Imprivata Failover & Recovery

Goal

Ensure uninterrupted authentication by automatically:

• Switching to a failover site when all configured home sites are unavailable.
• Periodically checking whether a home site has recovered.
• Switching back to a working home site without user interaction.
• Recovering automatically from offline mode when any site becomes reachable.

Prerequisites

Before you begin, ensure the following:

• eLux 7.2601.0 or later is installed.
• Imprivata is configured and operational.
• A valid bootstrap URL is defined.
• Network access to home and failover sites is properly configured.
• Administrative access to run network test commands (for validation scenarios).

How Failover Recovery Works

Normal Operation

• The device connects to a configured home site.
• Authentication works as expected.

Home Site Unavailable

• If the home site become unreachable, the device automatically switches to a configured failover site.
• Users can continue logging in without interruption.
• While connected to the failover site, the device periodically checks whether a home site is available again.

Automatic Switch Back

• Every failoverSiteTimeoutSeconds (default: 5 minutes), the device attempts to contact the home sites.
• As soon as a home site responds, the device automatically switches back.
• No user interaction is required.

Offline Mode

If both home and failover sites are unreachable:

• The device enters offline mode.
• Authentication is not possible.
• Every offlineTimeoutSeconds (default: 5 minutes), the device retries all configured sites.
• As soon as any site becomes reachable, the system reconnects automatically.

Configuration

Failover behavior can be configured either locally or centrally.

• Local file: /setup/terminal.ini
• Central management: Configurable via device profile in Scout

Failover behavior is controlled under the “Imprivata” section.

Tip:

Lower values mean faster recovery but slightly more network traffic. The default of 5 minutes is a good balance for most environments.
