hyper-v replication

Question

we have the following setup:

windows server 2019 datacenter
hyper-v installed
7 RAID partitions

4 VMs:

each VM have 4 VHDX files each on different RAID partitions

We would like to setup replication to another server with the exact configuration with the VHDX file replicating to the same RAID partition:

HOST 1: HOST 2:

VM VHDX config: replication

RAID partition 1 drive D: VHDX file 1--------------------------------- >RAID partition 1 drive D: VHDX file 1
RAID partition 2 drive F: VHDX file 2---------------------------------->RAID partition 2 drive F: VHDX file 2
RAID partition 3 drive G: VHDX file 3--------------------------------->RAID partition 3 drive G: VHDX file 3
RAID partition 4 drive H: VHDX file 4--------------------------------->RAID partition 4 drive H: VHDX file 4

Is this possible with Hyper-v?

Answer 1

What I forget to mention is: the two host servers are in two different data centers in different states.

Answer 2

Hi,
According to your description, you just need to enable replication of your VM, choose the VHDX file you want to replicate and then the location you want to sent.


Here is the doc on how to set up Hyper-V replication:
https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/manage/set-up-hyper-v-replica

What I forget to mention is: the two host servers are in two different data centers in different states.

There is no problem if the two servers can communicate with each other.

Thanks for your time!

Answer 3

when i set that up, it replicates to one drive on the replication server. What i need is for each Virtual drive to map to one of four physical drives on the replication server.

host server drive f:\vm-c.vhdx to replication server physical drive f:\vm-c.vhdx..

host server drive g:\vm-d.vhdx to replication server physical drive g:\vm-d.vhdx..

Answer 4

Hi,
I found another solution and hope it could help at your side:

1. Create initial VM folder on primary host. VM-NAME
   Virtual Machines
   Virtual Hard Disks
   Snapshots
2. When the VM is up and running, export it. This preservers the folder structure I've created.
3. Copy the export to the replica server. Put it in the location I want it. I'll typically rename the top folder as VM-NAME.HVR (hyper-v replica).
4. Import the VM replica on the replica server using the same ID and register in place.
5. On the primary, set up replication to the secondary and specify "use a machine already on the target." HV finds the already-loaded replica and then verifies it's a match by a block-by-block compare. It still takes a bit of time but is faster than a copy and compare.
