SCVMM 2016 - Unsupported Cluster Configuration Error for all VMs


  • Hello,

    I have 4 node Storage Spaces Direct (S2D) cluster with two adapter. One for serving client and other one is for the Cluster only. In switch it is configured as trunk mode. The primary is serving PROD Vlan subnet and secondary virtual adapter has cluster only but no vlan been set but VLAN been enabled without IP set on the core switch.  In SCVMM 2016 of the virtual machines for the S2D cluster are getting the error as follows. Sometimes we are able to manage sometimes all options are disabled.
    Error (13921)
    The highly available virtual machine (VM03) is not supported by VMM because one or more of its network adapters is not configured correctly.
    Recommended Action
    Ensure that all of the virtual network adapters are either disconnected or connected to highly available virtual switches.

    The virtual switch is created, is there any document to verify the Virtual Network setup to fix this issue. Perhaps we are missing something or the VLAN gateway should be configured for the secondary adapter on Hosts. 

    This is annoying and giving big headache. But on other aspect all VM's are communicating and live migration works perfectly.  

    Any suggestion and help appreciated.
