Using Serviceguard Manager to Configure the Cluster
Before you start:
1. Configure the volume groups.
2. If you are using a quorum server to manage the cluster lock, make
sure it is running.
To configure the cluster using Serviceguard Manager, proceed as follows.
Online Help is available at each step to help you make decisions.
1. Create a session on Serviceguard Manager. Select the option for
discovering unused nodes. On the map or tree, from the list of unused
nodes, select the one where you want to start the cluster.
2. From the Actions menu, choose Configuring.
After you give the node’s root password, the Configuration screen
will open, and you will be guided through the process. Each tab
contains related information. Serviceguard Manager discovers much
of the information, so you can choose from available options, such as
lists of volume groups, networks, and nodes.
3. When you complete your information, click Apply. If there are errors,
they are displayed in a log window. If not, the log displays a
“successful” message, and the binary configuration is automatically
distributed to the nodes.
4. After a Refresh, the new cluster configuration and status
information appears in the tree, map and Properties.
To modify or delete the configuration, select the cluster on the tree or
map, and choose Configuring from the Actions menu.
Specifying a Quorum Server
If you will be using a quorum server, be sure to specify the -q qshost
option with the cmquerycl command. For example on a Red Hat
distribution:
# cmquerycl -v -n lp001 -n lp002 -q lp-qs \
-C $SGCONF/lpcluster.config
