Installing or upgrading Double-Take Availability for VMware Infrastructure

Double-Take Availability for VMware Infrastructure is a client/server application. You can install the Double-Take Availability for VMware Infrastructure service on one server, then access the service from one or more client machines. The Double-Take Availability for VMware Infrastructure service may be installed on the VMware VirtualCenter server; however, installing both applications on the same server is not mandatory.

The Double-Take Availability for VMware Infrastructure service should be installed on a production server that is highly available. You may optionally install the Double-Take Availability for VMware Infrastructure service on multiple servers; however, if you install multiple instances of the Double-Take Availability for VMware Infrastructure service, it is recommended that each instance manage its own set of ESX servers. No “agent” software is required on the VMware ESX server, nor within any protected virtual machine.

Each Double-Take Availability for VMware Infrastructure service can be managed by multiple clients that are installed on different administrative servers.

The single instance of the Double-Take Availability for VMware Infrastructure service keeps track of your licenses. For information about how to determine the number of virtual machines that you can protect based upon your licenses, see Connecting to the DTAVI server.

Use these instructions to install Double-Take Availability for VMware Infrastructure or upgrade an existing installation.

1. Close any open applications.
2. Start the installation program using the appropriate instructions, depending on your media source.

• CD—Load the Double-Take Availability CD into the local CD-ROM drive. If auto-run is enabled, the installation program will start automatically. To manually start the program, select Start, Run and specify <cd_drive>:\autorun.exe.
• Web download—Launch the .exe file that you downloaded from the web.

3. When the installation program begins, the Double-Take Software Setup Launcher appears allowing you to install software and view documentation for various applications from Double-Take Software. The listed applications will depend on which products are included on the CD or in the web download. To install Double-Take Availability for VMware Infrastructure, select Double-Take Availability from the list of products and then select Install Double-Take Availability for VMware Infrastructure .
4. Depending on your version of Windows and the components you have installed, you may see an initial screen indicating that you should install Microsoft .NET Framework. If you do not see this screen, your server already has the appropriate version of Microsoft .NET. The best practice is to install Microsoft .NET before installing Double-Take Availability for VMware Infrastructure. Clicking Install will continue the installation program and give you the opportunity to install or skip the Microsoft .NET installation. Clicking Cancel will exit the installation program.

Note:

The Microsoft .NET installation in the Double-Take Availability for VMware Infrastructure installation is via a web download. If your server does not have an Internet connection, you must manually install Microsoft .NET from the Double-Take Availability CD or from a copy from the Microsoft web site.

5. When the Double-Take Availability for VMware Infrastructure installation begins, you will be given the opportunity to check for a more recent version of the software.

• If you do not want to check for a later version, select No and click Next.
• If you want to check for a later version, select Yes and click Next. The installation program will establish an Internet connection from your server to the Double-Take Software web site.
• If later versions are found, they will be listed. Highlight the version you want and either download that version and install it automatically or download that version and exit the installation. (If you exit the installation, you can run the updated installation later directly from the location where you saved it.)
• If no later versions are found, continue with the current installation.
• If an Internet connection cannot be established, continue with the current installation or install a previously downloaded version.

6. Review and accept the Double-Take Software license agreement to continue with the installation program. Click Next to continue.
7. If desired, specify where the Double-Take Availability for VMware Infrastructure files will be installed. Click Next to continue.

8. Select the type of installation you would like to perform on this machine.

• Client and Server—This option installs both the client and server components. The server components are required for systems that will function as a source or target. The server requires an activation code for the service to run. The client does not require an activation code, but it is required to administer this and other servers throughout the organization.
• Client—This option installs only the client components. The client components do not require an activation code, but are required to administer servers throughout the organization.

3. Click Next to continue.
4. You will be prompted to enter your activation code information. Your Activation Code is a 24-character, alpha-numeric activation code which applies the appropriate license to your installation. You must have a valid activation code to use Double-Take Availability for VMware Infrastructure. Click Next to continue.
5. If you are satisfied with the selections you have made and are ready to begin copying the Double-Take Availability files, click Install.
