Guest Cluster (Shared Virtual Hard Disk) in windows server 2012 R2 HyperV

    Question

  • Dears 

    I deployed windows server data center 2012R2 Fail-over cluster CSV between two nodes

    Node1: windows server 2012 R2 Data center

    Node2: windows server 2012 R2 Data center

    ,then create VMs in CSV, now the VMS is working fine with high availability , 

    After that I want to deployed High availability between two VMs , as a guest cluster, I added SCSI controller with Virtual shared Hard disk on VM1, "VHDx" and I enabled the shared option,

    my question how the second VM2 can see the shared Virtual shard hard disk ?


    Thanks in advanced,

  • Hi Sir,

    This shared disk can be used for cluster shared volume and cluster quorum disk .

    Generally , even number cluster nodes needs a quorum disk .

    AFAIK , DAG doesn't rely on cluster shared volume . What you need is quorum disk.

    You may add the quorum disk (the shared virtual disk you added for cluster) in cluster manager .

     

    As for further assistance of exchange cluster ,you may post it into exchange forum:

  • Hi

    Simply just add the newly created to VM2 also as a existing disk

  • Dear Andreas,

    I do the following on VM2:

    1- go the Setting -- Select -- ScSI controller -- Hard disk -- Add--- then select Browse - and select the existing Hard disk that I create for VM1

    Is that correct ?

    Thanks in advanced,

    >>1- go the Setting -- Select -- ScSI controller -- Hard disk -- Add--- then select Browse - and select the existing Hard disk that I create for VM1

    Yes (created one VHDX file in first VM cluster node and enable 'shared vhdx' , then , browse that vhdx for second vm cluster node and also enable 'shared vhdx').

    And that VHDX file should be put into CSV volume or SOFS share .
