When you try to access the iLO Remote Console on some servers you sometimes get the message “Remote Console is unavailable. It is already in use by a different client”. But there is no other client connected to the iLO on that server. How can you “reset” the Remote Console connection (from remote) to access the server through the iLO again?
Solve the problen by simply going to “Administration -> Settings -> Network -> Apply” (no changes to settings and just applying the current configuration)
It disconnects all connections, you may able to connect the remote console now.

When using the integrated remote console on a HP Blade Server and you get disconnected for whatever reason you get the error message “The Integrated Remote Console is unavailable; it is already in use by a different client.”.
This is a common problem and is apparently working as intended, though it can be annoying. To fix this you need to turn on “Remote console acquire” within the iLO of the system.
Log into iLO and select Remote Console / Settings
There you will see settings that allow you to enable:
– Remote Console Acquire
Acquire allows you to terminate the current remote console session to attach a new one. The current user is notified.
You can also click on Remote Console Share but you will need to purchase another license key for the functionality of having multiple users using the remote console at the same time.
One more solution:
If you’re using HP iLO (Integrated lights out) and get this message it is because another user is either using the iLO or somehow it’s locked up.
One way to get around this is to reset it under the web settings for the iLO if you have access to it. Under the System Status tab, you can go into diagnostics and there is a button to reset iLO2.
Note that will kick off anyone currently using it, but who cares as long as it helps you right?
