Note

The discovery service can only be started on Grid members that are configured as the Consolidator or Probe (i.e. the Grid members with valid Discovery installed).

Each discovery member requires separate Discovery licenses, and must have a running discovery service. Consider the following before starting or stopping the discovery service:

  • The Grid Master does not run the discovery service.
  • Appliances running a Discovery license and the discovery service do not support HA pairs.
  • Discovery Probe appliances appear as Grid members in Grid Manager.
  • All appliances running discovery must have the Discovery license installed before starting the service.
  • Appliances running discovery do not run core network services such as DNS and DHCP. Discovery appliances may also run the NTP service.
  • If you expect to run a single appliance in the Grid for discovery, the appliance is designated as a Consolidator, and also performs Probe discovery operations.
  • When you add a new Grid member with a Discovery license, the appliance is set automatically to the following:
    • A Consolidator, if no other discovery member exists in the Grid.
    • A Probe, when at least one discovery appliance exists in the Grid

Note

When a member joins the Grid and applies a Discovery license for the first time, the admin user needs to log off and log in again to Grid Manager to see the discovery-enabled functionality.

For information about discovery configuration at the service level, see Configuring Discovery Properties.
