Platform: VMware, Hyper-V
Product Edition: Enterprise, Enterprise Plus
Undo-VBRFailoverPlan -FailoverPlan <VBRFailoverPlan> [-Wait] [-WhatIf] [-Confirm] [<CommonParameters>]
This cmdlet undoes the failover process. Undoing failover switches the workload back to source VMs. All changes that were made to the replicas during failover are discarded.
To switch back to the production VM and synchronize the changes made to the replica while failover, start a failback process. Run Start-VBRViReplicaFailback or Start-VBRHvReplicaFailback to fail back to the VMware or Hyper-V production VM respectively. Note that failback is not a group process and must be performed for each VM individually.
Specifies the array of failover plans you want to undo.
Use this parameter to manage undoing multiple failover processes.
If indicated, the next undo failover process will wait for the previous to end.
Specifies whether the cmdlet writes a message that describes the effects of running the cmdlet without actually performing any action.
Specifies whether the cmdlet displays a prompt that asks if the user is sure that they want to continue.
This cmdlet supports Microsoft PowerShell common parameters. For more information on common parameters, see the About CommonParameters section of Microsoft Docs.
