Abstract

Claims (51)

1. A method, comprising:

for receipt of an addition or modification of a storage device:

executing a validation process from one or more managed validation kits according to a remote copy function associated with the storage device, the one or more managed validation kits selected according to one or more feature types associated with the remote copy function;

associating the storage device with a corresponding group of storage devices associated with the remote copy function based on information provided by the one or more managed validation kits; and

for the association of the storage device with the corresponding group of storage devices and the execution of the validation process being successful, registering the storage device to a storage class associated with the remote copy function.

2. The method of claim 1 , further comprising executing an automatic health check of the one or more validation kits, the executing comprising:

creating data relations between the one or more validation kits and a control storage device configured to receive dummy data relations;

for the creating of the data relations between the one or more validation kits and the control storage device being successful, returning a healthy status for the health check.

3. The method of claim 1 , further comprising returning a status for each of the one or more validation kits based on referencing a status decision table configured to output the status based on a first result of a health check of the one or more validation kits with a control storage device and a second result of the association of the storage device with the corresponding group of storage devices.

4. The method of claim 1 , further comprising, for the association of the storage device with the corresponding group of storage devices and the execution of the validation process returning a status of temporary failure, automatically re-executing the validation process and reassociating the storage device with the corresponding group after a period of time.

5. The method of claim 1 , further comprising, for a usage of the corresponding group of storage devices associated with the remote copy function exceeding a threshold:

registering the associated storage device to the group of storage devices; and

making the associated storage device available for the remote copy function.

6. The method of claim 1 , further comprising, for the validation process being directed to replication:

creating a path between the storage device to another storage device; and

creating a volume pair between the storage device and the another storage device;

and monitoring a status of the volume pair.

7. A non-transitory computer readable medium, storing instructions for executing a process, the instructions comprising:

for receipt of an addition or modification of a storage device:

executing a validation process from one or more managed validation kits according to a remote copy function associated with the storage device, the one or more managed validation kits selected according to one or more feature types associated with the remote copy function;

associating the storage device with a corresponding group of storage devices associated with the remote copy function based on information provided by the one or more managed validation kits; and

for the association of the storage device with the corresponding group of storage devices and the execution of the validation process being successful, registering the storage device to a storage class associated with the remote copy function.

8. The non-transitory computer readable medium of claim 7 , the instructions further comprising executing an automatic health check of the one or more validation kits, the executing comprising:

creating data relations between the one or more validation kits and a control storage device configured to receive dummy data relations;

for the creating of the data relations between the one or more validation kits and the control storage device being successful, returning a healthy status for the health check.

9. The non-transitory computer readable medium of claim 7 , the instructions further comprising returning a status for each of the one or more validation kits based on referencing a status decision table configured to output the status based on a first result of a health check of the one or more validation kits with a control storage device and a second result of the association of the storage device with the corresponding group of storage devices.

10. The non-transitory computer readable medium of claim 7 , the instructions further comprising, for the association of the storage device with the corresponding group of storage devices and the execution of the validation process returning a status of temporary failure, automatically re-executing the validation process and reassociating the storage device with the corresponding group after a period of time.

11. The non-transitory computer readable medium of claim 7 , the instructions further comprising, for a usage of the corresponding group of storage devices associated with the remote copy function exceeding a threshold:

registering the associated storage device to the group of storage devices; and

making the associated storage device available for the remote copy function.

12. The non-transitory computer readable medium of claim 7 , the instructions further comprising, for the validation process being directed to replication:

creating a path between the storage device to another storage device; and

creating a volume pair between the storage device and the another storage device;

and monitoring a status of the volume pair.

13. An apparatus, comprising:

a processor, configured to, for receipt of an addition or modification of a storage device:

executing a validation process from one or more managed validation kits according to a remote copy function associated with the storage device, the one or more managed validation kits selected according to one or more feature types associated with the remote copy function;

associating the storage device with a corresponding group of storage devices associated with the remote copy function based on information provided by the one or more managed validation kits; and

for the association of the storage device with the corresponding group of storage devices and the execution of the validation process being successful, registering the storage device to a storage class associated with the remote copy function.

14. The apparatus of claim 13 , wherein the processor is further configured to execute an automatic health check of the one or more validation kits, by:

creating data relations between the one or more validation kits and a control storage device configured to receive dummy data relations;

for the creating of the data relations between the one or more validation kits and the control storage device being successful, returning a healthy status for the health check.

15. The apparatus of claim 13 , wherein the processor is further configured to return a status for each of the one or more validation kits based on referencing a status decision table configured to output the status based on a first result of a health check of the one or more validation kits with a control storage device and a second result of the association of the storage device with the corresponding group of storage devices.

16. The apparatus of claim 13 , wherein the processor is further configured to, for the association of the storage device with the corresponding group of storage devices and the execution of the validation process returning a status of temporary failure, automatically re-execute the validation process and reassociating the storage device with the corresponding group after a period of time.

17. The apparatus of claim 13 , wherein the processor is further configured to, for a usage of the corresponding group of storage devices associated with the remote copy function exceeding a threshold:

register the associated storage device to the group of storage devices; and

making the associated storage device available for the remote copy function.

18. The apparatus of claim 13 , wherein the processor is further configured to, for the validation process being directed to replication:

create a path between the storage device to another storage device; and

create a volume pair between the storage device and the another storage device;

and monitor a status of the volume pair.
