There is no
/var/log/clm.log on the Management Node.
The issue may occur after a Management Node migration to RHEL7.
/var/log directory permissions do not allow pemuser to create a new log file.
Create the file manually:
# touch /var/log/clm.log # chmod a+w /var/log/clm.log
/var/log directory permissions to allow writing to it from all users:
# chmod o+w /var/log
