Remove an HPE Synergy Composer from the appliance cluster

Use this procedure to remove a reachable appliance from the appliance cluster in HPE OneView.

You will need to remove the appliance from the cluster before removing the Synergy Composer from the enclosure for service or replacement.

Only a standby appliance can be removed from the appliance cluster. To remove the active appliance from the cluster, you must activate the standby appliance so that both appliances swap roles.

When the standby appliance is removed from the cluster and if there is an unused appliance that is powered on and available, that unused appliance assumes the role of the standby appliance if:

  • The unused appliance is powered on.

  • The unused appliance is same model as the active appliance.

  • The unused appliance runs the same version of HPE OneView as the active appliance.

Otherwise, the active appliance becomes a standalone appliance.
IMPORTANT:

Removing an appliance from cluster resets that appliance to its original factory settings and then powers it off. That appliance cannot join the cluster until it is powered on. For more information, see Power on the appliance.
