Abstract

In accordance with embodiments of the present disclosure, a system may include a storage controller for managing virtual storage resources and physical storage resources of one or more information handling systems. The storage controller may be configured to, responsive to removal of a physical storage resource owned by the storage controller from a first information handling system broadcast a request to one or more other information handling systems to determine if the physical storage resource has been relocated to a second information handling system. The storage controller may also be configured to, responsive to receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system, operate in concert with a second storage controller of the second information handling system to use the data of the physical storage resource.

Claims (29)

1. A system comprising:

a storage controller for managing virtual storage resources and physical storage resources of one or more information handling systems, the storage controller configured to, responsive to removal of a physical storage resource owned by the storage controller from a first information handling system:

broadcast a request to one or more other information handling systems to determine if the physical storage resource has been relocated to a second information handling system;

responsive to receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system, operate in concert with a second storage controller of the second information handling system to use data of the physical storage resource;

determine a timeout period before beginning a rebuild process for data of the physical storage resource; and

rebuild the virtual storage resource using a second physical storage resource responsive to expiration of the timeout period before receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system.

2. The system of claim 1 , wherein using the data of the physical storage resource comprises the storage controller assuming remote ownership of the physical storage resource and managing the physical storage resource as a member of a virtual storage resource from which the physical storage resource was removed.

3. The system of claim 1 , wherein using the data of the physical storage resource comprises the storage controller cloning data of the physical storage resource to a second physical storage resource owned by the storage controller and managing the second physical storage resource as a member of a virtual storage resource from which the physical storage resource was removed.

4. The system of claim 1 , wherein the storage controller is configured to, responsive to receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system, release the physical storage resource to the second information handling system.

5. The system of claim 1 , wherein the storage controller is configured to, responsive to receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system, communicate configuration information for a virtual storage resource from which the physical storage resource was removed to the second information handling system such that the ownership of the virtual storage resource is transferred to the second information handling system.

6. The system of claim 1 , the storage controller further configured to, responsive to removal of the physical storage resource:

calculate an estimated rebuild time to rebuild a virtual storage resource from which the physical storage resource was removed to a non-degraded state;

determine the estimated rebuild time is greater than a threshold amount of time; and

broadcast the request responsive to a determination that the estimated rebuild time is greater than the threshold amount of time.

7. The system of claim 6 , the storage controller configured to rebuild the virtual storage resource using a second physical storage resource responsive to a determination that the estimated rebuild time is lesser than the threshold amount of time.

8. A method comprising, responsive to removal of a physical storage resource owned by a storage controller from a first information handling system:

broadcasting a request to one or more other information handling systems to determine if the physical storage resource has been relocated to a second information handling system;

responsive to receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system, operating in concert with a second storage controller of the second information handling system to use data of the physical storage resource;

determining a timeout period before beginning a rebuild process for data of the physical storage resource; and

rebuilding a virtual storage resource using a second physical storage resource responsive to expiration of the timeout period before receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system.

9. The method of claim 8 , wherein using the data of the physical storage resource comprises the storage controller assuming remote ownership of the physical storage resource and managing the physical storage resource as a member of a virtual storage resource from which the physical storage resource was removed.

10. The method of claim 8 , wherein using the data of the physical storage resource comprises the storage controller cloning data of the physical storage resource to a second physical storage resource owned by the storage controller and managing the second physical storage resource as a member of a virtual storage resource from which the physical storage resource was removed.

11. The method of claim 8 , further comprising, responsive to receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system, releasing the physical storage resource to the second information handling system.

12. The method of claim 11 , further comprising, responsive to receiving a reply from the second information handling system indicating that the physical storage resource has been relocated to the second information handling system, communicating configuration information for a virtual storage resource from which the physical storage resource was removed to the second information handling system such that the ownership of the virtual storage resource is transferred to the second information handling system.

13. The method of claim 8 , further comprising, responsive to removal of the physical storage resource:

calculating an estimated rebuild time to rebuild a virtual storage resource from which the physical storage resource was removed to a non-degraded state;

determining the estimated rebuild time is greater than a threshold amount of time; and

broadcasting the request responsive to a determination that the estimated rebuild time is greater than the threshold amount of time.

14. The method of claim 13 , further comprising rebuilding the virtual storage resource using a second physical storage resource responsive to a determination that the estimated rebuild time is lesser than the threshold amount of time.
