What is resynchronization and why is it needed? Hyper-V Replica provides protection to VMs by tracking and replicating changes to the virtual hard disks (VHDs) of the VM. Hyper-V Replica runs 24 hours, 365 days in a year; for any VM that has been enabled for replication it ensures that the data on the...

In a mixed language environment where the server name or domain name contains international characters, you might encounter an error at the time of enabling replication. The event viewer messages will tell you that “Hyper-V failed to enable replication for virtual machine” and “The server name or address...

As part of setting up a replication relationship, Hyper-V Replica transfers the initial VHDs over the network – depending on the size of the VHD, this operation can be time consuming and also impacts your production network. Once initial replication is completed, Hyper-V Replica tracks the changes to...

David is one of our Premier Field Engineers and he approached us with an interesting problem where the customer was encountering a Kerberos error when trying to create a replication relationship. On first glance, the setup looked very straight forward and all our standard debugging steps did not reveal...

Hey, it's Lalithra again. In the last part , we talked about what resource metering is. Now, we’ll get into how to use it with PowerShell. A quick note: if this is your first foray into PowerShell, here are some resources you may find helpful to go through. First, a couple of posts from the...

Hi, I’m Lalithra Fernando, a program manager on the Hyper-V team, working in various areas including clustering and authorization, as well as with our Hyper-V MVPs. In this post, I’ll be talking about resource metering, a new feature in Hyper-V in Windows Server 2012. As you’ve probably...

We have seen multiple queries on the steps required to create the Hyper-V Replica Broker using Powershell, a previous post describes the process but adding more details on the end to end workflow. To create a Hyper-V Replica Broker in a DHCP environment, use the following cmdlets: 1: #Specify the name...

In the first two parts of this 3-part series, you learnt about Test Failover (TFO) and Planned Failover (PFO). In this closing part of the series, I will talk about unplanned failover and summarize the differences of these 3. 1. What is Unplanned Failover? Unplanned Failover is an operation initiated...

This post discusses a subtle change in the certificate workflow for Hyper-V Replica in Windows Server 2012 Release Candidate build and beyond. Note : The pre-requisites certificate based authentication remains unchanged (as seen in an earlier post “ Hyper-V Replica - Prerequisites for...

The certificate requirements for Hyper-V Replica were discussed earlier – this post provides details on how to request a certificate from a Certification Authority (CA), which can then be used for Hyper-V Replica for certificate based authentication. Step #1: Create an INF file Copy-paste the text below...

Continuing from where we left off the last time … Q1: The Replication Health pane has loads of information, how do I interpret these attributes? I thought you would never ask On both the Primary and Replica VM, the following attributes are displayed...

In Windows Server 2012 Release Candidate, Hyper-V administrators can monitor the ‘health’ of the replicating VMs using the Replication Health attribute . This property allows administrators to answer common questions such as: When did the primary and replica VMs last synchronize...
