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

8.2.1.4 Cluster Information Program daemon (clinfo)
This daemon provides status information about the cluster to cluster nodes
and clients and invokes the
response to a cluster event. The
and clients. However, it is a prerequisite for running the clstat utility.
With RSCT (RISC System Cluster Technology) on HACMP/ES Version 4.3,
there are several more daemons.
8.2.1.5 Cluster Topology Services daemon (topsvcsd)
This daemon monitors the status of network adapters in the cluster. All
HACMP/ES cluster nodes must run the
8.2.1.6 Cluster Event Management daemon (emsvcsd)
This daemon matches information about the state of system resources with
information about resource conditions of interest to client programs
(applications, subsystems, and other programs).The
each node of a domain.
8.2.1.7 Cluster Group Services daemon (grpsvcsd)
This daemon manages all of the distributed protocols required for cluster
operation. All HACMP/ES cluster nodes must run the
8.2.1.8 Cluster Globalized Server Daemon daemon (grpglsmd)
This daemon operates as a
adapter membership global across all cluster nodes. All HACMP/ES cluster
nodes must run the

8.2.2 Starting Cluster Services on a Node

You start cluster services on a node by executing the HACMP
/usr/sbin/cluster/etc/rc.cluster
screen to build and execute this command. The
the environment required for HACMP by setting environment variables and
then calls the
daemons. The clstart script is the HACMP script that starts all the cluster
services. It does this by calling the SRC
specified subsystem or group.
Using the C-SPOC utility, you can start cluster services on any node (or on all
nodes) in a cluster by executing the C-SPOC
/usr/sbin/cluster/utilities/cl_rc.cluster
node. The C-SPOC
start cluster services on the nodes specified from the one node. The nodes
