Recomposing a System Disk

Scenarios

If a purchased desktop needs to be restored to the initial template or desktop applications and patches need to be updated, you can recompose or change the system disk.

Impact on the System

If you recompose the system disk, the data (such as the desktop and favorites) on the system disk will be lost. If the data is needed after recomposing, ask the user to back up the data in advance. Recomposing the system disk does not affect data disks.

Restrictions

When recomposing the system disk, if the desktop uses a private image, ensure that the private image still exists.

Prerequisite

The system disk can be recomposed only when the running status of a desktop is running or stopped.

Procedure

Log in to the Workspace console.
In the navigation tree on the left, choose Desktop Management > Desktops.
The desktop management page is displayed.
Select the desktop whose system disk needs to be recomposed and choose More > Rebuild the OS.
The Rebuild the OS page is displayed.

Configure information about the system disk to be rebuilt, as listed in Table 1.
