I’m impressed. It was really easy. I have an old server, 9115-505, 4 GB RAM, with AIX 7.1 TL3 SP0 on it. Almost fresh installation, nothing special. The only special preparation measure, I had to take, was to check DNS configuration. In my test lab the Chef Server has name chef.enfence.net and the name must be resolvable to the right IP address on the client. You can achieve it with proper DNS configuration or with an entry in /etc/hosts.
