Chapter 5234
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 154 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
NOTE In a larger or more complex cluster with many nodes, networks or disks,
the cmquerycl command may take several minutes to complete. To speed
up the configuration process, you can direct the command to return
selected information only by using the -k and -w options:
-k eliminates some disk probing, and does not return information about
potential cluster lock volume groups and lock physical volumes.
-w local lets you specify local network probing, in which LAN
connectivity is verified between interfaces within each node only.
