Abstract

A method, non-transitory computer readable medium and computing device that determines in response to an event when currently owned spare data storage devices by one of a pair of storage node computing devices in a high availability pair are insufficient to satisfy a requirement for the event for one or more additional spare data storage devices having one or more data storage device parameters. One or more currently owned spare data storage devices by the other one of the storage node computing devices sufficient to satisfy the requirement are identified. The identified one or more currently owned spare data storage devices owned by the other one of the pair of storage node computing devices that satisfy the requirement are assigned to the one of the pair of storage node computing devices.

First claim

What is claimed is:

1. A method, comprising:
determining, by one of a high availability pair of computing devices, in response to an event detected at a spare data storage device dedicated to the one of the computing devices is insufficient to satisfy a data storage parameter for the event, wherein the detected event comprises a detected failure of the data storage device while the computing devices of the high availability pair remain operational;
identifying, by the one of the computing devices, a spare data storage device dedicated to the other one of the computing devices sufficient to satisfy the data storage parameter; and
assigning, by the one of the computing devices, the identified spare data storage device dedicated to the other one of the computing devices that satisfies the data storage parameter to the one of the computing devices.

2. The method of claim 1 further comprising detecting, by the one of the computing devices, the event.

3. The method of claim 1 further comprising obtaining, by the one of the computing devices, a number and the data storage parameter of the data storage device dedicated to each of the computing devices.

4. The method of claim 1 further comprising:
determining, by the one of the computing devices, when the event has been resolved; and
assigning, by the one of the computing devices, the identified data storage device back to the other one of the computing devices when the event has been determined to be resolved.

5. A non-transitory machine readable medium having stored thereon instructions for performing a method comprising machine executable code which when executed by at least one machine causes the machine to:
determine in response to an event detected at a spare data storage device dedicated to one of a high availability pair of computing devices is insufficient to satisfy a data storage parameter, wherein the detected event comprises a detected failure of the data storage device while the computing devices of the high availability pair remain operational;
identify a spare data storage device dedicated to the other one of the computing devices sufficient to satisfy the data storage parameter; and
assign the identified spare data storage device dedicated to the other one of the computing devices that satisfies the data storage parameter to the one of the computing devices.

6. The medium of claim 5 wherein the instructions for performing the method comprise machine executable code which when executed by at least one machine causes the machine to detect the event.

7. The medium of claim 5 wherein the instructions for performing the method comprise machine executable code which when executed by at least one machine causes the machine to obtain a number of and the data storage parameter of the data storage device dedicated to each of the computing devices.

8. The medium of claim 5 wherein the instructions for performing the method comprise machine executable code which when executed by at least one machine causes the machine to:
determine when the event has been resolved; and
assign the identified data storage device by the one of the computing devices to the other one of the computing devices when the event has been determined to be resolved.

9. A computing device comprising:
a memory containing machine readable medium comprising machine executable code having stored thereon instructions for performing a method; and
a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to:
determine in response to an event detected at a spare data storage device dedicated to one of a high availability pair of computing devices is insufficient to satisfy a data storage parameter, wherein the detected event comprises a detected failure of the data storage device while the computing devices of the high availability pair remain operational;
identify a spare data storage device dedicated to the other one of the computing devices sufficient to satisfy the data storage parameter; and
assign the identified one or more spare data storage device dedicated to the other one of the computing devices that satisfies the data storage parameter to the one of the computing devices.

10. The device of claim 9 wherein the processor is further configured to execute the machine executable code to further cause the processor to: detect the event.

11. The device of claim 9 wherein the processor is further configured to execute the machine executable code to further cause the processor to:
obtain a number of and the data storage parameters of the data storage device dedicated to each of the computing devices.

12. The device of claim 9 wherein the processor is further configured to execute the machine executable code to further cause the processor to:
determine when the event has been resolved; and
assign the identified data storage device by the one of the computing devices to the other one of the computing devices when the event has been determined to be resolved.
