If any of the node from the cluster has been discontinued for use permanently, you should update the active appliances to stop trying to replicate to this inactive node to avoid having replication backlog. Follow below steps on currently active nodes to update status of inactive node.

1. Login into the appliance as strongauth user.
2. Startup a new Shell window and log into strongkeylite database as skles user.

   shell> mys

3. Run below query to change the replication status to Inactive for server that has been out of use.

   mysql> update servers set status='Inactive', replication_status='Inactive' where sid=<SID>;

   If you are unsure of the SID number assigned to inactive appliance, run below query to find out the SID number and then use that SID number to replace argument in above query.

   mysql> select sid, fqdn from servers;

4. Run below query to confirm that the change has only been applied to the inactive server.

   mysql> select * from servers\G

5. Exit out of database.

   mysql> exit

6. Restart Glassfish/Payara for changes to take effect.

   shell> sudo service glaffishd restart

7. Set KC-PINs.
