#/sbin/init.d/syslogd start

4.Stop syslog-ng:

# /sbin/init.d/syslog-ng stop

5.Edit the /etc/rc.config.d/syslog-ng file, as follows:

a.Change the CLOG_CONFIGURED line to CLOG_CONFIGURED=0.

b.Remove all other CLOG lines except for the following:

CLOG_LAYOUTS_DIR=/var/opt/dsau/layouts CLOG_ADDITIONAL_LOG_DIRS[0]=/var/adm/syslog

6.If the TCP protocol was used, remove the following line from /etc/services: clog_tcp port/tcp # Consolidated logging with syslog-ng

3.4.2 Disabling a Serviceguard Cluster Log Consolidation System

Perform the following steps to disable log consolidation in a Serviceguard cluster. Perform these steps on each cluster member:

1.If local syslogs were being consolidated or the UDP protocol was used, edit /etc/ rc.config.d/syslogd and change SYSLOGD_OPTS to remove the -Nswitch. For example:

SYSLOG_OPTS="-D"

2.Stop and restart syslogd with the following commands:

#/sbin/init.d/syslogd stop

#/sbin/init.d/syslogd start

3.If the local syslogs were being consolidated, edit the system’s /etc/syslog.conf file to remove the following lines:

mail.debug

@fully

qualified

hostname

*.info;mail.none

@fully

qualified

hostname

Where fully qualified hostname is the fully qualified hostname of this system. Note that a <tab> precedes each @ sign.

4.Halt the clog package with the command:

#/usr/sbin/cmhaltpkg clog

5.Stop syslog-ngwith the following command:

# /sbin/init.d/syslog-ng stop

(This stops the syslog-ngdaemon and package log consolidation if configured.)

6.Edit the /etc/rc.config.d/syslog-ng file and change the CLOG_CONFIGURED line to the following:

CLOG_CONFIGURED=0

Remove all other CLOG lines except for:

CLOG_LAYOUTS_DIR=/var/opt/dsau/layouts CLOG_ADDITIONAL_LOG_DIRS[0]=/var/adm/syslog

7.Delete the clog package with the following command:

# cmdeleteconf -p clog

3.4.3Disabling a Standalone Log Forwarding Client

Perform the following steps to disable log forwarding on a standalone client:
