Hyper-V Replication & iSCSI connected disk (Quickstation 4 for Backup) - integration services RRS feed

  • Question

  • Hello,

    is there a way to have a Hyper-V Replication setup where a VM has a direct connected iSCSI disk (Quickstation 4), while VSS and other integration services still work? currently we want to ignore the iSCSI disk for the replica, so we can have backups to Quickstation and still replicate the disk to another server, but unfortunatly when we try to start the Hyper-VM replication it says that there is a direct connected iSCSI disk

    is there a solution around that?

  • How do you mean directly connected iSCSI disk? As a pass-through disk? I'm guessing you are not connecting to iSCSI inside your guest VM?

  • Hi,

    Thanks for posting in our forum!

    It's not very clear what you want to ask.

    All the options you can change during Hyper-V replication are listed in the link below.

    Best Regards,

  • Currently the iSCSI disk is mounted inside the VM. as said it's a RDX Quickstation which will do additional file backups inside the vm.

    we basically want to use replication to have a more available setup, however the servers are close to each other so we want to have another offline backup.

  • I think you have a bigger issue.  Looking at, the location listing all supported hardware for Windows Server, it looks like the Quickstation is not listed as a supported device.  I was thinking there might be an easier way to accomplish your end goal of higher availability, but if the storage is not supported, it limits your options.

  • No. Hyper-V cannot replicate resources that it does not control.

    You could use an in-guest replication technology as an alternative. Worst case, robocopy in a scheduled task.

    If Hyper-V Replica is a requirement then your only option is to re-architect so that the host maintains the iSCSI connection and presents a VHDX to the VM.

  • HYPER-V SHOULD NOT replicate the quickstation.

    Hyper-V 1  <-> Hyper-V 2

        Vm     <-> Vm

         Quickstation will be active on the current "active" vm.

  • I agree with Eric. we cannot do much during the replica process.
