Use the information in this section to understand how to turn on debug for Sun Cluster HA for DHCP.
The DHCP component has a DEBUG file under /opt/SUNWscdhc/etc.
This file allows you to turn debug on for the DHCP resource on a particular node within Sun Cluster. If you require debug to be turned on for the DHCP resource across the whole Sun Cluster, you will need to repeat this step on all nodes within Sun Cluster.
Edit /etc/syslog.conf
Edit /etc/syslog.conf and change daemon.notice to daemon.debug
# grep daemon /etc/syslog.conf *.err;kern.debug;daemon.notice;mail.crit /var/adm/messages *.alert;kern.err;daemon.err operator # |
Change the daemon.notice to daemon.debug and restart syslogd. Note that the output below, from the command grep daemon /etc/syslog.conf, shows that daemon.debug has now been set.
# grep daemon /etc/syslog.conf *.err;kern.debug;daemon.debug;mail.crit /var/adm/messages *.alert;kern.err;daemon.err operator # # pkill -1 syslogd # |
Edit /opt/SUNWscdhc/etc/config
Edit /opt/SUNWscdhc/etc/config and change DEBUG= to DEBUG=ALL or DEBUG=resource
# cat /opt/SUNWscdhc/etc/config # # Copyright 2003 Sun Microsystems, Inc. All rights reserved. # Use is subject to license terms. # # Usage: # DEBUG=<RESOURCE_NAME> or ALL # DEBUG=ALL # |
To turn off debug, simply reverse the steps above.
