| Region | - | Mandatory The region where the tenant belongs. | - |
| AZ | - | Mandatory The availability zone (AZ) where you want to create the disk. NOTE: - Disks can only be attached to the servers in the same AZ.
- The AZ of a disk cannot be changed after the disk has been created.
| - |
| Disk Specifications | Disk Type | Mandatory Select a storage pool from the drop-down list. The disk type is the same as the storage pool type. | Ultra-high I/O |
| Capacity (GB) | Mandatory The capacity of the disk. The capacity range is from 10 GB to the available capacity displayed on the page. | 100 GB |
Select Data Source - Create from backup
- Create from image
| Optional - If you choose Create from backup, the backup data is used to create the disk.
Click Select Data Source and choose Create from backup. On the displayed page, select the target backup and click OK. NOTE: - A single backup cannot be used for concurrent disk creation operations. For example, if you are creating disk A from a backup, this backup can be used to create another disk only after disk A has been created.
- If a disk is created from a backup of a system disk, the new disk can be used as a data disk only.
- If you choose Create from image, the image data is used to create the disk.
Click Select Data Source and choose Create from image. On the displayed page, select the target image and click OK. NOTE: - The device type of the new disk is the same as that of the image's source disk.
- The encryption attribute of the new disk is the same as that of the image's source disk.

| Automatic Backup | - | CBR lets you back up disks and ECSs and use the backups to restore data. After you set automatic backup, the system will associate the disk with the backup vault and apply the selected policy to the vault to periodically back up the disk. - Do not use: Skip this configuration if CBR is not required. If you still need to set backup protection after a disk is successfully purchased, log in to the CBR console, locate the target vault, and bind the disk to the vault.
- Use existing
- Select an existing cloud backup vault from the drop-down list.
- Select a backup policy from the drop-down list, or log in to the CBR console and configure a desired one.
- Buy new:
- Set the name of the cloud backup vault, which is a character string consisting of 1 to 64 characters, including letters, digits, underscores (_), and hyphens (-), for example, vault-f61e. The default naming rule is vault_xxxx.
- Enter the vault capacity, which is required for backing up the disk. The vault capacity cannot be less than the size of the disk to be backed up. The value ranges from the disk size to 10,485,760 in the unit of GB.
- Select a backup policy from the drop-down list, or log in to the CBR console and configure a desired one.

| More | | Optional - Share:
If you select Share, a shared disk is created. A shared disk can be attached to up to 16 servers. If you do not select Share, a non-shared disk is created, and the disk can be attached to one server only. When you select both SCSI and Share, a shared SCSI disk is created. NOTE: The sharing attribute of a disk cannot be changed after the disk has been created. - SCSI:
If you select SCSI, a SCSI disk is created. Such disks allow the server OS to directly access the underlying storage media and send SCSI commands to the disks. If you do not select SCSI, a VBD disk is created. That said, the disk device type is VBD, the default device type. NOTE: The device type of a disk cannot be changed after the disk has been created. - Encryption:
The encryption function on this console is used for data disk encryption only. System disk encryption relies on images. For details, see the Image Management Service User Guide. To use the disk encryption function, select Encryption. The displayed dialog box contains the following parameters: - Create Agency
An agency is a trust relationship between two tenants or services. A tenant can create an agency to grant resource access rights to another tenant or service. If the KMS access rights are not granted to EVS, the Create Agency dialog box will be displayed. Otherwise, it will not be displayed. Click Yes to grant the KMS access rights to EVS. After the rights have been granted, EVS can obtain KMS keys to encrypt or decrypt disks. After the KMS access rights have been granted, follow-up operations do not require the rights to be granted again. - KMS Key Name
KMS Key Name is displayed only after the KMS access rights have been granted. KMS Key Name is the identifier of the key, and you can use KMS Key Name to specify the KMS key that is to be used for encryption. You can select one of the following keys: Default Key: After the KMS access rights have been granted to EVS, the system automatically creates a Default Key evs/default. Custom keys: Existing or newly created keys. For details, see in the Data Encryption Workshop User Guide. NOTE: - Before you use the disk encryption function, KMS access rights need to be granted to EVS. If you have the right to grant permissions, grant KMS access rights to EVS directly. If you do not have this permission, contact a user with the security administrator permissions to grant the KMS access rights to EVS, then repeat the preceding operations.
- The encryption attribute of a disk cannot be changed after the disk is created.

| Disk Name | - | Mandatory | For example, if you create two disks and set volume for Disk Name, the disk names will be volume-0001 and volume-0002. |
| Quantity | - | Optional The number of disks to be created. The default value is set to 1, which means only one disk will be created. Currently, you can create up to 100 disks at a time. NOTE: - If the disk is created from a backup, batch creation is not possible, and this parameter must be set to 1.
- If the disk is created from a snapshot, batch creation is not possible, and this parameter must be set to 1.
