Save the Date: WEBINAR | Scripting & Automation in Hyper-V without SCVMM with @ThomasMaurer

Hi everyone,

you should save the 10th December 2015 in your calender’s. My friend Thomas Maurer is presenting some cool Scripting Stuff for Hyper-V together with Altaro. 🙂

Click here to register for the event.

System Center Virtual Machine Manager (SCVMM) provides some great automation benefits for those organizations that can afford the hefty price tag. However, if SCVMM isn’t a cost effective solution for your business, what are you to do? While VMM certainly makes automation much easier, you can achieve a good level of automation with PowerShell and the applicable PowerShell modules for Hyper-V, clustering, storage, and more.

Are you looking to get grips with automation and scripting?

Join Thomas Maurer, Microsoft Datacenter and Cloud Management MVP, who will use this webinar to show you how to achieve automation in your Hyper-V environments, even if you don’t have SCVMM.

Remember, any task you have to do more than once, should be automated. Bring some sanity to your virtual environment by adding some scripting and automation know-how to your toolbox.

How to get notified and react when a cluster NIC fails

Hi everybody,

today a short day to day helper regarding cluster networks.

Last weekend I had a question from my coworker, if it is possible to react on failed networkconnections within a cluster even if the cluster is still running.

As you know Hyper-V is running as long as the cluster heartbeat is available and the storage is reachable. Only if these connections fail, Hyper-V Cluster forces a node to failover his roles.

My answer, yes it is possible with some tricks. First thing you need to know is, that if a network connection in the cluster failes, we get an error event.

This event is also noticed in the event viewer of your Hyper-V Host. Now you can attach a task to that event and for example run a script which forces a failover.

The script to set the node in maintenance  mode and force a failover could look like:

You can achieve the same effect when you use System Center Operations Manager by configuring an Agent Task for your Hyper-V Host.
