The start-up mode attribute specifies whether a logical cluster starts automatically when the cluster starts, or whether the administrator starts it manually.
In automatic mode, a logical cluster starts when any of its base instances come online following a cluster restart. Failover instances automatically come online if other failover instances are currently online. This is the default value.
In manual mode, a logical cluster comes online only after the administrator executes the online command.
For example, to change the start-up mode for “SalesLC” to manual, enter:
sp_cluster logical, "set", SalesLC, startup, manual
