These settings are used to control automatic failover behavior when a cluster node member becomes degraded or faulted.

Move Resources - Transfer the Resource Groups from the degraded or faulted node to the healthy node.

Move Resources and disable node - Transfer the Resource groups to the surviving node and disable the degraded or faulted node when it comes back online.

Auto fail-over disabled - Disables HA failover.

Cluster Members Settings

The requirements for configuring HA Cluster members are listed under a dropdown called Requirements. The configuration of the two nodes and the witness is setup under the Configuration dropdown.

Local Node - The IP address of the appliance that is currently being viewed.

Remote Node - The IP address of the other HA cluster member.

Witness - The IP address of the witness.

Heartbeat - Heartbeat network interface directly connecting both cluster nodes.

Common Resource Group Physical Interface - Is a common network interface across all cluster members. It will be designated as a default Resource Group data network. This could be a physical network interface or an aggregate.

Common HA Comms Port (advanced) - HA communication port. This allows changing from the default TCP port 4746.

Configure Cluster Members

  1. Navigate to the HA page.

  2. Scroll down and click the Cluster object.
