Configuring and enabling FC fastwrite The FC-FC (Fibre Channel) Routing Service provides Fibre Channel routing between two or more fabrics without merging those fabrics. The FC-FC Routing Service can be simultaneously used as a Fibre Channel router and for SAN extension over wide area networks (WANs) using FCIP. Take the following steps to configure and enable FC fastwrite. 1. Create a zone configuration to filter FC fastwrite flows. FC fastwrite flows are configured by creating a zone name with an fcacc token as a prefix. For LSAN configuration, use lsan_fcacc as a prefix, as shown in the following example.. #zonecreate fcacc_myzone1, "initiator-wwn; target-wwn" #zonecreate LSAN_fcacc_myzone2, "initiator-wwn; target1-wwn; target2-wwn" #cfgcreate mycfg, "fcacc_myzone1; LSAN_fcacc_myzone2" #cfgenable mycfg 2. Enable FC fastwrite using the fastwritecfg command. Enabling or disabling FC fastwrite with this command disrupts data traffic. For the FR4-18i blade, the command powers the blade off and back on. In the case of the 400 Multi-protocol Router, the switch is rebooted. The process takes up to five minutes. #fastwritecfg -enable slot# Where: slot# is the slot in which the FR4-18i blade is installed. A slot number is not required for the 400 Multi-protocol Router. Example: SJ3_6A1_12000_0:root> fastwritecfg --enable 7 !!!! WARNING !!!! Enabling FC Fastwrite will require powering off and back on the and it may take upto 5 minutes. For non bladed system, the switch will be rebooted. Data traffic will be disrupted. Continue (Y,y,N,n): [ n] y SJ3_6A1_12000_0:root> fastwritecfg --disable 7 !!!! WARNING !!!! Disabling FC Fastwrite will require powering off and back on the and it may take upto 5 minutes. For non bladed system, the switch will be rebooted. Data traffic will be disrupted. Continue (Y,y,N,n): [ n] y Slot 7 is being powered off 3. Enable FC fastwrite on the ports using the portcfg command. #portcfg fastwrite slot#/port_id -enable Where slot# is the slot in which the FR4-18i is installed. A slot number is not required for the 400 Multi-protocol Router. 460 Configuring and monitoring FCIP extension services
