Procedure

1. In Neverfail Engine Management Server (EMS) navigate to Management > Deploy.
2. Select one of the following depending on the environment you intend to support:
   • Add a stand-by server for high availability, go to Step 3
   • Add a stand-by server for disaster recovery, go to Step 7
     
     Note: You can also create a stand-by VM for Disaster Recovery for an existing High Availability pair, and vice-versa.
     
     The Add a Stand-by Sever for High Availability page is displayed.
3. Select the Clone type step – select to use manual cloning. Click Next.
   
   The Select channel IP addresses step is displayed.
4. Select the NIC which is to host the Channel IP addresses. Enter the Channel IP addresses for the Primary and Secondary servers. Manually enter the subnet mask or leave blank to set to the default subnet mask. If you are adding high-availability to an existing DR pair, enter the IP addresses and associated information for the Secondary-Tertiary and Tertiary-Primary (when deployed) Channel. Click Next.
   
   The Ready to complete step is displayed.
5. Review the information on the Ready to Complete step and if accurate, click Finish to prepare the Secondary server for manual cloning using a third-party tool. During the pre-condition check, the following status messages will display:
   • Shutting down Neverfail Software on all Nodes of (HOSTNAME)
   • Reconfiguring Engine to participate in an extended cluster
   • Waiting for server to become Active
   • Completed reconfiguration of Engine
   • PRIMARY server ready to be cloned. Please clone the PRIMARY
     
     Once cloning process is complete, start the new stand-by server. The servers will connect and begin replication automatically.
6. Once complete, perform Post Installation Configuration tasks as listed in the Neverfail Continuity Engine v8.0 Installation Guide.
7. On the Neverfail Continuity Engine Management Service user interface, click the Add a stand-by server for Disaster Recovery.
   
   The Add a stand-by server for disaster recovery page is displayed.
8. Select either of the following:
   • The public (principal) IP address will be identical to the Primary server.
   • The public (principal) IP address will be different than the Primary server - you must add credentials to be used for updating DNS.
     
     Click Next.
     
     The Select Channel IP Addresses step is displayed.
9. Enter the Neverfail Channel IP addresses for the Primary and Secondary servers. Manually enter the subnet mask or leave blank to set to the default subnet mask. If you are adding Disaster Recovery to an existing pair, then enter the IP Addresses and associated information for the Primary-Tertiary and Secondary-Tertiary channels. Click Next.
   
   The Select Clone Type step is displayed.
10. Select the Select manual cloning option. Click Next.
    
    The Ready to Complete step is displayed.
11. Review the information on the Ready to Complete step and if accurate, click Finish to prepare the Secondary server for manual cloning using a third party tool. During the pre-condition check, the following status messages will display:
    • Shutting down Neverfail Software on all Nodes of (HOSTNAME)
    • Reconfiguring Engine to participate in an extended cluster
    • Waiting for server to become Active
    • Completed reconfiguration of Engine
    • PRIMARY server ready to be cloned. Please clone the PRIMARY

Once cloning process is complete, start the new stand-by server. The servers will connect and begin replication automatically. Once complete, perform Post Installation Configuration tasks as listed in this guide.
