Building an HA Cluster Configuration

Configuring the Cluster

Chapter 5 249

If the cluster is online, the check also verifies that all the conditions for

the specific change in configuration have been met.

NOTE Using the -k option means that cmcheckconf only checks disk

connectivity to the LVM disks that are identified in the ASCII file.

Omitting the -k option (the default behavior) means that cmcheckconf

tests the connectivity of all LVM disks on all nodes. Using -k can result

in significantly faster operation of the command.

Distributing the Binary Configuration File

After specifying all cluster parameters, apply the configuration. This

action distributes the binary configuration file to all the nodes in the

cluster. HP recommends doing this separately before you configure

packages (as described in the next chapter) so you can verify the cluster

lock, heartbeat networks, and other cluster-level operations by using the

cmviewcl command on the running cluster. Before distributing the

configuration, ensure that your security files permit copying among the

cluster nodes. See “Preparing Your Systems” at the beginning of this

chapter.

Use the following steps to generate the binary configuration file and

distribute the configuration to all nodes in the cluster:

• Activate the cluster lock volume group so that the lock disk can be

initialized:

vgchange -a y /dev/vglock

• Generate the binary configuration file and distribute it:

cmapplyconf -k -v -C /etc/cmcluster/clust1.config

cmapplyconf -k -v -C /etc/cmcluster/clust1.ascii
