13-4 Cluster Configuration and Control Rules

LX Series Configuration Guide

Cluster Configuration and Control Rules

 Your cluster can have only one master unit at any one

time. If you have more than one master at a time, the

configuration will be out of sync, and will only reflect the

changes that were made by the last execution of the

cluster save configuration command.

 After making any cluster changes to a master, your final

step should always be to save the configuration to the

cluster. This is only necessary if you changed one of the

shared cluster attributes. Otherwise, you need only save to

local flash.

 Do not put an individual LX into more than one cluster.

Cross Clustering is not allowed, and will create some issues

while saving and communicating with the cluster.

 The cluster LX nodes must be running the same version of

software in order to be in-sync with each other. New

features are being added all the time to the software, and

the other LX nodes must also be aware of the new

features, so they can be in sync with each other. RULE OF

THUMB: When updating software on a LX in a cluster, use

the cluster update software command, so that the entire

cluster is updated at the same time.

Show Cluster Status This displays the attributes that are currently

being shared with the cluster, and the status of

each node in the cluster. In Sync is normal

status for the nodes, which means they agree

with the master’s configuration. If there is a node

out of sync, there is a brief description of why it

does not agree with the master.
