If you are only deploying a few new clusters across your network, then applying the latest HPC Pack service pack to each head node prior to deploying its compute nodes is a pretty simple workflow. You install your head node in your favorite way (either by walking through the setup wizard, or by using the unattended installation command line options to setup.exe), then you install the service pack (interactively or via unattended command line installation), reboot, and you are ready to rock and roll - any compute node that you deploy from that head node will automatically have the service pack version of the files installed.
But what if you are deploying a dozen different clusters? Then the extra 5 minutes per head node to install the service pack & reboot starts to add up!
In that case you can follow this very simple procedure to create an installation folder on your network that can be used to create a new head node with the service pack already 'built-in.'
The new installation folder that you created is now ready to use. Any head node that you install from this new installation point will automatically have the latest service pack files installed, and any compute nodes deployed from that head node will of course also have the latest service pack files installed automatically.
If you want to make an integrated Service Pack 1 installation point follow these steps: (Since SP2 has already been released, you should follow the instructions above so that you have the latest supported software!)
