It should be noted that the method of creating a logical volume group in the present invention is a virtual grouping method, and the virtual grouping method is to record information for the convenience of managing logical volumes, and there is no real entity in the storage system. Specifically, the virtual grouping manner may be recorded or displayed on a management interface of the storage system.

In practical applications, the user may input a service identifier for creating a logical volume group on a management interface of the storage system, so that the system creates a corresponding logical volume group based on the service identifier.

Step 102: Divide logical volumes associated with the same service into logical volume groups corresponding to the service identifier used to characterize the same service.

Logical volumes associated with the same service are divided into the same logical volume group. Specifically, logical volumes with the same business attribute can be divided into the same logical volume group. For a logical volume group, the service represented by its corresponding service identifier is the same service as the service associated with the logical volumes classified into the logical volume group.

When the user needs to create a logical volume, it can be created based on the determined logical volume group. Optionally, as an implementation of step 102, the logical volume associated with the same service is divided into the same In the logical volume group corresponding to the business ID of the business, it includes:

Specifically, the first logical volume with the service attribute of the first service can be determined based on the attribute information of the logical volume in the storage pool, and divided into the corresponding to the first service identifier. within the logical volume group.

It should be noted that in the present invention, the first service, the first service identifier corresponding to the first service, the first logical volume, the second logical volume, the third logical volume, etc. mentioned later are only for convenience The simple naming for distinction does not specifically refer to a certain business or a certain logical volume.

It should be noted that the above two implementation manners may be implemented in parallel, or implemented separately, that is, they may be in an "and/or" relationship.

Figure 2 shows a schematic diagram of a specific grouping structure. As shown in Figure 2, logical volume group 1, logical volume group 2, ... logical volume group N are created in the storage pool, and logical volume group 1 has logical volume 1 , Logical Volume 2, and Logical Volume 3; Logical Volume Group 2 has Logical Volume 4 and Logical Volume 5; Logical Volume Group 3 has Logical Volume 6 and Logical Volume 7.

Improved search efficiency.

Another embodiment of the present invention discloses a logical volume processing method, as shown in Figure 3, the method includes the following steps:

Step 301: Create logical volume groups corresponding to different service identifiers;

In practical applications, the storage system can provide a quick creation menu on the management interface, and the user can input creation information on the quick creation menu, such as inputting the number and capacity of logical volumes to be created, so as to realize rapid batch creation of logical volumes. Of course, the user can also select the logical volume group to which the second logical volume to be created belongs on the quick creation menu, or directly input creation information under a certain logical volume group, so that the system can determine the logical volume group to which the second logical volume belongs.

In the embodiment of the present invention, by creating logical volume groups corresponding to different service identifiers, the logical volumes associated with the same service are divided into logical volume groups corresponding to the service identifiers used to represent the same service, which can be based on the The business identifier representing the business divides the logical volume, that is, establishes the correlation between the logical volume and the actual business, so that the business associated with the logical volume can be intuitively reflected, and the logical volume belonging to the same business can be viewed based on the logical volume group.

Step 503: When receiving a predetermined operation for the first logical volume, create a third logical volume with the same attribute information as the first logical volume in the logical volume group to which the first logical volume belongs;

The predetermined operation is an operation that triggers the system to create a third logical volume that has the same attribute information as the first logical volume. Optionally, the predetermined operation may include multi-step operations, such as including a copy operation for the first logical volume, and A pasting operation of the logical volume group to which the first logical volume belongs; or, the predetermined operation may be only one-step operation, for example, a certain predetermined operation is directly performed on the first logical volume.

The third logical volume belongs to the same logical volume group as the first logical volume targeted by the predetermined operation, and has the same attribute information.

Step 504: Map the third logical volume to the host of the first logical volume.
