Abstract

A method, computer program product, and computing system for receiving a plurality of input/output (IO) commands for a plurality of configuration objects of a storage system. A modification command for a configuration object of the plurality of configuration objects may be received. The configuration object may be suspended in response to receiving the modification command. One or more IO commands directed to the suspended configuration object from the plurality of IO commands may be processed before the configuration object is modified.

First claim

What is claimed is:

1. A computer-implemented method, executed on a computing device, comprising:
receiving, at the computing device, a plurality of input/output (TO) commands for a plurality of configuration objects of a storage system;
receiving a modification command for a configuration object of the plurality of configuration objects;
suspending the configuration object in response to receiving the modification command, wherein suspending the configuration object includes generating a bitmap indicating whether each of the plurality of IO commands are directed to the suspended configuration object; and
processing one or more IO commands directed to the suspended configuration object from the plurality of IO commands before the configuration object is modified.

2. The computer-implemented method of claim 1 , further comprising:
suspending one or more IO commands directed to the suspended configuration object received subsequent to suspending the configuration object.

3. The computer-implemented method of claim 2 , further comprising:
processing one or more IO commands directed to the suspended configuration object received prior to suspending the configuration object based upon, at least in part, the bitmap.

4. The computer-implemented method of claim 3 , further comprising:
modifying the configuration object based on the modification request in response to processing the one or more IO commands directed to the suspended configuration object received prior to suspending the configuration object and suspending the one or more IO commands directed to the suspended configuration object received subsequent to suspending the configuration object based upon, at least in part, the bitmap.

5. The computer-implemented method of claim 4 , further comprising:
releasing the suspension of the configuration object; and
processing the suspended one or more IO commands directed to the configuration object received subsequent to suspending the configuration object.

6. The computer-implemented method of claim 1 , wherein the configuration object includes a storage volume within the storage system.

7. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
receiving a plurality of input/output (TO) commands for a plurality of configuration objects of a storage system;
receiving a modification command for a configuration object of the plurality of configuration objects;
suspending the configuration object in response to receiving the modification command, wherein suspending the configuration object includes generating a bitmap indicating whether each of the plurality of IO commands are directed to the suspended configuration object; and
processing one or more IO commands directed to the suspended configuration object from the plurality of IO commands before the configuration object is modified.

8. The computer program product of claim 7 , wherein the operations further comprise:
suspending one or more TO commands directed to the suspended configuration object received subsequent to suspending the configuration object.

9. The computer program product of claim 8 , wherein the operations further comprise:
processing one or more TO commands directed to the suspended configuration object received prior to suspending the configuration object based upon, at least in part, the bitmap.

10. The computer program product of claim 9 , wherein the operations further comprise:
modifying the configuration object based on the modification request in response to processing the one or more TO commands directed to the suspended configuration object received prior to suspending the configuration object and suspending the one or more TO commands directed to the suspended configuration object received subsequent to suspending the configuration object based upon, at least in part, the bitmap.

11. The computer program product of claim 10 , wherein the operations further comprise:
releasing the suspension of the configuration object; and
processing the suspended one or more TO commands directed to the configuration object received subsequent to suspending the configuration object.

12. The computer program product of claim 7 , wherein the configuration object includes a storage volume within the storage system.

13. A computing system comprising:
a memory architecture; and
a processor configured to receive a plurality of input/output (TO) commands for a plurality of configuration objects of a storage system, wherein the processor is further configured to receive a modification command for a configuration object of the plurality of configuration objects, wherein the processor is further configured to suspend the configuration object in response to receiving the modification command, wherein suspending the configuration object includes: generating a bitmap indicating whether each of the plurality of TO commands are directed to the suspended configuration object, processing one or more TO commands directed to the suspended configuration object received prior to suspending the configuration object based upon, at least in part, the bitmap; suspending one or more TO commands directed to the suspended configuration object received subsequent to suspending the configuration object; and modifying the configuration object based on the modification request in response to processing the one or more TO commands directed to the suspended configuration object received prior to suspending the configuration object and suspending the one or more TO commands directed to the suspended configuration object received subsequent to suspending the configuration object based upon, at least in part, the bitmap, and wherein the processor is further configured to process one or more TO commands directed to the suspended configuration object from the plurality of TO commands before the configuration object is modified.

14. The computing system of claim 13 , wherein the processor is further configured to:
release the suspension of the configuration object; and
process the suspended one or more IO commands directed to the configuration object received subsequent to suspending the configuration object.
