Rebuilding a System Disk

Scenarios

If a purchased desktop pool needs to be restored to the initial template or desktop pool applications and patches need to be updated in batches, the administrator can rebuild or change the system disk.

Impact on the System

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

Constraints

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

Prerequisites

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

Procedure

  1. Log in to the console.
  2. In the navigation pane, choose Desktops > Desktop Pools.

    The Desktop Pools page is displayed.

  3. You can access the page for rebuilding the system disk of a desktop pool in either of the following ways:

    Method 1:

    Locate the row that contains the desktop pool whose system disk is to be rebuilt, click More in the Operation column, and select rebuild the OS.

    The dialog box of rebuilding a system disk is displayed.

    Method 2:

    On the desktop pool page, click the name of the desktop pool whose system disk is to be rebuilt. The basic information page of the desktop pool is displayed.

    Click Rebuild the system disk on the right of the Image column in the desktop pool information. The dialog box of rebuilding a system disk is displayed.
