qlEnable qlEnable Enable QuickLoop mode. Synopsis qlEnable Availability Admin Release V3.1.x Description Use this command to enable QuickLoop mode on a switch. All devices connected to QuickLoop ports are re-initialized to form a single loop. If a partner switch is configured, qlEnable causes re-initialization of the partner if it is in QuickLoop mode. The devices on the two switches are then combined to form a single loop (using a single AL_PA space). QuickLoop combines arbitrated loop and fabric topologies. It consists of multiple private arbitrated loops (looplets) interconnected by a fabric, with the existence of the fabric and the physical locations of the devices transparent. All NL_Ports share a single AL_PA space, and operate in accordance with FC-AL. QuickLoop initialization includes the following two steps: 1. Pass 1: Sequential looplet initialization. Allows each device in a looplet to obtain a unique AL_PA. 2. Pass 2: Full QuickLoop initialization. Brings the QuickLoop up to operation. Fabric OS Version 3.1.x/4.1.x Reference Guide 647
