Check the line where it sends data to /dev/console inside the script and modify it. Also you may wish to modify syslog.conf to avoid some other things later.

My file is this

cat /etc/rc.nsr

# Copyright (c) 1990-2006, EMC Corporation

# All rights reserved.

(echo 'starting NetWorker daemons:') > /dev/null
if [ -f /bin/nsrexecd ]; then
if [ -f /bin/NetWorker.clustersvr ]; then
if [ -f /nsr.NetWorker.local -o -h /nsr.NetWorker.local ]; then
if [ -h /nsr ]; then
rm -f /nsr
ln -s /nsr.NetWorker.local /nsr
fi
fi
fi
(/bin/nsrexecd) > /dev/null 2>&1
(echo ' nsrexecd') > /dev/null
fi
if [ -f /bin/lgtolmd ]; then
(/bin/lgtolmd -p /nsr/lic -n 1) > /dev/null 2>&1
(echo ' lgtolmd') > /dev/null
fi
if [ -f /bin/nsrd -a ! -f /bin/NetWorker.clustersvr ]; then
(/bin/nsrd) > /dev/null 2>&1
(echo ' nsrd') > /dev/null
fi
if [ -f /bin/nsrwreg ]; then
(/bin/nsrwreg) > /dev/null 2>&1
fi



And the syslog.conf

# Start of lines added by NetWorker - DO NOT DELETE OR CHANGE THIS LINE
daemon.notice /dev/null
daemon.notice /nsr/logs/messages
daemon.notice operator
local0.notice /nsr/logs/summary
local0.alert root, operator
# DO NOT DELETE OR CHANGE THIS LINE - End of lines added by NetWorker


But the messages continue

I restart the service syslogd and now it's ok .

Thanks !!
