Failed to download or run the Scalability Engine installer from the main server

Updated March 7, 2018

 

Overview

The Scalability Engine installer for Additional Polling Engines, Additional Websites, and High Availability backup servers could not be downloaded from the main Orion server or times out.

Environment

Additional polling engines or additional web servers for products running on Orion Platform products.

 

Cause 

Each installation file has a download timeout of 30 minutes from the main polling engine to additional systems. After trying to download the installer three times, the download fails. 

Resolution

Ensure connectivity to the server hosting the main polling engine

  1. Check the connectivity in your network from the main polling engine to other systems receiving the installations. These systems include Additional Polling Engines (APE), Additional Web Servers (AWS), and High Availability (HA)  backup servers.
  2. Take actions to improve data transfer between the systems on your domain to reduce download times and complete the installation within 30 minutes.

Workaround I 

For products running on Orion Platform 2016.1 to Orion Platform 2017.3 Hotfix 3.

If the above is not possible you can try this workaround:

  1. Run the Scalability Engines installer again on the Additional Polling Engine, Additional Web Server, or on the High Availability backup server you are upgrading and click through until you see a screen right before downloading starts.
  2. Copy ‘C:\ProgramData\Solarwinds\Installers\CoreInstaller.msi’ as well as MIBs.msi from the main server to server you are upgrading to the following location: %temp%\SWOrionSetup[currenttimestamp]\subinstallers\CORE_2017.x\

  3. Resume from where you left off in Step #1 with the installation of the Additional Poller \ Web \ HA Backup using the Scalability Engines Installer.

The upgrade completes successfully.

Any unresolved network connectivity issues between Additional Poller \ Web \ HA Backup and the main polling engine or SQL server may cause you further problems going forward if this is not addressed.

Workaround II 

For products running on Orion Platform 2017.3 Hotfix 4 or later, using the SolarWinds Orion Installer.

If you have multiple Additional Polling Engines in your environment, and the installation completed successfully on at least one of them, complete the steps below:

  1. Log on to the Additional Polling Engine where the Scalability Engine Installer completed successfully, and navigate to C:\ProgramData\SolarWinds\Installers.
  2. Copy and paste the entire contents of the Installers folder from the working Additional Polling Engine over to the to the C:\ProgramData\SolarWinds\Installers directory on the Additional Polling Engine that is having the issues with the installer.
  3. Run the SolarWinds Orion Installer on the Additional Polling Engine with the problem - Now the files will not try to be downloaded but simply loaded from the Install Folder once the Installer executes.
