Building Microsoft System Center Cloud – SCVMM 2012 R2 – Add hosts and clusters to the Fabric

Add hosts to the fabric

Now we can add our hosts (our cluster).

  • Add Resources – Hyper-V Hosts and Clusters
    • Use pre-created Run As Account. You should never add hosts using own user credentials or using VMM service account.
    • Now you can search all machines in AD.
    • Pick the whole cluster or standalone Hyper-V host.
    • Default host group is just fine for our small environment.
    • Wait for the jobs and you are done.
      • It is possible that you will need a restart because of your Multipath I/O (MPIO) but that can wait till next maintenance window. In my case I will do it right now.

Test added cluster

Just for fun I will measure how long it takes to do a restart of my node that currently holds all VMs.

  • PowerShell
$a = Get-Date; Restart-Computer -ComputerName conthostclu0n0 -Wait -Delay 1; $b = Get-Date; $b - $a
  • And after manual live migration.

Validate added cluster

Now it is a good time to run validation on the clusters that was added to the VMM.

  • Validate Cluster
  • Check the results.
