Use the Create LDEV function of
Virtual LUN to create a custom-size volume (CV).
The following diagram shows how custom-size volumes (CVs) are created. First you delete fixed-size volumes (FVs) to create free space, and then you can create one or more CVs of any size in that free space.
Configuring custom-sized provisioning involves creating and configuring custom-size volumes (CVs). CVs are created by dividing a fixed-sized volume (FV) into several smaller volumes of arbitrary sizes.
Use this procedure to create one or more internal or external logical volumes (LDEVs) in a selected storage system. You can create multiple LDEVs at once, for example, when you are setting up your storage system. After the storage system is set up, you can add LDEVs as needed.
