Managing node clusters
To build a cluster
1 Install new nodes as slave nodes.
Establish one master node to serve as the sync node.
■
Slave nodes will automatically run the database sync process.
See "Establishing a master node"
2 Add the new node into the topology map.
See "Adding nodes and objects"
Use the passphrase as established during installation of that node.
■
Use the node number.
■
3 Create a master high-availability configuration.
See "Establishing high availability failover"
Note: Upgrading node clusters requires special consideration. See the Symantec
Network Security Installation Guide for more details.
Establishing a master node
This section describes how to establish a cluster master node using the Network
Security console.
Note: To deploy a 7100 Series node as a slave, the master node must be either a
Symantec Network Security 4.0 node or another 7100 Series node.
To set a cluster master
1 In the Network Security console, click Admin > Node > Set As Cluster
Master.
2 In Select Node, choose a node from the pull-down list, and click OK.
3 In Warning, click OK to confirm the setting, and restart the old master
node, the new master node, and the Network Security console.
Caution: Use Set As Cluster Master only if the master node in a cluster fails.
After the original master comes back online, we recommend that you wait for at
least 5 minutes before making any changes to give the returned node time to be
fully initialized back into the cluster. Then, if you want to return the node to
master status, force a database synchronization. This triggers the node to
regenerate communication passwords with each slave node.
