NSX – Host Preparation

After you have installed your NSX Manager and created the NSX Controller cluster, the next step in the process is to prepare the ESXi hosts! This post is the next in my NSX series and will cover NSX – Host Preparation!

When preparing ESXi hosts, ALL hosts in the cluster must be prepped. If we don’t prepare all hosts in the cluster a VM could potentially move to a host that is not running a distributed firewall which would expose the VM to the network… not a good idea!!

I’ve chosen to prepare my cluster below, which consists of three ESXi 6.0 hosts. Navigate to the Web Client > Networking & Security > Installation > Host Preparation. Choose your NSX Manager (I have two vCenter each with a NSX Manager) then select the cluster and click the Install link.

The ESXi hosts do not need to be placed into maintenance mode to prepare them for NSX, this can even be done with active workloads on the hosts.

Once completed, the status will change to the version of code running in the cluster. In my case, that’s version 6.2.0. There should also be a Ready checkmark next to each host with a Firewall status of Enabled.
