About Cluster Management

The Cluster Management screen is located at Administration > IWSVA Configuration > Cluster Management and is used to configure the HA cluster. The cluster settings are saved in the cluster configuration file and used by the Central Management feature and the HA Agent to create the HA policies and failover priorities. Changing the weight values of the cluster members allow manual parent/active member selection, but may also cause a switchover to occur.

Cluster Configuration

Cluster configurations are settings that are replicated cluster-wide and every HA member is configured with the same cluster configuration information. The Central Management and Cluster Management components use cluster information to provide rapid failover without loss to critical policy and configuration information.

The cluster configuration file, cluster.ini, is stored in the /etc/iscan folder and is used to store the HA cluster settings. You can configure the following elements of a cluster through the Web console Cluster Management page:

• Cluster Name—The name of the cluster

• Cluster Description—The description of the cluster

• Cluster IP Address—The floating management IP address of the cluster is always associated with the active node

• Weighted Priority Election—Enable or disable (default)

• Cluster Members—The list of the nodes belonging to the HA cluster with login access provided to child node.

For this version of IWSVA, the following items are not configurable:

• Cluster Deployment Mode—Always Transparent Bridge mode.

• HA Mode—Always active/passive.

Node Configuration

Node configuration settings are applied to a specific HA member and are not cluster-wide settings. These node-specific settings are never synchronized between the HA members. Node specific settings include the following:

• Hostname—The name of the node

• Role—Either parent or child

• IP Address—The IP address used on the heartbeat port. If this is empty, a new IP will be negotiated between the cluster members and written to the IP address parameter.

• Weight—The weight of the node. Valid values are 1-255. The higher the weight, the greater the chance the node will be selected to act as the parent node.

• Status—Status of the node. Green is up, red is down.

• Last Synchronization—Gives the date and time of the last successful synchronization

• Synchronization Status—Green is successful, red is failed. If failed, a reason displays in the tooltip.
