An administrator can perform the following steps to check and clean up an Authentication Manager deployment of unwanted replica instances:

1. From the Security Console, view the installed licenses and check to see  if you have a Base or Enterprise license.

• A Base license allows for one replica instance in the Authentication Manager deployment.
• An Enterprise license allows for up to fifteen replica instances.

2. Check the number of replica instances in the Authentication Manager deployment
   1. Check Replication Status of the replicas in the deployment.
   2. Count the number of replica instances or, where there are none, an administrator will get the following warning: 

3. From the Security Console navigate to RADIUS > RADIUS Servers.
   1. ​Check the number of RSA RADIUS Servers that have a type of Replica.
4. Delete any unwanted Authentication Manager replica instances from the deployment where found using the procedure on how to delete a replica instance
5. Deploy a new Authentication Manager replica instance. Depending on the version of the deployment, use one of the following guides:
   • RSA Authentication Manager 8.2 Setup and Configuration Guide, 
   • RSA Authentication Manager 8.2 SP1 Setup and Configuration Guide, or the
   • RSA Authentication Manager 8.3 Setup and Configuration Guide.

Should you still experience an issue deploying and attaching an Authentication Manager replica instance to the Authentication Manager deployment then please contact RSA Customer Support and open a technical support case. Please have your License serial number ready, to speed up the process of opening a case.
