Overview

You have recently deployed SolarWinds HA with additional polling engines (APEs). Everything is working fine, but suddenly you had a SQL DB transaction log full issue because the Orion database is on a SQL Server cluster with Full Recovery Mode.

Your SQL DBA team performed maintenance and fixed the transaction log issue. Now one of the APEs is showing as down and HA Status is showing partially operational.

 

You see following error message in the Orion Web Console whenever you navigate to some links in settings or try to do a failover test:

Server Error

We are having difficulty communicating with the Orion server.

There is no error in licensing and HA logs and license status is synced and normal in the License manager.

Cause

Likely due to poller(s) are not in sync with the last Orion database.

Resolution

Steps:
  1. Disable the HA globally or a specific HA pool;
  2. Run the Configuration Wizard (Primary HA);
  3. After running the Configuration Wizard, do the same on APE that is reporting as down;
  4. Enable the HA globally or a specific HA pool;
  5. Wait about 10 minutes and see if the HA Server changes its status.
