Abstract

Examples disclosed herein relate to storage unit priority based on configuration information. For example, a processor may analyze configuration information associated with the storage units to create a priority order associated with the storage units. The configuration information associated with each storage unit may be standardized for comparison to the configuration information associated with the other storage units. The processor may perform an action related to the storage units according to the priority order.

Claims

1. A storage system, comprising:

a set of storage units;

a processor to;

analyze configuration information associated with the storage units to create a priority order associated with the storage units,

wherein the configuration information associated with each storage unit is standardized for comparison to the configuration information associated with the other storage units; and

perform an action related to the storage units according to the priority order.

2. The storage system of claim 1, wherein the processor further prioritizes the storage units according to groups of storage units.

3. The storage system of claim 2, wherein the grouping comprises at least one of:

a grouping based on application and a grouping based on host exportation.

4. The storage system of claim 1, wherein the configuration information comprises export information and quality of service information.

5. The storage system of claim 4, wherein the processor further analyzes storage unit usage information and further uses the storage unit usage information to create the priority order.

6. A method, comprising:

determining an export priority value to associate with a storage unit based on host export information associated with the storage unit;

determining a quality of service priority value to associate with the storage unit based on quality of service information associated with the storage unit,

wherein determining the quality of service priority value comprises adjusting the value of quality of service parameters associated with the storage unit using quality of service summary information derived from the set of storage units;

determining an aggregated priority value for each storage unit based on its export priority value and the quality of service priority value; and

positioning the storage unit in a priority list based on the summarized priority information.

7. The method of claim 6, wherein the quality of service information associated with the storage unit comprises quality of service information associated with a group of storage units including the storage unit.

8. The method of claim 6, wherein determining the export priority value comprises standardizing the export priority value compared to other storage units.

9. The method of claim 6, wherein the export priority value comprises a first value associated with whether the storage unit is exported and a second value associated with at least one of how many hosts and host adapters the storage unit is exported to.

10. The method of claim 6, wherein positioning the storage unit in the priority list further comprises positioning the storage unit according to the position of storage units in a group including the storage unit.

11. The method of claim 6, further comprising assigning the storage unit a quality of service parameter value associated with at least one of a system default and a system storage unit mean where the quality of service parameter value of the storage unit is not set.

12. A machine-readable non-transitory storage medium comprising instructions executable by a processor to:

standardize configuration information associated with a group of storage units;

determine priority values associated with each a the storage units based on the standardized configuration information; and

create a priority order list based on the relative value of the priority values.

13. The machine-readable non-transitory storage medium of claim 12, further comprising instructions to create the priority order list based on groupings associated with the storage units.

14. The machine-readable non-transitory storage medium of claim 12, wherein the configuration information related to a storage unit comprises at least one of quality of service information, whether the storage unit is exported, and to how many hosts a storage unit is exported to.

15. The machine-readable non-transitory storage medium of claim 12, further comprising instructions to assign configuration information to a storage unit for the purpose of determining the priority where the configuration information of the storage unit is not set.
