contact your switch supplier to obtain a license key. QuickLoops require a Compaq StorageWorks Fibre Channel SAN Switch with Fabric Operating System Version 3.0 or later installed. You can install a QuickLoop license either through telnet or through Web Tools. Quickloop Fabric Assist User Guide 15 - HP StorageWorks 2/8-EL | quickloop fabric assist version 3.0.x user guide - Page 16
QuickLoop Using Telnet 1. Log onto the switch by telnet (see the user guide provided with the hardware for details), using an account that has administrative privileges. 2. If you want to determine whether a QuickLoop license is already installed on the switch, type licenseShow on the telnet command - HP StorageWorks 2/8-EL | quickloop fabric assist version 3.0.x user guide - Page 17

QuickLoop Topology QuickLoop topologies have the following characteristics: ■ A QuickLoop can include up to two switches and can support up to 126 AL_PA devices. ■ Each switch drivers need no modification to perform I/O operations with storage devices. ■ Public devices that are arbitrated loop - HP StorageWorks 2/8-EL | quickloop fabric assist version 3.0.x user guide - Page 22
on a switch. There are 8, 16 or 32 physical ports on varying models of a Compaq StorageWorks Fibre Channel SAN Switch; certain models constrain the type of port the switch can support. Each port can be independently configured as one of the following types. 22 Quickloop Fabric Assist User Guide - HP StorageWorks 2/8-EL | quickloop fabric assist version 3.0.x user guide - Page 23

The standard QuickLoop implementation imposes the following limitations: ■ A QuickLoop is confined to at most two switches in a fabric. ■ There can only be 29 private hosts supported in a QuickLoop. ■ Even though a target device can be public, it is forced to perform as a private - HP StorageWorks 2/8-EL | quickloop fabric assist version 3.0.x user guide - Page 35
loop when the first ELS command is sent from the private switch is configured to be a QuickLoop port, then you can not connect a Fabric Assist host to the switch. A switch with a Fabric Assist host, will not allow any of its ports to be configured as a QuickLoop port.
