Chapter 39 Centralized Management Using Clusters
Managing Clusters
Use the
clustermode
command to switch between different modes.
The prompt in the CLI changes to indicate your current mode.
or
In machine mode, the prompt will include the fully qualified domain name of the machine.
Copying and Moving Settings
All non-restricted (see
) commands have new operations:
CLUSTERSHOW
and
CLUSTERSET
.
CLUSTERSHOW
is used to show in which modes a command is configured
(see
). The
CLUSTERSET
operation allows you to move or copy the
current settings (configurable with the current command) from one mode to another or between levels
(e.g. from a machine to a group).
(e.g. from a machine to a group).
A copy retains the settings for the current mode. A move resets (clears) the configuration of the current
mode; i.e., following a move, no settings will be configured for the current mode.
mode; i.e., following a move, no settings will be configured for the current mode.
For example, if you have configured Good Neighbor Table settings (the
destconfig
command) for group
northamerica
, and you decide that you want the entire cluster to have these settings, you can use the
clusterset
operation from within the
destconfig
command to copy (or move) the current settings to
the cluster mode. (See
.)
Caution
Exercise caution when moving or copying configuration settings to avoid inconsistent dependencies. For
example, if you move or copy listeners with disclaimer stamping configured to another machine, and that
new machine does not have the same disclaimers configured, disclaimer stamping will not be enabled on
the new machine.

Experimenting with New Configurations
One of the most advantageous ways to use clusters is to experiment with new configuration settings. First
you make changes at the machine mode, in an isolated environment. Then, when you are satisfied with
your configuration, you move those configuration changes up to the cluster mode to make them available
on all machines.
