Abstract

The present disclosure relates to logical unit number (LUN) management methods and apparatuses. One example method includes receiving a management request, where the management request carries an identifier of a first service, determining, from a plurality of logical units (LUNs) in the storage system based on the identifier of the first service, n LUNs corresponding to the first service, and generating a first interface, where the n LUNs corresponding to the first service are displayed on the first interface, and the n LUNs are configured to store data of the first service.

First claim

1 . A logical unit number (LUN) management method, applied to a storage system, wherein the storage system stores, based on a write input/output (IO) sent by an application server, data of a plurality of services run on the application server into a plurality of logical units (LUNs) in the storage system, and the method comprises:
receiving a management request, wherein the management request carries an identifier of a first service; determining, from the plurality of LUNs based on the identifier of the first service, n LUNs corresponding to the first service; and generating a first interface, wherein the n LUNs corresponding to the first service are displayed on the first interface, the n LUNs are configured to store data of the first service, and n is a positive integer.

2 . The method according to claim 1 , wherein the method further comprises:
receiving a confirmation operation of a user on the first interface; and migrating data in the n LUNs based on the confirmation operation; or displaying migrated evaluation information on the first interface.

3 . The method according to claim 1 , wherein the method further comprises:
receiving at least one of a first selection operation or a second selection operation of a user on the first interface, wherein the first selection operation selects at least one LUN from the n LUNs, and the second selection operation selects at least one LUN from LUNs other than the n LUNs.

4 . The method according to claim 3 , wherein the method further comprises:
migrating data in at least one of the at least one LUN selected by the first selection operation or the at least one LUN selected by the second selection operation; or displaying migrated evaluation information on the first interface.

5 . The method according to claim 3 , wherein the method further comprises:
replicating, deleting, or monitoring the n LUNs; or replicating, deleting, or monitoring at least one of the at least one LUN selected by the first selection operation or the at least one LUN selected by the second selection operation.

6 . The method according to claim 1 , wherein determining, from the plurality of LUNs based on the identifier of the first service, the n LUNs corresponding to the first service comprises:
determining, based on characteristic parameters of the plurality of LUNs in the storage system, p LUNs corresponding to the first service, wherein the p LUNs are at least one of the n LUNs, wherein the characteristic parameters comprise at least one of a LUN configuration parameter or a LUN performance parameter.

7 . The method according to claim 6 , wherein determining, based on the characteristic parameters of the plurality of LUNs in the storage system, the p LUNs corresponding to the first service comprises:
inputting the characteristic parameters of the plurality of LUNs into an algorithm model to obtain the p LUNs.

8 . The method according to claim 6 , wherein the LUN configuration parameter comprises at least one of an input/output operations per second (IOPS), a bandwidth, access latency, a size of the IO, or a read IO ratio that is configured by a user for the LUN, and the LUN performance parameter comprises at least one of a historical average IOPS, historical average latency, or a current free space size during running of the LUN.

9 . The method according to claim 1 , wherein determining, from the plurality of LUNs based on the identifier of the first service, the n LUNs corresponding to the first service comprises:
obtaining, based on information recorded in service configuration of the first service, q LUNs corresponding to the first service, wherein the q LUNs are at least one of the n LUNs.

10 . A logical unit number (LUN) management apparatus, comprising:
at least one processor; an interface, wherein the at least one processor receives or sends data through the interface; and at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising: receiving a management request, wherein the management request carries an identifier of a first service; determining, from a plurality of LUNs of a storage system based on the identifier of the first service, n LUNs corresponding to the first service; and generating a first interface, wherein the n LUNs corresponding to the first service are displayed on the first interface, the n LUNs are configured to store data of the first service, and n is a positive integer.

11 . The apparatus according to claim 10 , wherein the operations further comprise:
receiving a confirmation operation of a user on the first interface; and migrating data in the n LUNs based on the confirmation operation; or displaying migrated evaluation information on the first interface.

12 . The apparatus according to claim 10 , wherein the operations further comprise:
receiving at least one of a first selection operation or a second selection operation of a user on the first interface, wherein the first selection operation selects at least one LUN from the n LUNs, and the second selection operation selects at least one LUN from LUNs other than the n LUNs.

13 . The apparatus according to claim 12 , wherein the operations further comprise:
migrating data in at least one of the at least one LUN selected by the first selection operation or the at least one LUN selected by the second selection operation; or displaying migrated evaluation information on the first interface.

14 . The apparatus according to claim 12 , wherein the operations further comprise:
replicating, deleting, or monitoring the n LUNs; or replicating, deleting, or monitoring at least one of the at least one LUN selected by the first selection operation or the at least one LUN selected by the second selection operation.

15 . The apparatus according to claim 10 , wherein determining, from the plurality of LUNs based on the identifier of the first service, the n LUNs corresponding to the first service comprises:
determining, based on characteristic parameters of the plurality of LUNs in the storage system, p LUNs corresponding to the first service, wherein the p LUNs are at least one of the n LUNs, wherein the characteristic parameters comprise at least one of a LUN configuration parameter or a LUN performance parameter.

16 . The apparatus according to claim 15 , wherein determining, based on the characteristic parameters of the plurality of LUNs in the storage system, the p LUNs corresponding to the first service comprises:
inputting the characteristic parameters of the plurality of LUNs into an algorithm model to obtain the p LUNs.

17 . The apparatus according to claim 15 , wherein the LUN configuration parameter comprises at least one of an input/output operations per second (IOPS), a bandwidth, access latency, a size of the IO, or a read IO ratio that is configured by a user for the LUN, and the LUN performance parameter comprises at least one of a historical average IOPS, historical average latency, or a current free space size during running of the LUN.

18 . The apparatus according to claim 10 , wherein determining, from the plurality of LUNs based on the identifier of the first service, the n LUNs corresponding to the first service comprises:
obtaining, based on information recorded in service configuration of the first service, q LUNs corresponding to the first service, wherein the q LUNs are at least one of the n LUNs.
