This object reports the actual, settled outcome of the chassis-management election described by the related NMEStatus object, whether this CPU card is currently acting as the master, chassis server, or is in a slave role deferring to another card. An admin reads this to confirm which specific card in a multi-CPU chassis is actually in control at any given moment, as opposed to merely contending for that role. For example, a card reporting master(2) here is the one actively serving as this chassis's management point, while any others would report slave(1).
