Abstract

An FTDC interface with the host or user. The interface can include a command application programming interface (API) or a data storage Command-Line Interface (DS CLI)/Graphical User Interface (GUI). In certain embodiments, the FTDC interface allows a host or user to customize a desired FTDC on a two-tiered system. The first tier is one in which a host/user selects, from a list of conditions, which ones, upon occurrence of those conditions, they would like the controller to perform FTDC. The second tier a second selection such that for each first tier item, the host/user will select the level of FTDC (collection and offloading of logs and/or the forcing and offloading of a statesave).

Claims

1. A computer-implementable method for providing a first time data collection (FTDC) function to a storage controller comprising:

providing an FTDC interface, the FTDC interface allowing a host to interface with the storage controller; and

,

enabling customization of an FTDC operation operating on the storage controller via the FTDC interface.

2. The method of claim 1 wherein:

the FTDC operation comprises a two tiered operation, a first tier of the two tiered operation enabling a user to identify a condition from a list of conditions where detection of the condition causes initiation of an FTDC operation and a second tier of the two tier operation enabling a user to select a level of data collection for the condition so identified.

3. The method of claim 2 wherein:

the condition is selected from a list of conditions comprising binary conditions, threshold conditions and conditional conditions.

4. The method of claim 2 wherein:

the level of data collection comprises at least one of a collect and offload log operation, a collect and offload save state operation and a collect and offload log and save state operation.

5. The method of claim 1 wherein:

the enabling customization of the FTDC operation enables collection of FTDC data for pseudo error conditions based upon at least one of detection of predetermined threshold values or an occurrence of predetermined conditions.

6. The method of claim 5 wherein:

the pseudo error conditions comprise at least one of a selective reset, a system reset, and a Peer-to-Peer Remote Copy suspend of paths or pairs.

7. The method of claim 1 wherein:

the FTDC interface comprises at least one of an application programming interface (API), a data storage Command-Line Interface (DS CLI), and a Graphical User Interface (GUI).

8. A system comprising:

a processor;

a data bus coupled to the processor; and

a computer-usable medium embodying computer program code, the computer-usable medium being coupled to the data bus, the computer program code comprising instructions executable by the processor and configured for;

providing a first time data collection (FTDC) interface, the FTDC interface allowing a host to interface with the storage controller; and

,

enabling customization of an FTDC operation operating on the storage controller via the FTDC interface.

9. The system of claim 8 wherein:

the FTDC operation comprises a two tiered operation, a first tier of the two tiered operation enabling a user to identify a condition from a list of conditions where detection of the condition causes initiation of an FTDC operation and a second tier of the two tier operation enabling a user to select a level of data collection for the condition so identified.

10. The system of claim 9 wherein:

the condition is selected from a list of conditions comprising binary conditions, threshold conditions and conditional conditions.

11. The system of claim 9 wherein:

the level of data collection comprises at least one of a collect and offload log operation, a collect and offload save state operation and a collect and offload log and save state operation.

12. The system of claim 8 wherein:

the enabling customization of the FTDC operation enables collection of FTDC data for pseudo error conditions based upon at least one of detection of predetermined threshold values or an occurrence of predetermined conditions.

13. The system of claim 12 wherein:

the pseudo error conditions comprise at least one of a selective reset, a system reset, and a Peer-to-Peer Remote Copy suspend of paths or pairs.

14. The system of claim 8 wherein:

the FTDC interface comprises at least one of an application programming interface (API), a data storage Command-Line Interface (DS CLI), and a Graphical User Interface (GUI).

15. A computer-usable medium embodying computer program code, the computer program code comprising computer executable instructions configured for:

providing a first time data collection (FTDC) interface, the FTDC interface allowing a host to interface with the storage controller; and

,

enabling customization of an FTDC operation operating on the storage controller via the FTDC interface.

16. The computer-usable medium of claim 15, wherein:

the FTDC operation comprises a two tiered operation, a first tier of the two tiered operation enabling a user to identify a condition from a list of conditions where detection of the condition causes initiation of an FTDC operation and a second tier of the two tier operation enabling a user to select a level of data collection for the condition so identified.

17. The computer-usable medium of claim 16, wherein:

the condition is selected from a list of conditions comprising binary conditions, threshold conditions and conditional conditions.

18. The computer-usable medium of claim 16, wherein:

the level of data collection comprises at least one of a collect and offload log operation, a collect and offload save state operation and a collect and offload log and save state operation.

19. The computer-usable medium of claim 15, wherein:

the enabling customization of the FTDC operation enables collection of FTDC data for pseudo error conditions based upon at least one of detection of predetermined threshold values or an occurrence of predetermined conditions.

20. The computer-usable medium of claim 19, wherein:

the pseudo error conditions comprise at least one of a selective reset, a system reset, and a Peer-to-Peer Remote Copy suspend of paths or pairs.

21. The computer-usable medium of claim 19, wherein:

the FTDC interface comprises at least one of an application programming interface (API), a data storage Command-Line Interface (DS CLI), and a Graphical User Interface (GUI).
