Create and Run the Recovery Scenario

To restore applications and data to the bare metal machine, create a recovery scenario. The recovery scenario restores the operating system, required applications, and data from the replica to the bare metal machine. After you restore applications and data, the switchover process runs to start the bare metal machine as the master server. The switchover process can be automatic or manual. You specify the switchover type while creating the recovery scenario.

Note: Before you can create and run the recovery scenario, the bare metal machine must be available on the network.

Follow these steps:

  1. Log in to Arcserve RHA as an Administrator and open the RHA Manager.
  2. Click Scenario Management from the Quick Start pane to open the Arcserve RHA Manager.
  3. Select the scenario that performed failover and click Run.

    The Restore Data Wizard opens.

  4. Enter the IP address assigned to the bare metal machine in the Destination IP and Click Verify.

    Note: The source IP address is automatically populated.

    RHA verifies both the machines and displays the verification result in the Status section.

  5. Click Next.

    The Volume Mapping screen opens.

    Restore Data Wizard - Volume Mapping screen.

  6. From the Volume Mapping you select the source volumes that you want to restore on the destination. Click each volume on the source to select or exclude volumes. Based on the selected source volumes, RHA automatically maps the destination volumes. When you are running BMR on the original hardware, you see similar volumes on the Destination.

    Custom disk mapping: Right-click source volumes to open the Custom disk mapping dialog. The Custom disk mapping lets you manually map the source volumes to destination volumes.

    Preserve Existing Volumes on Destination: This option lets you keep the current volume on the bare metal machine (destination machine). All check boxes are cleared from the source and you have to manually map the disk using the Custom disk mapping dialog.

    In some cases you want to change the existing disk and volume layout of the destination, for example, you want to create dynamic disks on the source. To create new disk and volume layout on the destination machine, you can use the DiskPart command. For more information about the DiskPart command, see Creating Dynamic Disks Using the DiskPart Command.

    After you create the disk and volumes, click Refresh to see new disks and volumes.

    Note: Be aware of the following considerations:

  7. Click Next.

    The Switchover Properties screen opens.

  8. Map the replica network adapters to the master server network adapters. For servers in a workgroup, use Redirect DNS. To use Redirect DNS, specify domain administrator credentials. Click Next.

    The Switchover Type screen opens.

  9. Select the synchronization type.
    Switchover automatically

    Indicates that the switchover happens automatically after the recovery scenario restores applications and data.

    Switchover manually

    Indicates that you have initiated the switchover manually. Select this option if you want to verify restored applications and data before the switchover.

  10. Click Next.

    The Run dialog opens.

  11. Select the synchronization method and click OK.

    run

    File Synchronization

    Specifies that synchronization happens at file level.

    Block Synchronization

    Specifies that synchronization happens at block level.

    Offline Synchronization

    Specifies that synchronization happens manually, data is replicated to an external device and then from the device to the Replica server. This method is effective for transferring huge data volumes with low network bandwidth.

    Perform the following steps to run offline synchronization:
    1. Check the Event log for the folder name.

    event log

    1. Log in to the appliance server and locate the VSS mount point folder.

    VSS mount point folder

    1. Manually copy the data from the VSS path created on the appliance server or the virtual machine generated by switchover to an external device or optical media (DVD-R, CD-R).

      Physically transport the external media to the BMR server. During transport, the production dataset caches any changes in the source data in the Replica spool.

    2. Copy the data that is stored on the external media to the required root directory on the BMR server.
    3. Use a copy utility such as xcopy or fastcopy to copy all files and folders from the appliance server to the BMR server.
      xcopy [Source] [Destination] /E /C /H /R
      

      Data copy starts.

    4. Navigate to the RHA Manager and click the Offline Sync Management button.

      The Block synchronization starts.

After the synchronization process is completed, switchover is initiated if you chose the automatic switchover type. The switchover process shuts down the replica and restarts the bare metal machine as the master server with all required applications and data.
