I know that this is probably a silly question but is it possible to configure an agent to log out to multiple LEM appliances?
No, unfortunately not.
You could potentially install a second copy of the directory structure and manually install a service, but there might be some weird side effects, especially with FIM if you're using that, too.
For failover we'd recommend using the hostname instead of IP, but it's still just one copy of the data.
Thanks for the quick response nicole pauls! It was a question I received from my engineering team, they didn't specify what the exact use case was. If it's something they push for I will get more use case details and open a feature request. Thanks again!
