Step A: Get Ready for the Install

Save Your Files

During the kickstart part of a clean install, all the files on the node are permanently deleted. Before you begin, you must first copy important files to another location.

1. Locate the following files on the node, in the /home/elemental directory:

   • The installer for the Elemental software version you are downgrading to.

     Example: elemental_production_conductor_file_2.14.0.12345.run

     If you do not have this file, you can download it again at AWS Elemental Support Center Activations.

   • Your license file or files. They will either be a set of .lic files or a single .tgz file.

   • Any custom scripts or other assets you wish to keep.

2. Copy these files to a directory on another system. For example:

   • Use Windows Share protocol: Connect to \\<node IP>\elemental on a PC.

   • Use Samba: Connect to smb://<node IP>/elemental on a Mac.

Download Files

Download the installation files for each unique AWS Elemental product that you're using.

To download installation files

1. Log in to AWS Elemental Support Center Activations. For detailed steps to download installation files, see Downloading AWS Elemental Conductor File Software.

2. Download your files.

   You need the following files for each unique piece of AWS Elemental software that you're installing.

   • A kickstart (.iso) file for creating a USB boot drive. For example, centos-20161028T12270-production-usb.iso.

     You use this file to put a preconfigured installation of your operating system on your physical machine.

   • An installation (.run) file for the AWS Elemental software itself. For example, elemental_production_conductor_file_2.15.3.44452.run.

     Make sure that you download the right version of software for the processing architecture that you need, either CPU-only or GPU-enabled.

   For example, if you're installing AWS Elemental Conductor File on two systems and AWS Elemental Server on five systems, you need to download two .iso files and two .run files.
