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).
• To use Serviceguard Manager to configure a cluster, open the System
Management Homepage (SMH) and choose Tools->Serviceguard
Manager.
See “Using Serviceguard Manager” on page 28 for more information.
• To use Serviceguard commands to configure the cluster, follow
directions in the next section.
Using Serviceguard Commands to Configure the
Cluster
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.
Node names must be 39 characters or less.
NOTE Do not include the domain name when specifying the node name; for
example, specify ftsys9 and not ftsys9.cup.hp.com.
Here is an example of the command:
# cmquerycl -v -C /etc/cmcluster/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.
