Power-Shell Scripts to build Win2012 Hyper V Cluster
How will it happen ?
- A new cluster is built with no attached SAN.
- It will perform naming on the cluster networks. Note that I’ve used converged fabrics via a virtual switch.
- Execution via called Add-VMsToCluster which will then scan all the cluster nodes for existing VMs to make them HA mode.
- Add-VMsToCluster will run a workflow which will in turn add VMs to the cluster in parallel.
