Debug Sun Cluster HA for DHCP

Read 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 on debug 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, to repeat this step on all nodes within Sun Cluster.

How to turn on debug for Sun Cluster HA for DHCP

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. The output below, from the command grep daemon /etc/syslog.conf, shows that daemon.debug has been set.

*.alert;kern.err;daemon.err                    operator
#
# pkill -1 syslogd
#

Edit /opt/SUNWscdhc/etc/config and change DEBUG= to DEBUG=ALL or DEBUG=resource.
