3.4 Verifying the Installation of a Value-added
Software Module
To confirm that the activation record is accepted and the functionality is enabled, check the log
file at /var/log/emerson_license.log.
When the license is granted for a module, the log message is as follows:
: : : License is valid
There are sufficient logs in the log file to know the status of the licensed software module. If the
functionality of a software module is not enabled, then the log file is updated with the reason
for rejecting the license.
3.5 Returning the License
You can return the license when:
 A value-added software module is not required on a blade any longer.
 The blade is not usable and the license need to be migrated to newer blade.
