HOTHOTHOT!!! Network configurator will not see all NICs

    Question

  • I have a small cluster with two nodes (one head, one compute) with an onboard 4-port 1Gb network switch and a Broadcom 10Gb dual port card.  Plan is to use PrivateApplication configuration (private/application networks local to the cluster).

    When I try to do any network configuration - either through the network configurator or through Set-HPCNetwork - the 10Gb cards are not appearing, and I cannot configure them.  Further, I renamed two interfaces (NIC2 and NIC3) to more descriptive name so I don't lose my place, and the configurator will not detect the new names.

    I've manually configured the IPs on these interfaces, and they are responding to ping requests from each other.

    Help!  I can't use my Application network at all!

  • I had to do a full reinstall of HPC Pack to fix this issue - but this is a really invasive approach.  Is there a better one?

  • I had the same with my Infiniband card. A reinstall didn't help. I try HPC Pack 2016, HPC Pack 2016 Update1 with fixes and HPC Pack 2016 Update2 with fixes. Nothing works.

    Under HPC Pack 2012R2 all works fine. Any help?

  • Hi,

    What is the OS version of your HPC Pack 2016 head node? And what is the OS version of your HPC Pack 2012 R2 head node?

    Could you collect the HpcManagement logs at c:\Program Files\HPC Pack 2016\Data\Logs\Management\HpcManagement_*.bin on your HPC Pack 2016 head node and share to hpcpack@microsoft.com?

  • Hi,

    the OS version for HPC Pack 2016 is Server 2016 standard and for HPC Pack 2012R2 is Server 2012R2.

    I find out that if I restart the HPC Management Service I get my configured Adapter.

    First it looks like this:

    PS C:\Windows\system32> Get-HpcNetworkInterface

    Name                 Type                 IpAddress            SubnetMask
    ----                 ----                 ---------            ----------
    HP FlexFabric 10G... Private              192.168.201.1        255.255.255.0
    HP FlexFabric 10G... Enterprise           10.130.32.77         255.255.240.0

    After restarting the service there is my third adapter.

    PS C:\Windows\system32> Get-HpcNetworkInterface

    Name                 Type                 IpAddress            SubnetMask
    ----                 ----                 ---------            ----------
    HP FlexFabric 10G... Private              192.168.201.1        255.255.255.0
    Mellanox ConnectX... Application          192.168.202.1        255.255.255.0
    HP FlexFabric 10G... Enterprise           10.130.32.77         255.255.240.0

    I will also send you my Management logs. Thanks for your help.

  • Now, I got it to work. I have reinstalled the hole Server. I didn't do the HPC configuration until I installed the Update2 Fixes.
