Performing Post-Expansion Operations for a Windows Disk

Scenarios

After expanding the disk capacity on the management console, you need to log in to the Windows server to allocate the additional space to an existing volume or a new volume.

The method for allocating the additional space varies depending on the server OS. This document is used for reference only. For the detailed operations and differences, see the corresponding OS documents.

Performing the expansion operations with caution. Misoperation may lead to data loss or exceptions. Therefore, you are advised to use CBR to back up the disk data before expansion. For details, see Managing a Backup.

Prerequisites

• You have logged in to a server.
  • For how to log in to an ECS, see the Elastic Cloud Server User Guide.
  • For how to log in to a BMS, see the Bare Metal Server User Guide.
• You have attached the disk to the server, and the additional space has not been allocated.

System Disk: Add Additional Space to Volume (C:)

In this example, the system disk has 50 GB originally, and 22 GB is added on the management console. The following procedure describes how to add this 22 GB to volume (C:) on the server. After the operation is complete, volume (C:) will have 72 GB of capacity and can be used as a system volume.

1. On the desktop of the server, right-click Computer and choose Manage from the shortcut menu.

   The Server Manager window is displayed.

2. In the navigation tree, choose Storage > Disk Management.

   The Disk Management window is displayed.

Data Disk: Add Additional Space to Volume (D:)

In this example, the data disk has 100 GB originally, and 50 GB is added on the management console. The following procedure describes how to add this 50 GB to volume (D:) on the server. After the operation is complete, volume (D:) has 150 GB of capacity and can be used as a data volume.

1. On the desktop of the server, right-click Computer and choose Manage from the shortcut menu.

   The Server Manager window is displayed.

2. In the navigation tree, choose Storage > Disk Management.
   The Disk Management window is displayed.
