CHAPTER 13 Configuring the Cluster
Configuration and
Control Feature
The Cluster Configuration and Control (C3) feature saves time and effort by
allowing you to propagate changes to any or all units in a cluster, without
having to script or manually configure each unit individually. This also allows
rapid recovery and replacement if there should be a problem any
where within
the cluster.
The editor or interface for this feature is either the LX CLI or the Configuration
GUI (Graphic User Interface). Both are easy to use, and both interfaces allow
you to perform changes and propagate them to all units that are cluster
members.
Cluster Configuration and Control also provides a mechanism for updating
software (both
linuxito and ppciboot) to all units within a cluster. You can
schedule updates using the time-of-day rules feature to set when the updates
done. This allows you to preschedule when updates will run - you don’t even
have to be there.
You can share any or all configuration attributes to all units in a cluster. You
can also unshare any or all of the same administrator configurable attributes
from the cluster, and keep those attributes local.
At any time you can view cluster status, including which units are in the
cluster, the health of individual units, and lists of all the shared attributes and
settings. You can also view the synchronization status. If attributes are not
synchronized, the reason is displayed.
