Abstract
According to one aspect, a Fiber Channel (FC) switch that is currently serving as a Principal Switch among a plurality of FC switches in a FC Fabric sends an Exchange Fabric Parameters (EFP) frame having an empty domain identifier list to neighboring FC switches during a first portion a Principal Switch Selection phase. During a second portion of the Principal Switch Selection phase that is after the first portion, the first Fiber Channel switch sends to neighboring FC switches an EFP frame having a non-empty domain identifier list to indicate to the neighboring FC switches that the first FC switch is to remain serving as the Principal Switch in the FC Fabric.
