4.3 Restarting a Service
The method to use to restart a service depends whether or not improved availability is in effect for that
service.
Improved Availability Is Not in Effect
Use the following command line syntax to restart an individual service on the current node:
# service servicename restart
Note:
Some services do not provide a restart option. For such services, you must issue a service stop
command followed by a service start command.
Use the pdsh command command with the service command to restart a service on the designated
nodes:
# pdsh -w nodename "/sbin/service servicename restart"
Use the following command from the head node to restart all services:
# service --full-restart
Improved Availability Is in Effect
If improved availability is in effect, you must restart the nagios service (that is, the Nagios master) using
your system's availability tool. Following is an example of how to restart the nagios service using HP
Serviceguard. This example restarts the Nagios master, which is running on node n128.
1. Run the /usr/local/cmcluster/bin/cmviewcl command to determine which node the Nagios
master is running on.
# /usr/local/cmcluster/bin/cmviewcl | grep nagios
nagios.n128 up running enabled n128
2. Restart Nagios using the following Serviceguard commands.
# /usr/local/cmcluster/bin/cmhaltpkg nagios.n128
# /usr/local/cmcluster/bin/cmrunpkg -n n128 nagios.n128
# /usr/local/cmcluster/bin/cmmodpkg -e nagios.n128
