System shutdown or crash of one cluster node and subsequent reboot of other nodes resulting in the SFW messaging for Live Migration support to fail

Last published : Oct 01, 2026
If a cluster node crashes or shuts down abruptly, then it is noticed that on subsequent reboot of the other remaining cluster nodes, the SFW Configuration Utility for Hyper-V Live Migration Support shows the crashed node as Invalid Configuration. (2509422)
In such cases, the following is observed:
  • The SFW messaging for Live Migration support will not work between the remaining nodes
  • TheVMDg LiveMigrationSupport attribute cannot be set to True for any new VMDg resource
To resolve this issue, it is recommended to first Unconfigure and then Configure the remaining cluster nodes using the SFW Configuration Utility for Hyper-V Live Migration Support through the Solutions Configuration Center (SCC).
