Retrospective Clustering :)

[Disease]

I have 3 blades that I use for VM and am wondering is there a way to cluster them for failover without affecting the VM's that are on each one at the moment.

 

They are Dual Quad Xeons each with 128GB ram with their own ISCSI volume from our Nimble Storage. In hindsight I wish I have looked into this before creating VMs on them so is there a way to do this after, using Hyper-v by the way.

 

Many Thanks

easy as pie. Once the cluster is setup you simply run a little wizard and it all works.

I was hoping for a little more detail, unless you mean I have to kidnap Harry Potter, push him in the server room and close the door

Yup . That!!!

 

You can set a failover cluster to run on existing nodes, The biggest issue you will face is that you will need to use an IScsi disk as a cluster disk within the cluster. Once setup you just clickly click and it will migrate the disks and config and put them in the cluster. We run a cluster across 6 nodes and have individual local vms on each as well.

So effectively I need a shared Iscsi drive set the current hosts to cluster and it will copy all the VMs on the hosts to the shared cluster?

Yup, Pretty much!. Create the drive, build the cluster around it, add the hardware to the cluster then make each VM HA and migrate the storage.
