Sun Cluster 3.1 Data Service for DHCP

How to turn debug on for Sun Cluster HA for DHCP

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.

  1. 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
    #
  2. Edit /opt/SUNWscdhc/etc/config

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


    # cat /opt/SUNWscdhc/etc/config

    #
    # Usage:
    #       DEBUG=<RESOURCE_NAME> or ALL
    #
    DEBUG=ALL
    #

    Note –

    To turn off debug, simply reverse the steps above.
