Install UDT with High Availability

The following instructions detail how to install an Orion product with a new High Availability (HA) pool or with existing HA pools. Consider these instructions as you install your product.

SolarWinds UDT installation with new HA

These instructions define how to install SolarWinds UDT with a new SolarWinds HA pool. Both primary and secondary servers in the pool must match and have the exact same Orion products and versions installed.

If you have already enabled SolarWinds High Availability, you must disable HA before you can install SolarWinds UDT. All SolarWinds product versions must match on the primary and secondary servers before you can re-enable your HA pools.

For more information on SolarWinds HA, see High Availability in SolarWinds products.

Before you begin, you need the following:

  • A VIP address
  • The secondary HA server
  • An available HA pool license
1. Prepare the secondary server
  1. Reserve an available IP address to use as the Virtual IP (VIP) address on the same subnet as the primary and secondary servers.
  2. Build a standby server on the same subnet as the server you want to protect.
  3. Open port 5671 (TCP) on the primary (incoming) and secondary (outgoing) servers.
  4. Open ports 4369 and 25672 (TCP) on the main Orion server and its secondary server. These ports are not required when protecting additional polling engines.
2. Install on the primary server

Follow the install instructions for the product. Install on the primary server.

Do not run the product installer on the secondary server. The HA process creates the secondary server installer.

3. Activate the HA license

Have your HA license from the Customer Portal to activate prior to creating a pool. The License Manager through the Orion Web Console provides a 30-day evaluation license to test HA features.

  1. Click Settings > All Settings > License Manager.
  2. Select the HA license.
  3. Click Activate.
  4. Enter your license information.
    If you do not have a license key, enable the HA evaluation license.
4. Download and install secondary server

HA provides a downloadable installer from the primary server with a list of all products and versions. This installer ensures both servers match.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Click Setup a new HA server.
  3. In the dialog box, click Get started setting up a server.
  4. In the Setup a High Availability Server dialog box, click Download installer now.
  5. Move the downloaded installer to your secondary server and run it.
    Select which type of backup server you want to install under High Availability.
    Enter your SQL credentials for your Orion SQL database when prompted.
5. Create the HA pool

You can now add the backup server to a pool with your main server or additional polling engine.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Click Setup High Availability pool next to your standby server.
  3. Enter the pool name and the virtual IP (VIP) address.

    The VIP must be unassigned and on the same subnet as the primary and secondary servers.

  4. Click Create Pool to complete the pool setup.

SolarWinds installation with existing HA

These instructions define how to install SolarWinds UDT into an existing server pair in a SolarWinds High Availability (HA) pool. Both primary and secondary servers in the pool must match and have the exact same Orion products and versions installed.

If you have enabled SolarWinds High Availability, you must disable HA before you can install SolarWinds UDT. All SolarWinds product versions must match on the primary and secondary servers before you can re-enable your HA pools.

These instructions assume you have an HA pool already created and enabled. For more information on SolarWinds HA, see High Availability in SolarWinds products.

1. Disable the HA pool

The HA pool must be disabled to begin installation. If you install prior to disabling, the pool is automatically disabled.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Select the pool you want to disable.

  3. Toggle High Availability to Off.

Do not modify the VIP or IP settings for the servers.

2. Install on the primary serverFollow the installation instructions on the primary server.
3. Install on the secondary serverFollow the install instructions on the secondary server.
4. Enable the HA pool

After the servers are installed, enable the HA pool using the following instructions. You may need to recreate the HA pool. For details, see Set up an HA pool for NPM.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Select the pool you want to enable.

  3. Toggle High Availability to On.
    The Orion Web Console verifies all SolarWinds product versions match across the HA pair before enabling. If you receive errors, check your product versions.
