Buying and Preparing an EVS Disk for a Windows Server

Scenarios

You can use EVS disks as system disks or data disks. System disks are purchased together with servers, while data disks can be purchased together with servers or separately. If you have purchased data disks separately, you must attach and initialize them before they can be used.

This section describes how a non-shared data disk can be purchased on the EVS console, attached to a Windows server, and initialized on the server.

Operation Process

Preparations

1. Sign up with Huawei Cloud.
   • To sign up for a HUAWEI ID and enable Huawei Cloud services, see Signing Up for a HUAWEI ID and Enabling Huawei Cloud Services.
   • To complete real-name authentication, see Getting Authenticated.
2. Top up your account.
   1. To learn more about EVS pricing, see Billing.
   2. To top up an account, see Topping Up an Account.

Step 1: Purchase an EVS Disk

1. Go to the Buy Disk page.
2. Configure mandatory parameters based on the following table and retain the default settings for other parameters.

   

   Parameter	Example Value	Description
   Attach to Server	Later	You can attach the disk after it is purchased.
   Region	CN South-Guangzhou	Resources in different regions cannot communicate with each other over an internal network. For low network latency and quick resource access, select the nearest region.
   AZ	AZ1	You can only attach EVS disks to servers in the same AZ. After a disk is purchased, its AZ cannot be changed.
   Billing Mode	Pay-per-use	To learn more about EVS pricing, see Billing.
   Data Source	Do not configure it.	If you want to create an empty data disk, do not configure a data source.
   Disk Type	Ultra-high I/O	To learn more about disk types, see Disk Types and Performance.
   Capacity	100 GiB	Set a disk capacity.
   Disk Encryption	Select this option and use the default key.	EVS uses the industry-standard XTS-AES-256 cryptographic algorithm and keys to encrypt EVS disks. The encryption attribute of a disk cannot be changed after the disk is purchased. If this is your first time using encryption, you need to create an agency to authorize EVS to access KMS. If you have the authorization permissions, just complete the authorization as prompted.
   Advanced Settings > Share	Do not select this option.	A non-shared disk can only be attached to one server. The sharing attribute of a disk cannot be changed after the disk is purchased.
   Advanced Settings > SCSI	Select this option.	A SCSI disk allows the server OS to directly access the underlying storage media and send SCSI commands to the disk. The device type of a disk cannot be changed after the disk is purchased.
   Automatic Backup	Do not configure it.	Automatic backup allows you to back up disk data to ensure data security and integrity.
   Disk Name	volume-0001	Enter a disk name.
   Quantity	1	The preset disk quantity is 1. It means that only one disk will be created.

3. Check your configurations on the configuration summary page. If the information is correct, click Submit.
   • If you select Yearly/Monthly for Billing Mode:
     1. On the displayed page, select a desired payment method and confirm the payment. The system displays a message indicating payment processed successfully.
     2. Click Back to Elastic Volume Service to return to the Elastic Volume Service page.
   • If you select Pay-per-use for Billing Mode:

     On the page with message "Task submitted successfully" displayed, click Go to Disk List to return to the Elastic Volume Service page.

4. Click Next.
5. Go back to the disk list page. When the status of the volume-0001 disk changes to In-use, the disk is successfully created.

Step 2: Attach the EVS Disk

EVS disks cannot be used alone. You need to attach them to cloud servers first. In the following example, the volume-0001 disk is attached.

1. In the disk list, find the volume-0001 disk and click Attach in the Operation column.
2. Attach the volume-0001 disk to your desired server. Ensure that the server and disk are in the same AZ.

   

3. Click OK to go back to the disk list page. When the status of the volume-0001 disk changes to In-use, the disk is successfully attached.

Step 3: Initialize the EVS Disk

After attaching the volume-0001 disk, you need to initialize it before it can be used. In the following example, the disk is formatted into a 100 GiB GPT partition with the NTFS file system.

1. Log in to the server as user root.

   For how to log in to an ECS, see How Do I Log In to My ECS?

   For how to log in to a BMS, see Logging In to a BMS.

2. On the server desktop, right-click and choose Disk Management from the shortcut menu.

   Disks are displayed in the right pane. If there is a disk that is not initialized, the system will prompt you with the Initialize Disk dialog box.

   In the Initialize Disk dialog box, the to-be-initialized disk is selected. Select a partition style and click OK. In this example, GPT (GUID Partition Table) is selected.

   

   The maximum disk size supported by MBR is 2 TiB, and that supported by GPT is 18 EiB. Because an EVS data disk currently supports up to 32 TiB, use GPT if your disk size is greater than 2 TiB.

   If the partition style of an in-use disk is changed, all data on the disk will be lost, so take care to select an appropriate partition style when initializing the disk. If you must change the partition style to GPT, it is recommended that you back up the disk data before the change.

3. In the Unallocated area of Disk 1, right-click the blank area and choose New Simple Volume.

   The New Simple Volume Wizard window is displayed.

4. Click Next to go to the Specify Volume Size page.
   Figure 4 Specify Volume Size
   

5. Specify the volume size and click Next. The system selects the maximum volume size by default. You can specify the volume size as required. In this example, the default setting is used.

6. Assign a drive letter or path to your partition and click Next. The system assigns drive letter D by default. In this example, the default setting is used.

7. Specify format settings and click Next. The system selects the NTFS file system by default. You can specify a file system format as required. In this example, the default setting is used.

   The partition sizes supported by file systems vary. Choose an appropriate file system format based on your service requirements.

8. Click Finish.
   Wait for the initialization to complete. When the volume status changes to Healthy, the initialization has succeeded.

9. After the volume is created, click on the task bar and check whether a new volume appears in the File Explorer. In this example, New Volume (D:) is the new volume.
   If New Volume (D:) appears, the disk is successfully initialized and no further action is required.

You can use the disk after it is initialized.
