Abstract

In general, in one aspect, the invention relates to a method for managing updates, the method includes identifying a sub-tree based on a call graph, generating an update sequence for the sub-tree using the call graph, selecting a first component of the sub-tree based on the update sequence, wherein the first component is a hardware resource, applying an update to the first component to obtain a first updated component, selecting, after applying the update to the first component, a second component of the sub-tree based on the update sequence, and performing an update on the second component.

First claim

What is claimed is:

1. A method for managing updates, the method comprising:
identifying a sub-tree based on a call graph;
generating an update sequence for the sub-tree using the call graph;
selecting a first component of the sub-tree based on the update sequence, wherein the first component is a hardware resource;
applying an update to the first component to obtain a first updated component;
selecting, after applying the update to the first component, a second component of the sub-tree based on the update sequence; and
performing an update on the second component.

2. The method of claim 1 , wherein the call graph specifies a hierarchical relationship between the first component and the second component.

3. The method of claim 1 , wherein the hardware resource is a storage device and wherein applying the update to the first component comprises updating firmware on a controller of the storage device.

4. The method of claim 3 , wherein the second component is a software component executing on a computing device operatively connected to the first component.

5. The method of claim 1 , wherein the update sequence specifies an order in which components of the sub-tree are to be updated.

6. The method of claim 1 ,
wherein the second component is associated with a standby component; and
wherein performing the update of the second component comprises:
generating a backup of data volume associated with the standby component;
applying an update to the standby component to obtain an active component;
making a check to determine that a performance and reliability associated with the active component is below a threshold; and
in response to the determination:
initiating updating of the second component, wherein the second component is transitioned to a role of standby.

7. The method of claim 1 , wherein at least a portion of the call graph is derived using a reference architecture.

8. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing updates, the method comprising:
identifying a sub-tree based on a call graph;
generating an update sequence for the sub-tree using the call graph;
selecting a first component of the sub-tree based on the update sequence, wherein the first component is a hardware resource;
applying an update to the first component to obtain a first updated component;
selecting, after applying the update to the first component, a second component of the sub-tree based on the update sequence; and
performing an update on the second component.

9. The non-transitory computer readable medium of claim 8 , wherein the call graph specifies a hierarchical relationship between the first component and the second component.

10. The non-transitory computer readable medium of claim 8 , wherein the hardware resource is a storage device and wherein applying the update to the first component comprises updating firmware on a controller of the storage device.

11. The non-transitory computer readable medium of claim 10 , wherein the second component is a software component executing on a computing device operatively connected to the first component.

12. The non-transitory computer readable medium of claim 8 , wherein the update sequence specifies an order in which components of the sub-tree are to be updated.

13. The non-transitory computer readable medium of claim 8 ,
wherein the second component is associated with a standby component;
wherein performing the update of the second component comprises:
generating a backup of data volume associated with the standby component;
applying an update to the standby component to obtain an active component;
making a check to determine that a performance and reliability associated with the active component is below a threshold; and
in response to the determination, initiating updating of the second component, wherein the second component is transitioned to a role of standby.

14. The non-transitory computer readable medium of claim 8 , wherein at least a portion of the call graph is derived using a reference architecture.

15. A system for managing updates, the system comprising:
a managed system comprising components;
a distributed control manager, comprising a processor and memory, configured to:
identify a sub-tree based on a call graph;
generate an update sequence for the sub-tree using the call graph;
select a first component of the sub-tree based on the update sequence, wherein the first component is a hardware resource, wherein the first component is one of the components;
apply an update to the first component to obtain a first updated component;
select, after applying the update to the first component, a second component of the sub-tree based on the update sequence, wherein the second component is another one of the components; and
perform an update on the second component.

16. The system of claim 15 , wherein the call graph specifies a hierarchical relationship between the first component and the second component.

17. The system of claim 15 , wherein the hardware resource is a storage device and wherein applying the update to the first component comprises updating firmware on a controller of the storage device.

18. The system of claim 17 , wherein the second component is a software component executing on a computing device operatively connected to the first component.

19. The system of claim 15 , wherein the update sequence specifies an order in which components of the sub-tree are to be updated.

20. The system of claim 15 , wherein at least a portion of the call graph is derived using a reference architecture.
