UCS MMC Server will not start after power fail

We run a UCS Kopano Server. This server was switched off by a power fail.
After restarting the Kopano Server with all Mail is working. But when I try to log on the Management Console I get an error. It tells me to restart the univention-management-server and web-server by console.
If I try to do so, I get following Message:
Warning: univention-management-console-server.service changed on disk. Run ‘systemctl daemon-reload’ to reload units.

Running systemctl does not have effect. What can I do?
