Abstract

Systems and methods for automatically resuming commissioning of a partition image after a halt in the commissioning process are disclosed. Embodiments may include initiating a commissioning of a partition image. Embodiments may also include updating metadata associated with the commissioning of the partition image after each successfully executed step of the commissioning process. Embodiments may further include identifying a halt in the commissioning process and resuming, after the halt has been identified, the commissioning process from the last successfully executed step of the commissioning process stored in the metadata during the most recent update of the metadata.

Claims

1. A method for automatically resuming commissioning of a partition image after the commissioning process, comprising:

initiating, by a computing system, a commissioning of a partition image, wherein commissioning of the partition image comprises execution, by the computing system, of a sequence of steps specified by a commissioning process;

updating, by the computing system, metadata associated with the commissioning of the partition image after each successfully executed step of the commissioning process;

identifying, by the computing system, a halt in the commissioning process; and

resuming, by the computing system, after the halt has been identified, the commissioning process from the last successfully executed step of the commissioning process stored in the metadata during the most recent update of the metadata,

2. The method of claim 1, wherein resuming the commissioning process comprises resuming the commissioning process without restarting the commissioning process from the beginning of the commissioning process.

3. The method of claim 1, further comprising retrieving the updated metadata from memory after the halt has been identified, wherein resumption of the commissioning process is effectuated based, at least in part, on the updated metadata retrieved.

4. The method of claim 3, further comprising determining if settings of the computing system have changed between the time when the commissioning process was halted and the time when the updated metadata was retrieved.

5. The method of claim 4, further comprising:

restarting the commissioning process from the beginning of the commissioning process when the settings of the computing system have changed and the changes to the settings of the computing system prevent resumption of the commissioning process; and

updating the metadata with the changes to the computing system and resuming the commissioning process from the last successfully executed step of the commissioning process when the settings of the computing system have changed and the changes to the settings of the computing system do not prevent resumption of the commissioning process from the last successfully executed step of the commissioning process.

6. The method of claim 1, wherein the halt comprises at least one of a failure and an interruption.

7. The method of claim 1, wherein the sequence of steps of the commissioning process comprise at least one of acquiring hardware resources of the computing system and installing an operating system image instance.

8. A computer program product, comprising:

a non-transitory computer readable medium comprising instructions which, when executed by a processor of a computer system, cause the processor to perform the steps of;

initiating a commissioning of a partition image, wherein commissioning of the partition image comprises execution, by the computing system, of a sequence of steps specified by a commissioning process;

updating metadata associated with the commissioning of the partition image after each successfully executed step of the commissioning process;

identifying a halt in the commissioning process; and

resuming after the halt has been identified, the commissioning process from the last successfully executed step of the commissioning process stored in the metadata during the most recent update of the metadata.

9. The computer program product of claim 8, wherein resuming the commissioning process comprises resuming the commissioning process without restarting the commissioning process from the beginning of the commissioning process.

10. The computer program product of claim 8, wherein the medium further comprises instructions which cause the processor to perform the step of retrieving the updated metadata from memory after the halt has been identified, wherein resumption of the commissioning process is effectuated based, at least in part, on the updated metadata retrieved.

11. The computer program product of claim 10, Wherein the medium further comprises instructions which cause the processor to perform the step of determining if settings of the computing system have changed between the time when the commissioning process was halted and the time when the updated metadata was retrieved.

12. The computer program product of claim 11, wherein the medium further comprises instructions which cause the user to perform the steps of:

restarting the commissioning process from the beginning of the commissioning process when the settings of the computing system have changed and the changes to the settings of the computing system prevent resumption of the commissioning process; and

updating the metadata with the changes to the computing system and resuming the commissioning process from the last successfully executed step of the commissioning process when the settings of the computing system have changed and the changes to the settings of the computing system do not prevent resumption of the commissioning process from the last successfully executed step of the commissioning process.

13. The computer program product of claim 8, wherein the halt comprises at least one of a failure and an interruption.

14. The computer program product of claim 8, wherein the sequence of steps of the commissioning process comprise at least one of acquiring hardware resources of the computing system and installing an operating system image instance.

15. An apparatus, comprising:

a memory; and

a processor coupled to the memory, wherein the processor is further configured to perform the steps of;

initiating a commissioning of a partition image, wherein commissioning of the partition image comprises execution, by the computing system, of a sequence of steps specified by a commissioning process;

updating metadata associated with the commissioning of the partition image after each successfully executed step of the commissioning process;

identifying a halt in the commissioning process; and

resuming after the halt has been identified, the commissioning process from the last successfully executed step of the commissioning process stored in the metadata during the most recent update of the metadata.

16. The apparatus of claim 15, wherein resuming the commissioning process comprises resuming the commissioning process without restarting the commissioning process from the beginning of the commissioning process.

17. The apparatus of claim 15, wherein the processor is further configured to perform the step of retrieving the updated metadata from memory after the halt has been identified, wherein resumption of the commissioning process is effectuated based, at least in part, on the updated metadata retrieved.

18. The apparatus of claim 17, wherein the processor is further configured to perform the step of determining if settings of the computing system have changed between the time when the commissioning process was halted and the time when the updated metadata was retrieved.

19. The apparatus of claim 18, wherein the processor is further configured to perform the steps of:

restarting the commissioning process from the beginning of the commissioning process when the settings of the computing system have changed and the changes to the settings of the computing system prevent resumption of the commissioning process; and

updating the metadata with the changes to the computing system and resuming the commissioning process from the last successfully executed step of the commissioning process when the settings of the computing system have changed and the changes to the settings of the computing system do not prevent resumption of the commissioning process from the last successfully executed step of the commissioning process.

20. The apparatus of claim 15, wherein the halt comprises at least one of a failure and an interruption, and wherein the sequence of steps of the commissioning process comprise at least one of acquiring hardware resources of the computing system and installing an operating system image instance.
