Create a New Hyper-V High Availability Scenario

For Hyper-V, it is possible to perform switchover at the individual VM level, rather than the whole Hyper-V server, which means you need a separate HA scenario for every virtual machine in the Hyper-V environment. To make scenario creation easier, you can select multiple VMs from the Master that inherit the same scenario properties. This 'multiple VM' scenario is then split into sub-scenarios so you can manage each virtual machine independently.

To create a new Hyper-V HA Scenario

  1. Start Manager. Select File, Create, New Scenario or click the New Scenario button.

    The Welcome dialog opens.

  2. Click Create a New Scenario and type a Scenario Group Name, or select one from the list and then click Next.

    Note: If you do not assign a Scenario Group Name, all scenarios you create default to the Scenarios Group. This group becomes part of the scenario name and updates automatically to Hyper-V after the scenario wizard is completed.

    The Select Server and Product Type dialog opens.

  3. Select MS Hyper-V, High Availability Scenario (HA) and then click Next.

    The Master and Replica Hosts dialog opens.

  4. Type a Scenario Name, enter the Hostname or IP Address and Port number for both Master and Replica servers, enable the Verify Engine on Hosts option, and then click Next.

    You may be prompted for user credentials. If so, enter the appropriate credentials and click OK.

    If you enabled engine verification, the Engine Verification dialog opens.

  5. Wait for verification to complete. Click Install to install the Engine on the specified hosts or click Next.

    The Database for Replication dialog opens, listing the auto-discovered virtual machines found on the Master server you specified. By default, all virtual machines are selected for replication. For HA, the entire VM with all related files must be selected.

  6. Select or clear virtual machines for replication and click Next.

    The Scenario Properties dialog opens.

  7. Change properties, as desired, and then click Next. For more information, see the Arcserve RHA Administration Guide.

    The Master and Replica Properties dialog opens.

  8. Change properties, as desired, and then click Next. Scheduled Bookmarks are automatically set to On with a default of 1 hour, but you may adjust the schedule, if needed. For more information, see the Arcserve RHA Administration Guide.

    Wait while the Switchover Properties dialog retrieves information.

  9. When Switchover Properties opens, select Click to edit VN mappings.

    The Virtual Network Mappings dialog opens.

    Virtual Network Mappings

  10. Map the virtual machines listed to the desired virtual networks on the Replica and select the Replica adapter setting method.
    Apply master adapter information

    Specifies that the virtual machines on the replica use the same network adapter information as that of the master.

    Customize adapter information

    Specifies that you can manually enter the IP address, DNS, WINS, and Gateway information for the virtual machines.

    Note: For virtual machines having boot volume on a dynamic disk, sometimes the network information does not configure successfully after switchover. You may have to manually set the IP address after the virtual machine starts up.

    Limitation: If Hyper-v scenario protected VM sys volume is dynamic disk, some network mapping settings can't apply to the replica VM during Swithcover process. RHA doesn't support network mapping for this type virtual machine.

  11. Set any other switchover properties, as desired, and click Next.

    The Switchover and Reverse Replication Initiation dialog opens. We recommend setting Switchover to Automatic and Reverse Replication to Manual.

  12. Choose the desired method for initiating switchover and reverse replication and click Next.

    Wait while the Scenario Verification process completes.

    If Scenario Verification lists any errors, you must resolve them to continue. If any warnings are listed, you should also resolve them to successfully continue. After making changes, click Retry to repeat verification.

    Click Next.

    The Scenario Run dialog opens.

  13. Click Run Now to start synchronization and activate the scenario. Click Finish to run the scenario later.
