Using QuickLoop Fabric Assist Mode LIP Propagation and Private Targets LIPs of the private host loop are not propagated back to the loop's Fabric Assist targets. A Registered State Change Notification (RSCN) will be generated, and thus public targets that have registered for SCN will be notified of any configuration changes. If the host re-LIPs without causing a configuration change, then no RSCN will be generated. Private targets will not register for SCN, and without LIP propagation, they rely on higher-level protocols for error recovery. This is similar to QuickLoop Translative Mode, where the private loop targets zoned with public hosts are not re-LIPed due to changes in the status of the public host. Specifying private targets inside a Fabric Assist zone does not affect normal operation of the other public members of the Fabric Assist zone. A phantom AL_PA for the private host is added to the private target's loop when the first ELS command is sent from the private host. Private hosts LIP only when phantoms are added. Private targets can not be on the same switch as the private host in which they are Fabric Assist zoned. If Fabric Assist zoning with a private target is required than the private target must be connected to another switch within the fabric. Public targets that will be Fabric Assist zoned may be connected anywhere including the same switch as the private host. If LIP propagation to the target loop is required, then the private targets that need to be accessed by a private host should be placed within a QuickLoop instead of a Fabric Assist mode zone. Fabric Assist Mode Hosts and QuickLoop Zoning Fabric Assist hosts may not be on a switch that is running QuickLoop. If any port of a 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. Quickloop Fabric Assist User Guide 35
