After configuring the system role for the ST source and granting management privilege to the ST target, you must configure the ST target and create the secure tunnel. For more information about secure tunnels, see About secure tunnels for Unitrends systems.
1 Verify that all requirements have been met. See Replication requirements.
2 Open a new tab in your browser, and connect to the ST target system.
3 Select Replication > Replication Wizard. On the welcome page, click Next to begin cross-replication setup.
4 The wizard asks how you would like to configure the system. Click Cross-Replication so it is highlighted. Click Next.
5 If you have not configured the system for cross-replication, the wizard prompts you to change the installation type. Select Install as a local backup system and a vault (Cross-Replication). (If you have already configured the system for cross-replication, the wizard skips to the next step.) Click Next.
6 The wizard asks you to select a source to replicate to the ST source. Perform one of the following:
• If the ST target system has not been added to the ST source system’s hosts file, select Add a new Source in the drop-down menu. Enter the hostname and IP address of the ST source system in the specified fields. Be sure to enter the hostname exactly as it displays in the hosts file on the ST source. Click Next.
• If the ST target system has already been added to the ST source system’s hosts file, select it in the drop-down menu. Click Next.
To create a secure tunnel
7 Check the box that reads I agree that STsource can manage my system. This allows the ST source system to manage the ST target. Click Next to begin creating a secure tunnel.
8 The wizard asks if you would like the ST target system to be the secure tunnel target. Select Yes, I would like STtarget to be the Secure Tunnel Target and STsource to be the Secure Tunnel Source. Click Next.
9 At the top of the Create Secure Tunnel Target page, the network settings for the connection display. These settings are used to create the secure tunnel interface. Use the default IP, subnet, and port unless these settings cause a conflict in your environment. If necessary, enter your own values. Click Create a Secure Tunnel Target.
10 A message displays asking if you are sure you want to proceed. Once you create a secure tunnel, this procedure cannot be undone. If you are ready to create a secure tunnel, click Yes to proceed with signing the secure tunnel certificate request.
Note: If the cross-replication setup process is interrupted after Step 10, the wizard will automatically skip this step when you start over with the setup process. This is not an error, as a secure tunnel can only be created once. When the wizard skips this step, proceed to Step 11.
11 Click Sign Request. You are prompted to browse and open the file <STsource>.csr you saved earlier. By opening the file, you sign the certificate. Click Okay and save the signed certificate file called <STsource>.<STtarget>-.crt in a convenient location.
12 You are prompted to save the Certificate Authority file. Click Okay and save the file called <STtarget>-ca.crt in a convenient location.
13 You are prompted to send the certificate files and other information to the secure tunnel source system for final configuration. Click Okay.
To continue replication setup, you must return to the ST source system and configure the secure tunnel. Proceed to Configure the secure tunnel for cross-replication.
