Managing Serviceguard 13th Edition, February 2007

Configuring Packages and Their Services
Distributing the Configuration
Chapter 6294
• Activate the cluster lock volume group so that the lock disk can be
initialized:
# vgchange -a y /dev/vg01
• Generate the binary configuration file and distribute it across the
nodes.
# cmapplyconf -v -C /etc/cmcluster/cmcl.config -P \
/etc/cmcluster/pkg1/pkg1.config
• If you are using a lock disk, deactivate the cluster lock volume group.
# vgchange -a n /dev/vg01
The cmapplyconf command creates a binary version of the cluster
configuration file and distributes it to all nodes in the cluster. This action
ensures that the contents of the file are consistent across all nodes.
NOTE cmcheckconf and cmapplyconf must be used again any time changes
are made to the cluster and package configuration files.
Testing Cluster and Package Operation
As you configure your Serviceguard cluster, it’s a good idea to test that
the various components of the cluster behave correctly in case of a
failure. See the chapter “Troubleshooting Your Cluster” for an
explanation of how to test that your cluster responds properly in the
event of a package failure, a node failure, or a LAN failure.
