Why are my Hyper-V hosts in VMM reporting “Needs Attention”?

If you are kind of new to System Center VMM console and wondering why after a while your hosts responds “Needs Attention” and checking the host properties and seeing that everything looks green in the status, then continue and read this post!

You can just extend the console by right-click the hosts bar and add the column with “Agent Version Status” and then you can see the reason for host status,

The reason for this “Upgrade Avail” is that the VMM server has been updated with some new patches/updates that came with Windows Update and now you need to update your hosts to have the new agent to properly talk to the VMM Server.

That can of course be done with PowerShell if you have quite some hosts…  You can of course also get the list of which hosts that need an update,

And then with the following command also update the hosts that need to

If you are wondering why I am filtering on Agent-Version -ne “0.0” is because in this environment there are several VMware hosts and they do not have a VMM agent but is recognised as managed hosts and appear when getting the “managed computers”

Good luck 🙂

Nutanix for Hyper-V – the future for your datacenter!

Today I had the opportunity to see an Nutanix deployed cluster with Hyper-V. If you have not heard about Nutanix before I urge you to go and check out their website and see how it works. Basically their solutions use local storage for massive performance and their Controller VM has direct access to the disks (a set of SSD and HDD) that also has tiering and dedup and present the storage to the Hyper-V node with a SMB 3 file share, for resiliency the data is replicated to other nodes so in case of an failure your VM´s will start up on another node with all the data.

When you buy an Nutanix solution the Windows 2012 R2 is installed on delivery and you will only configure networking and add the nodes to the Active Directory, so getting your Hyper-V enironment up and running is quite a breeze with this 2U x 4 node solution and it can scale with more 2U sets and this can also be added after you are up and running to scale with your added loads!

As you can see on the features you get both TRIM and ODX functionallity with the solution allowing you to clone or create VM´s within the box in just seconds and also reclaim storage when removing data and VM´s! As you will always use the local controller VM there is no need for SMB Multichannel.

The nutanix will work with your System Center environment and can be automated with VMM and Orchestrator.

I will do a more thorough post about the configuration and setup when I get my hands on a Nutanix-platform!

Wait! Are you going to migrate your old legacy VM´s?

So I have in several posts described different ways on moving from one hypervisor to another with your VM´s. There are several different choices when it comes to the transitioning phase, some more automated than others.

But wait!! Yea I know the virtualization is Gods gift to the IT but it also carries some responsibilities. The technique gives you as the IT admin the possibility to run old legacy operating systems almost forever.

One big thing in the Move projects is to also take into account if the workload running can be upgraded within the OS, not just moved to another virtualization platform. Surely you do not want to describe on your CV that in your last employment you had Windows 2003 Servers as Domain Controllers for instance. Compare it with VHS, do you still watch movies and record stuff on the 80/90´s system?

First of all you can use the Microsoft Assessment and Planning toolkit to analyze what of your workloads can be upgraded ( I know, it does not look at your third party server applications that needs some brushing of and upgrading also)

When you have analyzed and got some workloads that can be migrated then check out this page on what tools and wizards you can use to actually smoothen the process for those windows roles and features running on your old and soon to be unsupported OS to an new version! As you can see below, Windows 2008 R2 is coming to the last date of mainstream support!

Yes I know that this often can be a quite burden on the IT department to carry out this kind of transformation projects and for several company-critical applications this can also become a serious cost that someone has to approve or maybe decide to decommission if they live outside of the support window!

Finally the MAT4Move has been released, but where to find it?

Now I found the release of the Migration Automation Toolkit for Double-Take Move. As I described in an earlier post I was waiting for this and now it was released.

It is as described in the readme, a technology preview and for users with PowerShell skills.

And it has not yet appeared on the Gallery but you can find it on the Vision Solutions Support site (where you will need an account to login), and on the Move download page you see it on the top 🙂

 I will write a more thorough article about how the experience to use it compared to the Vision Solutions Double-Take System Center toolkit in a later blog post!

New Toy: Surface 2 RT

09-23SurfaceFamily_Page

So I have been a Apple fan for some while now and yesterday I was at a local electronic store and tested the Surface 2. This resulted in me coming home with an RT 😛

I really like the speed and the functionallity of this device.

Maybe I will start looking at the Pro as the RT has some limits but it is fast and I can take care of several of my daily tasks. Had loved if it was possible to run not just PowerShell but also the ISE. Found some suggestions to utilize Azure IaaS with a RDS desktop with the software and tools not available in the RT and maybe that would work 🙂

By the way, this post was also written on the device, will tomorrow change to the type keyboard instead ….
