How does the system know about the AoE targets on the network?
When an AoE target comes online, it emits a broadcast frame indicating its presence. In addition to this mechanism, the AoE initiator may send out a query frame to discover any new AoE targets. The Linux aoe driver, for example, sends an AoE query once per minute. The discovery can be triggered manually with the “aoe-discover” tool, one of the aoetools.
