Figure 2 Process overview
- Make preparations: Register an account on the console and obtain permissions required for creating ECSs and EVS disks.
- Create an EVS disk: Configure the disk parameters, including the disk type, capacity, name, and other information by referring to Creating an EVS Disk.
- Attach the data disk: Attach the separately created disk to an ECS by referring to Attaching an EVS Disk.
- Initialize the data disk: After the data disk is attached, log in to the ECS and initialize the disk before using it. For details about how to initialize the disk, see the following sections:
