3 node Cluster in Azure contains “weak event was created” in FCM after install of KB2750149 #azure #templates #winserv #SQL

Just created a 3 node SQL cluster in windows Azure and used Templates with windows 2012 with SQL and find a nasty bug. All fixed with a update but still annoying.  I was hoping to get a full patched system. With atleast all the hoxfixes in them. But even in Azure keep your patching up to date!

Building Windows 2012 Clusters in Azure needs patching !

Build my Azure Cluster with AV Set on a 3 node cluster with a fileshare witness.  But even in Azure keep your patching up to date!

As you can see little bugs are still there and if you don’t know about this you could run into trouble.

Below is all the hoxfix information you need.

When installing this update to a Windows 2012 Cluster Server, you will receive the below error when you select Roles or Nodes from within Failover Cluster Manager.

A weak event was created and it lives on the wrong object, there is a very high chance this will fail, please review and make changes on your code to prevent this issue

You can still manage your Cluster from a node that does not have this fix or through Powershell.  The recommendation at this time is to remove and not install this fix.

This issue has been resolved.  After installing the KB2750149 patch for .NET Framework, please also install the below patch.

Failover Cluster Management snap-in crashes after you install update 2750149 on a Windows Server 2012-based failover cluster

But how cool is that SQL availability groups in azure and even a Cluster in Azure ! And the deployment was really fast.

More about this later My Azure credit is gone ;-(

The Cloud OS: It’s Time! Today is the date that Windows Server 2012 R2 is GA (General Availability) #winserv #hyperv

You could already download windows server 2012 R2 from teched or msdn but now the R2 product is general availability

At the heart of the Microsoft Cloud OS vision, Windows Server 2012 R2 brings Microsoft’s experience delivering global-scale cloud services into your infrastructure. Windows Server 2012 R2 offers exciting new features and enhancements across virtualization, storage, networking, virtual desktop infrastructure, access and information protection, and more.

These are new Posters for Windows Server 2012 R2 including Hyper-v 3.0

 

Microsoft Windows Server 2012 R2 Hyper-V Component Architecture Poster and Hyper-V Mini-Posters

 

  • Generation 2 Virtual Machines GA
  • Hyper-V and Failover Clustering GA
  • Session Modes GA
  • Upgrading Your Private Cloud GA
  • Live Migration GA
  • Hyper-V Storage GA
  • Hyper-V Virtual Hard Disk Sharing GA
  • Windows Server 2012 R2 Hyper-V Component Architecture GA

 

Hyper-V Server is a dedicated stand-alone product that contains the hypervisor, Windows Server driver model, virtualization capabilities, and supporting components such as failover clustering, but does not contain the robust set of features and roles as the Windows Server operating system. As a result, Hyper-V Server produces a small footprint and requires minimal overhead. Organizations consolidating servers where no new Windows Server licenses are required or where the servers being consolidated are running an alternative OS may want to consider Hyper-V Server.

 

What’s New in Windows Server 2012 R2

This content focuses on changes that will potentially have the greatest impact on your use of this release.

Windows Server 2012 R2 update thoughts hyper-v virtual Ethernet adapter network cable unplugged

If you update a windows server 2012 to the R2 version and you have teamed the Network card you could end in trouble. Especially if you run hyper-v.

You could find this in your device manager. No way to uninstall the network adapter and even with show hidden devices. you will see the Vnics but are unable to uninstall them.

Cleaning the register is also no option you don’t have the rights to do this only the trusted installer has rights. yes you could change this but is this the best decision ? I don’t thinks so

hyper-v virtual Ethernet adapter network cable unplugged

So here you are with several vnic’s and stuck in your system, uninstalling hyper-v is the best option but you will need to import all the virtual machines. yes you can us PowerShell and scripts to do this but if you have this situation the wmi objects are also stuck and most scripts won’t work.

Create a new switch and new networks next to the old stuff and leaf the old nics disabled is an option but not the best method. ( IMHO )

Fix it and see if the networks are gone and working well to avoid feature problems is the best approach.

there is one line to fix this :

netcfg –u vms_pp 

Remember after running this all the Virtual Machines on this machine are lost their network card. you will need to add the new network card to the VM and assign it to the new switch. this can be done by PowerShell quick and easy.

after this you have one healthy Hyper-v Server or Cluster

Windows Azure new memory-intensive VM size (two CPU cores with 14 GB of RAM)
