Stopping Cluster Services On A Node - IBM AIX HACMP SG24-5131-00 Hardware User Manual

are started in sequential order - not in parallel. The output of the command
run on the remote node is returned to the originating node. Because the
command is executed remotely, there can be a delay before the command
output is returned.
8.2.2.1 Automatically Restarting Cluster Services
You can optionally have cluster services start whenever the system is
rebooted. If you specify the
restart or both in the Start Cluster Services SMIT screen, the
script adds the following line to the /etc/inittab file.
hacmp:2:wait:/usr/sbin/cluster/etc/rc.cluster -boot> /dev/console 2>&1
# Bring up Cluster
At system boot, this entry causes AIX to execute the
/usr/sbin/cluster/etc/rc.cluster
Note
Be aware that if the cluster services are set to restart automatically at boot
time, you may face problems with node integration after a power failure and
restoration, or you may want to test a node after doing maintenance work
before having it rejoin the cluster.
8.2.2.2 Starting Cluster Services with IP Address Takeover Enabled
If IP address takeover is enabled, the

8.2.3 Stopping Cluster Services on a Node

You stop cluster services on a node by executing the HACMP
/usr/sbin/cluster/etc/clstop
Services SMIT screen to build and execute this command. The
stops an HACMP daemon or daemons. The
services or individual cluster services by calling the SRC command
Using the C-SPOC utility, you can stop cluster services on a single node or on
all nodes in a cluster by executing the C-SPOC
/usr/sbin/cluster/utilities/cl_clstop
C-SPOC
then calls the
nodes. The nodes are stopped in sequential order—not in parallel. The output
of the command that is run on the remote node is returned to the originating
-R
script to configure and start the TCP/IP interfaces and to
/etc/rc.net
script. Use the HACMP for AIX Stop Cluster
