— Virtual Machine Manager 2012 Add Node to running cluster

Categories: VMM

In my little test lab I had to add another node for testing purpose.

Head into Virtual Machine Manager 2012 and add Hyper-V Host and Clusters

Enter the server you want to add to the cluster

image

After AD Validation select the server

image

And add it to Virtual Machine Manager

image

This will enable the Hyper-V role if needed

image

And we can then see the host in Virtual Machine Manager Console , and then use Add Cluster Node

image

Add the host , as this is a test lab I will skip cluster validation , but cluster validation will check storage and network access , service pack levels and a bunch of other things ,so always run it in production

image

One very handy feature is that Virtual Machine Manger will add the Windows Failover Clustering role if not installed, again very handy

And we now have 5 hosts in the lab , almost ready rebuilding VMM to 2012 SP1 CTP so we can add a few Windows8 Hosts

— Settting LimitCPUForMigration Virtual Machine Manager 2012

In my test environment I ran into a issue due to different cpu types.

So we get a 10709 that we are unable to migrate due to different processor features.

This can be fixed by setting “Allow migration to a virtual machine host with a different processor version” , this can also be set in the template so future machines will have this set pr default

Being Lazy I looked up the powershell syntax from http://technet.microsoft.com/en-us/library/hh801556.aspx

And could see that I can use

get-scvirtualmachine | set-scvirtualmachine –limitcpuformigration $true

image

that will create a job pr machine and set the setting for us.

Again powershell saves the day.
