ResiliencyDefaultPeriod = Duration (in seconds) to allow VM to run on a isolated Node with status "Unmonitored" (before the VMs are switched to another Node.)


Change the ResiliencyDefaultPeriod (Default = 240):

(Get-Cluster).ResiliencyDefaultPeriod = <value>


Additional Information

  • Service "VMMS" stopped -> Node = Up & VMs = Up (Can't change Setting of VM or Hyper-V Node)
  • Service "SCVMMAgent" stopped -> Node = Up & VMs = Up (VM-Status in VMM = "Host Not Responding")
  • Host not reachable (NIC disabled) -> Node = Isolated & VMs = Unmonitored
  • If Hyper-V Node is in Status Isolated: After ResiliencyDefaultPeriod -> Node = Down & VMs = switched to another ClusterNode)
