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.
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.
| Parameter | Description | Default |
|---|---|---|
failoverSiteTimeoutSeconds |
How often the system checks for a recovered home site while connected to a failover site. | 300 s (5 min) |
offlineTimeoutSeconds |
How often the system retries connecting when all sites are unreachable. | 300 s (5 min) |
Tip:
Lower values mean faster recovery but slightly more network traffic. The default of 5 minutes is a good balance for most environments.
