Managing Serviceguard 12th Edition, March 2006

Configuring Packages and Their Services
Distributing the Configuration
Chapter 6306
• 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.
Using Distributed Systems Administration Utilities
You can also use Distributed Systems Administration Utilities to send
files and commands to designated systems in your Serviceguard cluster.
These utilities provide the following:
• Configuration synchronization
• Log consolidation
• Command fan-out
With configuration synchronization, you can have confidence that
systems in your Serviceguard cluster are maintained to a standard you
adopt. As you make changes on your configuration master, those changes
are propagated to all your client systems.
With log consolidation, you can examine a single log that contains
entries from all systems in your configuration, in order of their time
stamps, so you can find a specific entry easily.
