This is the standard RowStatus control for creating, activating, or removing a redundant-slot-pair entry in the c64SlotTable, following the usual conceptual-row lifecycle. An admin configuring hardware redundancy between two specific slots for the first time would use createAndGo here to establish that slot pairing, since simply having two matching cards installed doesn't create the redundancy relationship without this table entry. Setting an existing pairing's status to destroy(6) removes that specific redundancy configuration, requiring it to be reconfigured before those two slots would back each other up again.
