Managing Node Clusters; Creating A New Cluster - Symantec 10521146 - Network Security 7120 Administration Manual

Managing node clusters

Creating a new cluster

Clusters are based on a hierarchy consisting of one central master node that
receives information from and manages multiple slave nodes. The Network
Security console provides a way to configure slave nodes by logging into the
master node from the Network Security console, and to view events and
incidents from them. This section describes how to set up a cluster hierarchy
and manage it:
Creating a new cluster
■
Managing an established cluster
■
Setting a cluster-wide parameter
■
Backup up cluster-wide data
■
In a cluster, one node acts as the master or primary node to which all other
nodes in the cluster synchronize. By default, the first node added under the
Enterprise location object acts as master node, and all subsequent nodes act as
slave nodes. Superusers can change the status by setting a new node as the
cluster master. SuperUsers can also assign a standby node to provide high
availability for either a slave or master node, in case of an emergency failure.
This section includes the following topics:
Building a cluster
■
Establishing a master node
■
Adding slave nodes to clusters
■
Deleting nodes from clusters
■
Building a cluster
The installation process automatically creates an object in the topology tree to
represent the first software or appliance node. This defaults to master node
status, and the installation program automatically assigns it a node number of 1.
By default, all software and appliance nodes installed in the network after this
master node default to slave node status. The master node synchronizes the
databases on all slave nodes in a cluster to its topology, detection and response
policy, and configuration databases.
This section describes the order in which to add nodes to build a node cluster.
