  • Sorry for the delay.

    So it's likely that there does exist kind of network issues in your cluster.

    I've several question here:

    1. Which topology did you choose in the network configuration step?

    2. Is the firewall settings handled by HPC or manually handled by yourself?

    You can also run a pre-deployment check (PDC) to address port issues:

    1. Launch Cluster Manager on HN

    2. Click Diagnostics in the Navigation panel (bottom left corner)

    3. Click Tests

    4. Locate <Deployment: Ports Open Test>, right-click on it and choose Run

    5. No need to change the settings in the pop-up dialog, just click Run

    6. Go to Test Results to see the result (you may have to wait for a few seconds before the test finishes)

  • Please make sure that:

    1. You input the correct HN name when installing the CN

    2. There was no network issue between the HN and the CN

    When the CN is in the cluster. Its state should be Unknown & Unapproved. A template must be assigned to it to make it a usable node.

  • Thank you very much for responding me. I did input the the correct HN name when installing the CN and I could see the HN name in CN. The network is well between the HN and CN. I found nothing in Unapproved or Unknown column in HN manager. Is there any other possibilities solving this question?

  • Where did you see the HN name in a CN?

    Is it in the Cluster Manager? Or in the registry key?

  • I saw it in the HPC Cluster Manager

  • When you launch the Cluster Manager on a CN, it actually talks to the services on the HN.

    So, do you mean you saw only the HN in both the Cluster Manager on the HN and the one on the CN?

    If so, the registry keys on the CN must be correct since it can locate where HN is and we might have to run some diagnostics tests to address the potential network issues.

  • where is the registry keys on the CN? How can I judge them right or wrong?

  • Please check Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HPC.

    There are two keys named ClusterName and InstalledRole.

    On your HN, the values should be "HN's name" and "HN BN CN".

    On your CN, the values should be "HN's name" and "CN".

  • I just checked the registry keys as you told me, and I found 

    On my HN, the values are "HN's name" and "HN BN CN".

    On my CN, the values are "HN's name" and "CN".

    They are correct, so I am more confused about what the problem is. I just cannot see the CN name either in the HN HPC cluster manager or in the CN HPC cluster manager.

  • 1. The topology of my network is "All nodes only on an enterprise network"

    2. The firewall settings was handled by HPC when I configure HPC, however, I thought later the problem  may be the caused by the firewall, so I turned off it.

    And I did the test, it succeeded.

    Thank you for the help.

  • dear friend:

    I've already solved the problem. My network port is broken and I changed another port and the problem solved.

    Anyway, thank you very much for your help!

    Best wishes.

  • Just curious. Do you mean physical port on the machine?
