Designating a New Primary RADIUS Server
You can change which server within a realm is designated as the Primary
RADIUS Server for that realm.
To designate a new Primary RADIUS Server:
1Stop the RADIUS service/daemon on the Replica RADIUS Server.
2Log into the Replica RADIUS Server as root (Solaris/Linux) or administrator (Windows).
3Navigate to the ..RSA Radius\Service (Windows) or
/opt/rsa/radius (Solaris/Linux) directory.
4Run the rsainstalltool (Windows) or rsaconfiguretool
(Solaris/Linux) utility with the promote option.
#./rsaconfiguretool
The utility creates a configuration package to change this server to the
Primary server.
5Restart the updated Replica RADIUS Server to make it the new Primary RADIUS Server.
6Publish a new configuration package administratively to configure all Replica RADIUS Servers to use the new Primary RADIUS Server.
After you designate a new Primary RADIUS Server for a realm, you can configure the old Primary RADIUS Server as a Replica RADIUS Server by downloading a configuration package published by the new Primary RADIUS Server.
NOTE: If your old Primary RADIUS Server used aliases to handle authentication requests, you must configure aliases on the new Primary RADIUS Server after you promote it, and you must define an alias on the corresponding Agent Host record in the RSA Authentication Manager (Agent Host > Edit Agent Host > RADIUS Configuration).
Recovering a Replica After a Failed Download
If a Replica RADIUS Server fails during the download of a configuration package, its configuration may be corrupted or it may have a stale secret.
To recover after a failed download:
1Stop the RSA RADIUS service/daemon on the Replica RADIUS Server.
