Adding a Disk to an ECS

Scenarios

The disks attached to an ECS are classified as system disk and data disk. The system disk of an ECS is automatically created and attached when the ECS is created. You do not need to purchase it separately.

If you add a data disk when purchasing an ECS, the system automatically attaches the data disk to the ECS. You can also separately add data disks after purchasing an ECS, and the disks will be automatically attached to the ECS then.

This section describes how to add a data disk.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. Under Computing, click Elastic Cloud Server.
  4. Locate the row containing the target ECS. Click More in the Operation column and select Manage Image/Disk > Add Disk.

    The page for adding a disk is displayed.

  5. Set parameters for the new EVS disk as prompted.

    For instructions about how to set EVS disk parameters, see Purchase an EVS Disk.

    • By default, the billing mode of the new disk is the same as that of the ECS.
    • By default, the new disk is in the same region as the ECS.
    • By default, the new disk is in the same AZ as the ECS, and the AZ of the disk cannot be changed.
    • After the new disk is created, it is attached to the ECS by default.
    • The expiration time of a new disk billed on a yearly/monthly basis is the same as that of the ECS.
  6. Click Next to confirm the order and complete the payment.

    The system automatically switches back to the Disks tab on the ECS management console. Then, you can view the information of the new disk.

Follow-up Procedure

The system automatically attaches the new disk to the ECS, but the disk can be used only after it is initialized. To do so, log in to the ECS and initialize the disk.

For instructions about how to initialize a data disk, see Introduction to Data Disk Initialization Scenarios and Partition Styles.
