Best practices require that multi-appliance TeamWorks deployments have three active Search appliances.
Never remove from service more than one Search appliance at a time.
Always Make sure that the appliance is back in service as soon as possible.
Allowing extended search-appliance downtime risks creating a split-brain situation wherein multiple appliances have taken on the primary-node role.
CAUTION:After the appliance is decommissioned and permanently removed from service, make sure that you replace it as soon as possible.
IMPORTANT:If running this process breaks your TeamWorks system, you must contact Micro Focus Support for help with repairing it.
