Last days I faced power off accident. When everything came back to normality, I realized that although everything is up and running, agents do not report anything to the server. The restart of agents didn't help (by the way described here: IEM client - manual restart). What helped was manual stopping and starting the IBM Endpoing Manager and IBM License Metric Tool servers (2nd by-the-way: restarting Software Use Analysis works exactly the same as restarting metric tool). And because all parts are installed on the same Linux, the task was quite simple:

# /etc/init.d/besserver restart
Stopping IBM Endpoint Manager: BESRootServer: [ OK ]
Starting IBM Endpoint Manager: BESRootServer: [ OK ]
#


# /etc/init.d/beswebreports restart
Stopping IBM Endpoint Manager: BESWebReportsServer: [ OK ]
Starting IBM Endpoint Manager: BESWebReportsServer: [ OK ]
#

# /opt/IBM/LMT/cli/srvstop.sh
Stopping server server1.
Server server1 stopped.
#

# /opt/IBM/LMT/cli/srvstart.sh

Starting server server1.
Server server1 started with process ID 1741.
#

If you want to restart also database, the procedure will be a bit longer:

# /opt/IBM/LMT/cli/srvstop.sh
Stopping server server1.
Server server1 stopped.
#

# /etc/init.d/beswebreports stop
Stopping IBM Endpoint Manager: BESWebReportsServer: [ OK ]
#


# /etc/init.d/besserver stop
Stopping IBM Endpoint Manager: BESRootServer: [ OK ]
#

# su - db2inst1
$
