Which setting is required to group all devices in the HA cluster?

To group all devices in a High Availability (HA) cluster, the group name is a fundamental configuration aspect. The group name serves as the identifier for the HA cluster, allowing the devices to recognize each other as part of the same operational group. This identification is essential for ensuring that the devices can coordinate their functions, share state information, and manage failover processes effectively.

When devices are assigned the same group name, they can establish the necessary communication and synchronization mechanisms required for HA functionality. Without a consistent group name across devices, they won't operate cohesively, leading to potential issues in failover and load balancing.

While other settings, such as HA license type, location, and device firmware, play significant roles in the overall configuration and performance of HA clusters, the group name specifically addresses the requirement for devices to be identified and managed as a cohesive unit.
