The Integrated Remote Console is unavailable, it is already in use by a different client.

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.
