Azure HCI certification-HLK: not sufficient machines

Hi,

I have to do a Azure HCI certification so I setup the environment the following way:

  • 2x Azure OS Nodes für Azure HCI Cluster, cluster is created and runs normally
  • 1x Server with HyperV: 1x VM (AD DS, DNS, DHCP), 1x VM (Admin Center), 1x VM (HLK), 1x VM (PCS)

All seems to work so I want to start the HLK test "S2D Prepare Machibnes for Tests".
But I always get an yellow triangle and it is said the following:

There are not sufficient machines avalable to fill one or more of the machines set roles.

I read many times through all Docs but I can't find the root issue.

Thanks for help.

Greeting

Chris

    Hi,

    for all who have the same problem:

    If you not install the Admin Center to the same Node you want to manage, you have to create a WinRM HTTPs Listener at each Node who should be manageable via Admin Center.

    I will close this case.

    Thanks for help.

    Hi Daniel,

    great to hear :)

    I also found something strange:

    If I mark the test and press F1 there are information that I need a minimum of 3x nodes in my cluster.

    I will have a call with a microsoft colleague during the day, maybe this is the solution

    Thanks for your efforts.

    Hi Daniel,

    thanks for feedback and I already talked to my Microsoft contact person.

    For now it seems to be a bug in HLK software.

    I will keep this post update-to-date.

    Hi,

    I still have no solution for the issue so I decided to re-create the Azure HCI Cluster.
    This time I want to use the latest Admin Center but in time I have to start the Cluster Validation, I get the following issue:

    Error in cluster validation
    8:28:54 AM
    Source
    Go to Cluster Creation.
    Type
    Error
    Message
    Could not validate cluster. Error: (1) RemoteException: The WinRM client cannot process the request. Default authentication may be used with an IP address under the following conditions: the transport is HTTPS or the destination is in the TrustedHosts list, and explicit credentials are provided. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts list might not be authenticated. For more information on how to set TrustedHosts run the following command: winrm help config. (2) RemoteException: Unable to connect to 192.168.155.12 via WMI. This may be due to networking issues or firewall configuration on 192.168.155.12. (3) RemoteException: Could not find CimSession with the given ComputerName = 192.168.155.12**

    192.168.155.12 is one of the Cluster Nodes.

    For now I tried the following things:

    • deactivating Firewall at both Nodes and on the Admin Center Server
    • WinRM Quickconfig at both Nodes
    • Added The AdminCenter to the trusted Host List of both Nodes

    Maybe it is important:

    My Admin Center Server is a virtual Server 2019 DC Evaluation System (17763.1432) on a Hyper-V Server. Ping is working normally from Admin Center to both Nodes.

    What can I do to fix this issue?

    Thanks for help.
