a predetermined format for such information.

11. The method of claim 10, wherein the GUI includes menu options for inputting data related to the error handling information.

12. The method of claim 10, wherein the GUI is supported by logic that checks for text entry errors in accordance with predetermined conventions.

13. A computer system comprising:

a data storage system including a plurality of storage devices in communication with a service processor that has memory and is located proximate to the data storage system;

an error response station that is located remote to the data storage system and that is in communication with the service processor; and

computer-executable logic that enables;

receiving at the error response station a message about an error related to the data storage system; and

providing a graphical user interface (GUI) useful for entering error handling information in response to receiving the message wherein information on the GUI presented on the error response station includes information residing on the service processor, such that when the error handling information is indicated as being saved on the GUI it is saved in the memory of the service processor.

14. The computer system of claim 13, wherein the error handling information includes information regarding an acceptable error quantification threshold for a particular error identified by an error code wherein the threshold is a determining factor regarding whether the particular error may be excluded from a process of calling the error response station to report the particular error.

15. The computer system of claim 14, wherein the error handling information includes information regarding a device adapter for which the error handling information is related.

16. The computer system of claim 15, wherein the acceptable quantification threshold is related to the device adapter for which the error handling information is related.

17. The computer system of claim 13, wherein the error handling information includes information regarding a device adapter for which the error handling information is related.

18. The computer system of claim 13, wherein the acceptable quantification threshold specifies an acceptable amount of error occurrence over a specified period of time.

19. The computer system of claim 13, wherein the service processor and the data storage devices are separated by a distance of less than 10 meters.

20. The computer system of claim 19, wherein the error response station and the data storage devices are separated by a distance of at least 1 kilometer.

21. The computer system of claim 13, wherein the data storage devices include at least one disk drive and further including the step of spinning down the at least one disk drive and disabling an ability to send error messages related to the at least one disk drive to the error response station.

22. The computer system of claim 13, wherein the GUI contains a least one entry into which data related the error handling information must be entered thereby constraining entry text related to the error to follow a predetermined format.

23. The computer system of claim 22, wherein the GUI includes menu options for inputting data related to the error handling information.

24. The computer system of claim 22, wherein the GUI is supported by logic which checks for text entry errors in accordance with predetermined conventions.

25. A computer program product for use with a data storage system having a plurality of storage devices and which is in communication with an error response station, the computer program product being for management of error handling occurring within the data storage system, the computer program product comprising:

computer-executable logic contained on a computer-readable medium and which is configured for causing the following computer-executed steps to occur;

receiving at an error response station a message about an error related to the data storage system; and

providing a graphical user interface (GUI) useful for entering error handling information in response to receiving the message wherein information on the GUI presented on the error response station includes information residing on the service processor, such that when the error handling information is indicated as being saved on the GUI it is saved in the memory of the service processor.
