Adding a Failover Group

Add a failover group to provide orchestration for virtual machines from the same hypervisor.

Before You Begin

  • To be included in a failover group, virtual machines must already be part of a replication group.
  • For VMware destination sites: To use a failover group for test failover operations, configure a replication target to support test failover operations.

Procedure

  1. From the navigation pane, click Configuration > Replication.

    The Replication page appears.

  2. Click Failover groups.

    The Failover groups page appears.

  3. In the upper-right area of the page, click Add failover group.

    The Add failover group page appears.

  4. Enter the following information:
    • Group name: Enter a descriptive name for the group.
    • Server groups / Hypervisors: You can select server groups or servers (hypervisors) to add all virtual machines that are part of the group or hypervisor and have been configured for replication.

      After adding a group or server, select the check box to the left of each virtual machine that you want to include in the failover group.

    • When you add virtual machines, the table in the Machines area is populated with the following information:
      • Source VM: The source VM.
      • Destination VM: The destination VM at the DR site, based on the configuration of the VM for replication.
      • Last sync time: The time when the snapshot was taken during the latest backup of the source VM.
      • Schedule name: The replication schedule associated with the replication pair.
      • Priority: As needed, set the priority for each virtual machine. VMs with lower priority numbers will be processed first during failover or failback operations.
      • Actions: Click the action action_button button to select an action: Add pre script or Add post script.

        For instructions about how to add pre script options, see Adding a Pre Script.

        For instructions about how to add post script options, see Adding a Post Script.

    • Group details:
      • Delay between different priority machines (in mins): Enter a value in minutes to specify how long the failover or failback operation should wait between processing VMs that are assigned different priorities.

        This setting can be used to enable higher priority machines to start before processing the next set of machines.

      • Continue to next priority on failure: To continue failover or failback operations when a VM cannot be included in the operation, select this option.

        If you do not select this option, the failover or failback operation stops when a VM cannot be processed successfully.

      • Approval required for failover and failback: If failover or failback operations should pend until they are approved by an administrator, select this option.
      • User for approval: Select a user who must approve any failover or failback operations.

        If you selected Approval required for failover and failback, the user must approve the operation before it starts, by clicking the appropriate link in the email that is sent to request approval.

      • Test failover target: (only for VMware destinations) To use the failover group for test failover operations, select a previously defined replication target that has been configured to support test failover operations.
    • Auto failover options: (VMware only) To configure the failover group to monitor VMs and automatically initiate a failover if the VMs in the primary site are disabled or unreachable, enter the following information:
      • Monitoring machines: To identify machines that can monitor the availability of the VMs in the recovery groupfailover group, select three virtual machines that are configured as proxies for the primary site, and then click OK.

        The first proxy selected acts as a coordinator to monitor the source VMs.

      • Delay time before declaring outage: Enter a value in minutes to indicate how long to wait after detecting an outage before initiating a failover.

      When you save the failover group after entering auto failover information, automatic failover is enabled and monitoring begins.

      To disable auto failover, you can click Stop monitoring on the page for the failover group.

  5. Click Save.
