Step A: Get Ready for the Install - AWS Elemental Server

This is version 2.16 of the AWS Elemental Server documentation. This is the latest version. For prior versions, see the Previous Versions section of AWS Elemental Conductor File and AWS Elemental Server Documentation.

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. Therefore, you must first copy important files to another location. These files appear in the list in the table below.

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

    File Description

    elemental_production_servern.n.n.nnnnn.run

    where n.n.n.nnnnn is the version you want to downgrade to, for example 2.51.12345

    The installer for the version that you are downgrading to.
    database_backups/elemental-db-backup_server_n.n.n.nnnnn_yyyy-mm-dd_hh-mm-ss.tar The database backup that was automatically created when you upgraded from this version, in a compressed, aggregated format.
    activation_xxxx-<random characters>.key The activation key for your license, present only if you installed software yourself.
    lic-download-<hostname>.tgz Aggregated, compressed file with all your license files. You will either have this file, or a set of individual .lic files.
    eme.lic A license for AWS Elemental Server.
    ui.lic A license for AWS Elemental Server.
    cable.lic The license for the Cable Labs option, if installed.
  2. Copy these files to a directory on another system, using the protocol compatible with your equipment. 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.

Locate Files to be Downloaded

  1. Find the version of the software that you're downgrading to.

    Follow these steps:

    1. From a Linux prompt, log in to the hardware until with the elemental user credentials.

    2. Look for the desired installer as shown here.

      [elemental@hostname ~] ls

      Look for the file named similar to this ...elemental_production_server_2.15.0.123456.run...

  2. If you find the software, skip to Step B: Install (Kickstart) the Operating System Software.

    If the software isn't on the hardware unit, go to the next step.

  3. From your regular workstation, open a web browser, go to the AWS Elemental User Community, click Downloads and Licenses, and download the software for the version that you're going to.

  4. Make a note of where downloads are stored on your workstation. For example:

    h:/corporate/downloads/.
  5. Make a note of the name of the download file. For example: elemental_production_server_dg_version_short;.0.123456.run

  6. Copy the download file from your workstation to /home/elemental/ on one of the nodes. For example:

    • Use SFTP protocol and an FTP client application on your workstation computer. Connect to the IP address for AWS Elemental Delta on port 22 with the elemental user credentials and transfer the file.

    • Use SCP protocol and an SCP client application on your workstation computer. Copy the file with the elemental user credentials and transfer the file.

  7. Repeat the download to any other nodes that are changing versions. If you're changing versions on several nodes, copy the download file to every hardware unit at once. Doing so reduces downtime on each node as you start installing the new software.
