Scenario
This topic uses Windows Server 2012 Standard 64-bit Chinese Edition as an example to describe how to initialise an EVS on Windows with a capacity greater than 2 TB. When the capacity is greater than 2 TB, you must use a GPT partition for disk partitioning.
The formatting operation may differ depending on the operating system of a cloud server. This topic is for reference only.
Before You Begin
The data disk has been attached to a cloud server and has not been initialised.
Operation Steps
If the capacity of the new EVS is less than 2 TB, initialise the Windows-based data disk in two steps as follows:
Log in to the ECS
Initialise the disk: Initialise the disk as instructed on the screen. If the capacity of the new EVS is greater than 2 TB, select GPT (GUID Partition Table) as the partition form.
Log in to the ECS
1. Log in to the console.
2. Click 
in the upper left corner of the console and select a Region. In this topic, China (Hong Kong 2) is selected.
3. Select Compute and click ECS to go to the ECS list page.
Locate the row that contains the cloud server for which the data disk is to be initialised, and in the Operation column, click Remote Login to log in to the cloud server. For more information, see Overview of Windows ECS Login.
Initialising Disk (GPT Partition)
1. After successful login, click the Start icon and select Server Manager in the pop-up menu. You will be directed to the Server Manager > Dashboard window.
2. On this page, click Tools in the upper right corner and select Computer Management from the drop-down menu bar.
3. In the left-side navigation pane on the Computer Management page, select Storage > Disk Management to go to the Disk Management page.
In the disk area, there are two disks: disk 0 and disk 1. Disk 1 has a capacity of 3000 GB, greater than 2 TB and is in offline state. You can right-click and choose Online from the menu list to make the disk go online. Then, the disk status changes from Offline to Not Initialised.
4. Right-click the disk 1 area and choose Initialise Disk from the shortcut menu to initialise the disk.
5. The Initialise Disk dialog box displays an attached disk that you want to initialise, that is, disk 1. Select GPT (GUID Partition Table) and click OK, as shown in the figure.
6. Right-click the unallocated capacity area of disk 1 and choose New Simple Volume, as shown in the following figure.
7. In the New Simple Volume Wizard window that appears, click Next as instructed on the screen.
8. You can specify the volume size as required (we recommend that you calculate the capacity of the disk partition before initialization). The default value is the maximum value. Click Next.
9. On the Assign Drive Letter or Path page, check Assign the following drive letter. The default value is E. Then, click Next.
10. In the Format Partition window, check Format this volume with the following settings, set parameters as required, format the new partition. Here, use the defaults. Then, click Next to go to the Finish page.
11. Click Finish and wait for the system to finish the initialization". If the volume status changes to Healthy, the disk is successfully initialised.
12. To verify the initialization, you can return to the desktop. Click the File Manager icon in the taskbar below to open the file manager to check whether the Volume E is created successfully, as shown in the figure. When the Volume E exists, the disk is initialised.
