How can I update an FNX license server / FNE failover

See also - Failover license server installation, upgrades and updates.

It is the advantage of the FNE/FNX server, that an update works without downtime. Do the following steps:

Note: If there is not a failover or tertiary server existing, you can skip the steps accordingly.

1. Test the integrity of the downloaded SW on the primary license server:
   
   sh install-fne-<date>-<version>.sh test
   If you get the message "Package integrity verified" you can proceed with the other steps.
   
   
2. Get emergency license for standby emergency license server and install it - just to be prepared
   
   
3. Primary server: Do a dry-run installation on the primary server and look for messages. Example for the dry-run command:
   sudo sh install-fne-<date>-<version>.sh dry-run
   
   
4. Primary server: If there are not any problems reported with the dry-run, do the update on the primary server. Example for the update command (no option used):
   sudo sh install-fne-<date>-<version>.sh
   
   
5. Check e.g. with fne-status, that the primary server is running.
   
   
6. Wait 2 minutes.
   
   
7. Failover server: Do the update also on the failover server. See command above.
   
   
8. Check e.g. with fne-status, that the failover server is running.
   
   
9. Wait 2 minutes.
   
   
10. Check with fne-status, if the FNE failover and (if installed) FNP triad is up again.
    
    
11. Tertiary server: Do the update also on the tertiary server.
    
    
12. Check e.g. with fne-status, that all servers are running. 

If there are any problems, please check, if a switch to the standby emergency license server is reasonable and open a LIST ticket to report the problem.
