Adding a Disk to an ECS

Scenarios

The disks attached to an ECS include one system disk and one or more data disks. The system disk is automatically created and attached when the ECS is created. You do not need to purchase it again. The data disks can be added in either of the following ways:

• During the ECS purchase. Data disks added in this way are automatically attached to the ECS.
• After the ECS is purchased. Data disks added in this way must be manually attached to the ECS.

This section describes how to add a data disk after an ECS is purchased.

Procedure

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

   The page for buying disks is displayed.

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

   For instructions about how to set EVS disk parameters, see Purchasing 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 purchased, it is attached to the ECS by default.
6. Click Next to confirm the order and click Submit to 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.
