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.
