Chapter 5228
Configuring the Cluster
This section describes how to define the basic cluster configuration. This
must be done on a system that is not part of a Serviceguard cluster (that
is, on which Serviceguard is installed but not configured).
NOTE You can use Serviceguard Manager to configure a cluster: open the
System Management Homepage (SMH) and choose Tools->
Serviceguard Manager. See “Using Serviceguard Manager” on page 30
for more information.
To use Serviceguard commands to configure the cluster, follow directions
in the remainder of this section.
Use the cmquerycl command to specify a set of nodes to be included in
the cluster and to generate a template for the cluster configuration file.
IMPORTANT See the entry for NODE_NAME under “Cluster Configuration Parameters”
on page 156 for important information about restrictions on the node
name.
Here is an example of the command (enter it all one line):
cmquerycl -v -C $SGCONF/clust1.config -n ftsys9 -n ftsys10
This creates a template file, by default
/etc/cmcluster/clust1.config. In this output file, keywords are
separated from definitions by white space. Comments are permitted, and
must be preceded by a pound sign (#) in the far left column.
NOTE HP strongly recommends that you modify the file so as to send heartbeat
over all possible networks.
