Build a UCM in VMWare

As mad as it sounds, you can build a functioning CS1000 Unified Communications Manager (UCM) on a Mac in VMWare. Perhaps its a bit academic, or even pointless, but it's a good way to get comfortable with loading, building and patching the Avaya Linux Base on a wet Sunday afternoon. It's an interesting exercise as well.

Remember the (7.5) Linux Base is essentially Red Hat 5, and requires:

  1. 40GB Hard drive
  2. 2048MB RAM
  3. 2 ethernet adapters
  4. Optionally 2 cores (but one works fine)

If these requirements are not met, the installer will notify you and quit, so they must be set up correctly in the virtual machine environment first (steps 7-10 below). Note that in VMWare the hard drive is an auto-expanding file, but set to 40GB. A full installation with patching will take about 16GB of real disk space. When you're finished, just delete the virtual machine to reclaim this space.

You also need to have an active network connection on the same network as your UCM. Open the network preference pane, hit the plus sign, from the drop down choose an active interface (indicated green) and click Create. Now select your new interface and edit the IP address to put your Mac on the TLAN network. Click Apply.

Remember, always do your UCM configuration on the TLAN, Avaya recommends it, and it honestly works better.

Finally, edit the hosts file in order to browse to the FQDN (fully qualified domain name). Note, if you browse to the IP address you will get the "local login", if you browse to the FQDN, you will get the "Base Manager" - after the primary security server is built.
