This document shows step by step how to run a Reconfigure Hardware plan to simulate a hardware refresh to gain an understanding of the impact of replacing the hardware in a cluster
From the splash screen the first step is to scope to the cluster you wish to simulate removing the host from, on the left hand side click the Search button then click Clusters then select the cluster you are targeting.
After you have selected the cluster the screen will redraw with the supply chain on the left scoped to the cluster you have selected. You should see the correct number of Hosts and VMs shown for the cluster you are targeting, in my scenario this is 6 hosts and 25 VMs
Next click on Plan at the top right of the screen, this will take you into Plan view with the scope you have selected as the basis for the simulation you are performing.
Next select the Reconfigure Hardware option on the Select Plan Type screen
You will now be presented with a list of the hosts in the cluster so you can select the host or hosts you are trying to replace, click on Groups then select the name of your cluster and click Replace
You will the be presented with a list of existing templates to select the type of hardware you want to simulate running the workloads in the cluster on. It is also possible to create your own templates by going into Settings then Templates from the main page, you can then use the New Template option and follow the wizard to create a template for the specifications of the hardware you are planning to purchase.
In my plan I will select the HP DL980 G7 as the template to base my plan on, to do this I select the Host Template from the list and click Replace
Next click the Run option in the top right hand corner
The plan will now execute, when completed you will see the result of the simulation which will tell you how many of the new hosts you would need to host the existing workloads, in my example 5 of the new hosts were needed
